On September 17, 2019, when the general secretary inspected the shares of Zhengzhou Coal Mining Machinery Group, he emphasized that the manufacturing industry is the foundation of the real economy, and the real economy is the capital of China's development and an important support for building strategic advantages for future development. It is necessary to firmly promote industrial transformation and upgrading, strengthen independent innovation, develop high-end manufacturing and intelligent manufacturing, improve China's manufacturing industry and the real economy, and promote China's economy from large quantity to strong quality.
We keep in mind the entrustment of the general secretary, and strive to build Zhengmei Machinery into a high-end intelligent equipment industry group with international influence, and contribute to the revitalization of the national equipment manufacturing industry and the Chinese brand to the world. Jiao Chengyao, Secretary of the Party Committee and Chairman of Zheng Coal Machinery Group, said.
Service intelligent fully mechanized mining
Looking back at history, the spark of China's coal mining mechanization journey was ignited from the Zheng Coal Mining Machine. From the first domestic hydraulic support, to the first electro-hydraulic control system with independent intellectual property rights, and then to the first set of intelligent complete sets of equipment in China, Zhengmei was born and prospered because of innovation. Behind this is not only the mission of a state-owned enterprise, but also the spur of competition from the market. It can be said that Zheng Coal Machinery, which has a history of more than 60 years, is a typical sample of interpreting the development code of China's equipment manufacturing industry.

Revitalize the national equipment manufacturing industry and make new contributions to the Chinese dream of the great rejuvenation of the Chinese nationThis sentence is engraved on the wall of Zheng Coal Mining Machine, and it is engraved in the hearts of Zheng Coal Mining Machinery people.
China is rich in coal resources, but the occurrence conditions are complex, which leads to the coexistence of various coal mining methods such as top coal mining, layered mining, and one-time mining of full height. Among them, the full height of a mining is a one-time mining of all coal seam thickness of the technology, in the working face coal seam thickness uneven distribution, inclination angle change and other complex geological conditions across the height limit mining, often because the support support height is not low enough and the gangue occurs, or the support height is not high enough and the coal is lost. "Fully mechanized mining supports are non-standard products that need to be customized according to specific mining conditions. The slight changes in height, the supporting force, stability, safety protection and other related technical indicators of the product must be adjusted in a complex manner, and new requirements are put forward for the strength of materials and product structure. Liu Fuying, assistant general manager of the coal machinery sector of Zheng Coal Machinery Group, said.
In order to solve the technical mining problems under complex geological conditions such as uneven distribution of coal seam thickness and large change in dip angle, in 2018, Zheng Coal Mining Machinery and Ningxia Coal Industry of the National Energy Group jointly carried out the research on the project of "R&D and Application of Fully Mechanized Mining Technology and Equipment for Hydraulic Support with Large Expansion and Contraction Ratio". To this end, Zhengmei has established a R&D team composed of general manager, chief engineer, president of the design institute and chief expert to continuously optimize and improve the design scheme. At the same time, in view of various technical problems, we have jointly developed 1000 megapascal high-strength steel plates, large-bore high-strength S890 pipes and supporting high-strength welding wires and welding processes with steel enterprises, and overcome key technologies such as corrosion resistance technology on the surface of columns and jacks, as well as welding deformation control of large-scale heterogeneous structural parts.
Hard work pays off. In 2021, Zhengmei Machinery obtained the industry's first 450 three-telescopic column new product safety standard certificate, and the first ZYA12000 18 50D cover hydraulic support mining product safety mark certificate. Today, the results of the project have been applied to two projects, Meihuajing Coal Mine of Ningxia Coal Industry of National Energy Group and Guojiawan Coal Mine of Yulin Energy of National Energy Group, with a total of 358 brackets promoted and applied. "Compared with the traditional mining method, the current set of equipment can replace the original two or three sets, reducing the time for equipment moving and reversing, and improving the resource rate by 15 to 20. Liu Fuying said.
On the basis of technology introduction, Zhengmei Machinery has digested, absorbed and re-innovated through technical research and development again and again, and has stepped up step by step in the research and development field of high-end fully mechanized hydraulic supports with high resistance, high reliability, high mining height and full automation. 6.5 meters, 7 meters, 8 meters ......8.At 8 meters, Zheng Coal Mining Machinery continues to refresh the world record for the support height of hydraulic support for large mining heights. In 2023, the first batch of 10-meter super-large mining height two-column shielding hydraulic support provided by Zheng Coal Machinery for Shaanxi Coal Caojiatan Coal Industry will be delivered and put into use, once again creating a new height of coal mine support equipment in the world, which is also the hydraulic support with the highest support height, the largest working resistance, the longest expected service life, the largest supporting production capacity and the most advanced intelligent technology in the world.
In recent years, improving quality and efficiency has become the development theme of the coal industry. On the one hand, coal production is increasing, and on the other hand, the number of coal mines is declining in an orderly manner, and the demand for efficient production tools in coal mining is becoming increasingly strong.
Market changes require Zheng Coal Mining Machinery to take the initiative to embrace the intelligent wave of the industry.
Since 2019, Zhengmei Machinery has formed an innovative idea of "driving the development of complete sets of products with intelligence, and driving the whole process of business transformation with digital". After overcoming the problem of localization of the stent electro-hydraulic control system, Zhengmei Machinery took Hengda Intelligent Control as the main body and gradually expanded from the bracket hydraulic control system to the stent electro-hydraulic control system, and then to the intelligent mining operating system that can control the whole working face equipment to create an integrated control system.
In the past, domestic manufacturers did not have the ability to provide complete sets of fully mechanized mining equipment, and customers were also accustomed to purchasing a variety of equipment from different manufacturers. As a result, the equipment operates independently, the system data exchange is limited, and multi-protocol conversion is required during actual operation and maintenance. Once the customer uses the first problem, the manufacturers need to negotiate together to solve the problem, which seriously affects the mining efficiency. Wang Yongqiang, deputy general manager and chief engineer of the coal machinery sector of Zheng Coal Machinery Group, told reporters, "After the complete set, various equipment will use a unified control platform and communication protocol, and the data will be completely open, realizing the collaborative work of multiple equipment." ”
In 2020, Zhengmei Machinery launched the first complete set of intelligent fully mechanized mining face in China with a single manufacturer providing shearers, scraper conveyors, hydraulic supports and intelligent control systems, which was applied to the No. 2 Mine of China Pingmei Shenma Energy and Chemical Group Co., Ltd. (hereinafter referred to as "Pingmei No. 2 Mine").
The coal seam of Pingmei No. 2 Mine is thin and the geological structure is complex, and the original fully mechanized mining equipment causes high quarrying volume and high cost. The successful commissioning of the intelligent fully mechanized mining equipment has not only released more than 10 million tons of thin coal seam reserves for the mine, but also greatly extended the service life of the mine.
Originally, the monthly coal mining propulsion was 80 to 90 meters, but after using Zheng Coal Machine's complete set of intelligent equipment, the propulsion is now maintained at 180 to 200 meters, with a record of 267 meters. Moreover, the equipment performance is reliable and the failure rate is low. In an interview with reporters, Ma Zhaohui, director of the second mine of China Pingmei Shenma Energy and Chemical Group Co., Ltd., praised the complete set of intelligent equipment of Zhengmei Machinery that has been used for more than two years.
Collaboration achieved by intelligence is not limited to machines. Through cooperation with well-known domestic communication equipment companies and artificial intelligence companies, the intelligent system of Zhengmei Machinery connects the underground and surface scheduling. The reporter saw that more than 10 sensors are installed on each bracket in the mine, which can capture the location information of underground machinery and personnel in real time and upload it to the control center on the mine. The equipment equipped with detection sensors such as gas and dust can keenly capture danger signals and remind or terminate the operation of mining work in time. The large screen of the surface dispatch center displays various production and safety indicators in the underground. Through 5G transmission technology, the ground workshop can remotely control the three machines on the working face, and restore the position and attitude of the equipment in the digital twin system, which not only realizes ground monitoring and remote control, but also solves the problem of equipment signal delay during the original remote operation.
In the past, a working face alone required more than a dozen employees, plus the operators of shearers, scrapers and other equipment, and the equipment coordination relied on the voice. Now all kinds of machinery are coordinated by a 'brain', and the overall work efficiency has been greatly improved. Meng Hechao, deputy general manager of the coal machinery sector of Zheng Coal Machinery Group, said.
Wang Yongqiang told reporters that since 2019, Zheng Coal Mining Machinery has taken the localization of key components of the intelligent control system as the direction of tackling key problems. In 2021, relying on the first-class electronic control system of Zhengmei Coal Mining Machine, the first set of Zhengmei Gigabit Ethernet Bracket Electronic Control System equipped with the "Mine Hong" system will be applied in the underground underground of the Bultai Coal Mine of Shendong Coal Group, realizing the independent and controllable key technologies of the intelligent system of the fully mechanized mining face of the coal mine. By the end of 2022, Zhengmei has promoted a total of 514 intelligent working faces, with a market share of 42, and the core components of intelligent equipment have basically been fully localized.
Today, Zheng Coal Machinery's main business covers complete sets of equipment for fully mechanized coal mining faces, intelligent coal control systems, R&D, design, production, sales and life cycle services of smart mines, and the products are sold all over the country and exported to many countries and regions.
Luozi advanced manufacturing
Digital and intelligent products are inseparable from modern production. As a practitioner of intelligent manufacturing, Zhengmei not only provides intelligent industrial products, but also applies digitalization and intelligence in production.
As a unit responsible for the production of important parts, Hengda Intelligent Control has more than 700 employees, of which less than 100 are responsible for processing and production. The secret behind efficient production is digitalization and intelligence.

There is a display screen at the door of Hengda Intelligent Control production workshop, which shows the effective utilization rate of workshop equipment every day. As soon as the effective utilization falls below the normal range, the staff immediately needs to find out the cause. In the production area of robotic arms and CNC machine tools, Zhang Xingfu, deputy general manager of Hengda Intelligent Control of Zhengmei Machinery Group, told reporters that Hengda Intelligent Control has achieved a high degree of mechanization in production, and in order to improve the efficiency of equipment operation, the company has jointly developed a production management system with external units. The system connects the operating status of each machine tool to the network, and the operating status can be detected in real time through the management interface. As long as the raw materials are ready for production, 24-hour unmanned production can be realized.
The robotic arm is waving rhythmically, the laser cutting sparks are flying, and the intelligent crane and the automatic guided vehicle are busy working overhead and under the feet...... respectivelyWhen I came to the digital factory of structural parts in Zhengmei Smart Park, I found that intelligent industrial production was so shocking. Here, the smart factory can automatically perceive the production demand materials, inventory and in-transit materials, automatically balance the material requirements through the smart platform, automatically generate purchase plans, etc., and synchronously distribute them to the machine. Transportation of production raw materials into the factory, from unloading to transportation, to cutting, welding and other technological processes, and finally to form a finished product, the whole process without manual intervention. In addition, the smart factory will implant a chip for each product, forming a quality file that can trace the entire life cycle of the product.
Luozi intelligent manufacturing, Zheng Coal Machinery also had concerns. As a discrete manufacturing enterprise, Zhengmei has a variety of product types, a high degree of customization, a complex and changeable manufacturing process, a difficult digital promotion, high requirements for production equipment, and no mature model for project construction to refer to. In addition, the investment in infrastructure and equipment of smart factories in the early stage is high, and the construction is difficult, and the project faces many uncertainties.
Do you want to do it?Dry!"A new round of information technology revolution and industrial transformation is accelerating, and Zhengmei Machinery urgently needs to grasp the opportunity of digital transformation, improve the level of product intelligence and production efficiency, and meet the challenges from the market. Jiao Chengyao said.
How?Let go of your hands and feet!Test it yourself without application experience, and experiment by yourself if there are no cases. Through rounds of inspection, demonstration and selection of equipment, from the selection of laser cutting equipment, to the innovation of the mode of "welding robot positioner automatic driving and single dust removal", and then to the attempt of solid powder spraying process, Zheng Coal Mining Machinery explored all the way around the difficulties, pain points and blocking points of digital factory construction, and finally determined the construction drawings of the smart factory.
Jiao Chengyao told reporters that the entire project team was less than 20 people when it was formed. In the installation and commissioning stage, the on-site construction personnel are complex, and there are up to 16 units interspersed with construction. Relying on the determination not to admit defeat, the entire project team successfully completed the installation and commissioning of more than 700 pieces of equipment in the smart factory in less than 11 months, realizing the full line of intelligent production.
In order to make the project land as soon as possible, the project team uses the pilot product as the carrier to carry out vertical management of the project and realize the integrated collaborative office of design, process and manufacturing. In the face of industry innovation problems, Fu Lighting, the head of the project design process integration team, led the project team to complete dozens of studies such as model design method research based on integrated data, construction of standard process system of smart park, automatic generation of intelligent computer-aided design system, etc., and built an integrated platform system of design, process and manufacturing based on the characteristics of Zheng Coal Mining Machine, which has completely independent intellectual property rights from the system layer, tool layer, business layer to the platform layer.
Facts have proved that the step of intelligent manufacturing Zheng Coal Machine is right, and the improvement of production efficiency says everything. Jiao Chengyao told reporters, "Compared with the traditional production mode, the efficiency of the smart park after operation is increased by more than 2 times, the space utilization rate is increased by 50, the material replenishment speed is increased by more than 10 times, the production cost is reduced by more than 60, and the production delivery time of 100 aircraft is shortened from 28 days to 9 days."
In April 2022, the intelligent manufacturing demonstration base project of Zhengmei intelligent control system officially started. After the completion of the project, it will become a demonstration base for intelligent manufacturing of fully mechanized mining control system and high-end bracket valves, which can comprehensively improve the lean, automation and intelligent level of the enterprise, and help Zhengmei Machinery transform from a production-oriented to a scientific and technological service-oriented enterprise.
The pursuit of high-end and intelligence has only a starting point, not an end. Jiao Chengyao said that the group will continue to seek breakthroughs in digital and intelligent products and production in the future.
Innovative lean management
Technological innovation in the manufacturing industry is inseparable from the innovation of production management.
Lean starts from the heart, and improvement starts from me. This is the management key extracted by Zheng Coal Mining Machine. In 2010, Zheng Coal Machinery organized a team to go abroad to investigate and learn management experience, and introduced a consulting company for counseling in the following year.
Since 2019, on the basis of summarizing and implementing nearly 10 years of lean management experience, Zhengmei Machinery has built a value-oriented lean management system, making full use of value stream analysis thinking, eliminating waste, and improving production capacity and efficiency.
Case 1: How to reduce the cutting error?
The team of Yin Shengchao, general manager of Zhengmei Machinery Structural Parts Company, is responsible for the production of the main structural parts of the hydraulic support, which is a key process. The problem they encountered was that the quality of the robot's bevel was unstable, and the cutting speed was too fast, which would lead to cutting defectsIf the cutting speed is too slow, it will cause thermal distortion;Improper cutting paths can lead to incomplete cuts or wasted material. After the establishment of the lean improvement project team, in order to determine the plasma cutting process, Yinshengchao led the team to work on site for 15 days, constantly adjusting the cutting speed, path planning and other parameters, and striving to find the best process parameters for different sizes and shapes of groove cutting. In the experiments again and again, the team worked out the plasma cutting process parameters, replaced the flame cutting gun with a plasma cutting gun, and used the characteristics of plasma to cut, the speed was increased by more than 3 times, and the cutting quality was ensured at the same time, and the cutting error caused by thermal deformation was reduced.
Case 2: How to remove the blockage of iron filings?
When CNC machine tools process small hole workpieces, the iron filings in the hole will be discharged with the chip liquid, which is easy to cause blockage. The original method is to suspend the equipment during the processing process and manually hook out the iron filings in the hole with a hook. It takes two minutes from opening the door to hooking the filings and closing the door. Wang Haipeng, director of Zhengmei Hengda Intelligent Control Machine Processing Area, led the improvement special team, consulted the information, repeated tests, and finally designed and produced a set of blowing devices from the center, which was installed in the spindle hole of the CNC machine tool, connected to the high-pressure air pipe, and controlled by the programmable logic controller of the machine tool program, so that the CNC lathe blew while turning during the processing process, and at the same time completely removed the iron filings in the hole. This improvement has been extended to other machine tools with similar processing in the work area, which completely solves the problem of blockage of iron filings in small holes in CNC machining.
Case 3: How to improve the clamp installation process?
Because the product has updated the column structure, the clamp installation of the Zhengmei Jizhiding Hydraulic Cylinder Business Department has become a hindering process. The clamp will produce deformation stress during the machining process, resulting in serious warping during the bolt fixing process, and the outer circle of the workpiece cannot be tightly fitted, which will increase the difficulty of fastening. It takes 3 people to cooperate with the clamp every day, and only 10 clamps can be installed in one shift. Zhang Jinglei, deputy director of the cylinder block business department, meditated hard and found a way to use cylinder compression to assist in tightening the cylinder clamp. 16 sets of finished products can be welded and installed by a single person, and the problem of long screws and slippery wires can be effectively avoided at the same time. This improvement is nearly 5 times more efficient.
The highest level of management is to fully mobilize people's internal motivation.
A typical lean improvement announcement of Zheng Coal Mining Machinery reads: "Yinwencai structural parts are integrated with boring tools", which improves the processing efficiency of finishing and boring 20, and increases the effective working time of each whole equipment by 6 per day5 hours, cancel the grinding of welding tools, reduce the frequency of tool change, tool setting and size measurement.
The role of the Lean Improvement Mechanism named after the employee in developing skill masters should not be underestimated. Qin Yongfeng introduced to reporters the experience of becoming a skill master: "On the one hand, you must have a strong learning ability and be able to continue to study problems;On the other hand, love the job from the bottom of your heart and want to do it better. Qin Yongfeng has been engaged in the research, quality improvement, and process improvement of cylinder CNC machining technology for 20 years, and has trained 2 skill masters for Zheng Coal Mining Machine.
Skill master Sang Ruilong entered Zhengmei Machinery in 2006, he has rich experience in electrician maintenance, led the team to participate in more than 200 equipment improvement proposals, saving more than 55 million yuan.
Wang Yongqiang told reporters: "We encourage employees to learn new knowledge, master new skills, and embrace new changes. We also focus on cultivating employees' sense of innovation and creativity, and stimulating their enthusiasm and entrepreneurial spirit. We believe that in the big family of Zhengmei Machinery, everyone can find their own stage and value. ”
It is Qin Yongfeng, Sang Ruilong, such as the pursuit of excellence of skilled workers, to support the continuous upward "support" of Zheng Coal Mining Machine, and to achieve the vivid application of lean management in Zheng Coal Mining Machine.
Diversified layout development
People have no long-term concerns, but there must be near-term worries, and the same is true for enterprises. The development pulse of the coal industry is driving the pace of Zheng Coal Mining Machine.
Coal is the main energy source in China, and the coal industry has started a 10-year period of rapid development since 2002. Benefiting from this, the sales of coal machinery equipment have also grown rapidly. In 2012, Zheng Coal Machinery's operating income hit a historical peak of 10.2 billion yuan. However, the ensuing downward cycle of the coal industry made the business conditions of Zheng Coal Machinery fluctuate violently. With the proposal of the "dual carbon" goal, China Coal Industry Association**, before 2030, China's coal consumption will enter the total peak platform, and then turn into a total decline. The coal industry has entered the countdown to comprehensive transformation.
This transformation pressure is also transmitted to Zheng Coal Machine.
Adhere to the industry and focus on the main business. In the face of pressure, Zheng Coal Mining Machinery is highly certain in the understanding of transformation. Enterprises need to deepen reforms and upgrade the "operating system" to provide lasting impetus for future development.
Zhengmei Machinery is a H-share listed company, with 28 production, R&D and sales bases, covering 17 countries and 1 employeeMore than 60,000 people. As a state-owned enterprise reform "Double Hundred Action" enterprise of the State-owned Assets Supervision and Administration Commission and a pilot unit of the double reform of mixed ownership economy and professional managers in Henan Province, Zheng Coal Machinery is the pioneer, practitioner and beneficiary of the previous state-owned enterprise reform. In 2021, Zheng Coal Machinery completed the "second mixed reform" and introduced strategic investment, realizing the transformation of state-owned assets supervision from "managing people, managing affairs and managing assets" to "managing capital", further optimizing the shareholder structure, and further marketizing the enterprise system and governance institutions, which is more conducive to enterprises to participate in international competition.
For middle and senior managers, technology research and development, sales and production backbones, the company has successively formulated and implemented medium and long-term super profit incentive plans, first-class option plans, restrictive first-class incentive measures and other incentive measures, and initially carried out medium and long-term incentive attempts that are compatible with the talent market and linked to the economic benefits of the enterprise, and tried to establish a lifelong partner mechanism.
The deepening reform has brought surging impetus to the enterprise. Taking the traditional coal machinery business as an example, in the first three quarters of 2023, the orders of the coal machinery business of Zhengmei continued to grow, and the total operating income of the coal machinery segment reached 1417.2 billion yuan, an increase of 1493％；Net profit was 249.1 billion yuan, an increase of 32 over the same period last year20％。
The development of enterprises needs to rely on the main business to open up new strategic space. Opening up a second battlefield beyond the influence of the coal industry in addition to the coal machine is the strategic focus of Zheng Coal Machinery for the future.
Since 2000, through a series of institutional reforms, we have completed a magnificent transformation from a cocoon to a butterfly and a rebirth of Nirvana. Jiao Chengyao introduced that the operating income of Zheng Coal Machinery climbed from less than 100 million yuan in 2000 to 10.2 billion yuan in 2012. However, in the following years, along with the cyclical downturn of the coal industry, the proportion of coal in primary energy consumption gradually declined. Zheng Coal Machinery has also encountered a bottleneck in development, operating income fell to 3.6 billion yuan in 2016, Zheng Coal Machinery to build a century-old enterprise, must break through the bottleneck of industry development.
In 2015, Zheng Coal Machinery began cross-border transformation and explored the development of the second main business.
In line with the overall principle of leaving the industry and not leaving the profession, Zhengmei chose to enter the field of auto parts that belong to the same machinery through mergers and acquisitions, transforming from resource-driven to scientific and technological innovation-driven, from domestic business to global business development, and entering the auto parts manufacturing industry with a high starting point and high standards. Jiao Chengyao said that after repeated demonstrations, Zheng Coal Machinery has determined eight principles of transformation: first, to enter a larger field;Second, the market has a certain growth;Third, the concentration of the industry should not be too high;Fourth, the upstream and downstream cannot be monopoly industries;Fifth, enter by way of mergers and acquisitions;Sixth, it ranks among the top three in the industrySeventh, the industry and enterprises recognize the culture of Zheng Coal Mining Machine;Eighth, it is best for the enterprise team to have industry leaders or potential leaders.
In 2016, Zheng Coal Machinery acquired six auto parts companies of ASIMCO, a subsidiary of Bain Capital, for 2.2 billion yuan. In 2017, Zhengmei successfully acquired the global starter and generator division of Bosch in Germany, obtained 9 factories, 1,000 patents, 600 R&D teams, marketing and sales network and customer resources of Bosch's motor division, and mastered the core technologies in key fields such as automobile lightweight, comfort, energy conservation and emission reduction, becoming the world's third largest automotive engine and generator company.
At present, Bosch Motor has changed its name to SEG Automotive Germany GmbH (Chinese abbreviated as 'SEG Ag'), the company has a global R&D, production, sales and service network, holds nearly 1,000 patents, accounts for 20% of the global automotive motor market share, and also masters core technologies in key areas. In terms of business, synergy with ASIMCO has laid the foundation for building a world-class auto parts company. Jia Hao, general manager of Zheng Coal Machinery Group, introduced that after three years of industrial transformation and mergers, Zheng Coal Machinery officially entered the trillion-level auto parts market, has a global auto parts research and development, production, sales and service network, and has accumulated rich experience in machinery industry integration, mergers and acquisitions and management, realizing the dual main business drive of coal mining machinery and auto parts, and has three well-known brands in the manufacturing industry: Coal Mining Machinery, ASIMCO and SEG.
Facing the future, SEG and ASIMCO have stood at a new starting point and unswervingly entered the new energy track. "While optimizing and refining the traditional business, ASIMCO focuses on the research and development of intelligent and lightweight core components and system assemblies for electric vehicles. Jia Hao said that ASIMCO continued to explore noise and vibration reduction and sealing technologies for new energy vehicles, developed air suspension systems, achieved significant growth in its international business and new energy business, successfully entered the first-class chain system of new energy vehicles, and fully started the pace of transformation to the new energy field. In order to promote the implementation of the electrification strategy of the company's auto parts sector and seize the historical opportunity of the development of the new energy vehicle market, SEG Automotive Electric Systems focuses on the testing, development, manufacturing, sales and engineering services of automotive electric drive systems, with the goal of becoming a first-class enterprise in the world of new energy drive motor systems. Jia Hao introduced that SEG has rapidly promoted the research and development and application of high-voltage drive motors, and has entered the first chain of electric drive systems for new energy vehicles from a high starting point, and has successfully obtained orders from leading enterprises.
Another strategic space that Zheng Coal Mining Machinery is trying to open up is to transform the original industrial heritage into a dual-innovation park.
No. 105, Huashan Road, Zhongyuan District, Zhengzhou City, is the location of the old factory of Zhengzhou Coal Mining Machinery. In the context of urban renewal and industrial upgrading, Zheng Coal Machinery reshaped the industrial heritage into a space carrier of culture, art, and leisure consumption, "Sesame Street", hoping to leave a touch of "industrial nostalgia" for the city. Fu Qi, deputy general manager of Zhengmei Machinery, introduced that Sesame Street is an industrial park in the form of innovation and innovation integration based on historical industrial heritage, industrial upgrading and transformation as the development direction, and urban renewal and development as the integration opportunity. The name of Sesame Street is also derived from the pinyin initials ZMJ of "Zheng Coal Machine", which means "sesame blossoming is high".
Zheng Coal Machine's move to revitalize the situation.
On the southwest side of the park, a renovated factory building is named "Zhongyuan International Design Valley".
The renovated plant brings together more than 10 upstream and downstream design enterprises, forming a small industrial chain in the same physical space, cooperating and colliding with each other to stimulate the vitality of innovation and development. Li Xia, general manager of the Zhengzhou branch of Shanghai Lianchuang Architectural Design Company, said.
Fu Qi introduced that after the Zhengzhou branch of Shanghai Lianchuang Architectural Design Company entered the park, it attracted new materials, curtain walls, garden landscapes, construction and other units, forming upstream and downstream gatherings. At present, the park has settled in a number of enterprises and scientific research institutes, involving industrial R&D and design, energy conservation and environmental protection, inspection and testing, information big data and many other fields.
To gather the main business, it is also necessary to make a long industrial chain.
In July 2022, Luoyang LYC Bearing*** hereinafter referred to as "Luoyang Shaft Company") carried out a mixed ownership reform, and Zheng Coal Machinery participated in it as a shareholder. By promoting the reform experience of Zheng Coal Mining Machine, the overall production and operation situation has been greatly improved. In the next step, Zheng Coal Machinery will sort out the future development path for Luozhou Shaft Company, strengthen independent innovation, and enable the company to enter the capital market as soon as possible.
Zheng Coal Machinery plans its future in this way: within 5 years, it will achieve deep intelligence and internationalization. In the next 10 to 15 years, with service as the core, we will integrate the existing coal machinery plants under the Mining Bureau to provide life-cycle services. Focusing on the development of new energy, we will continue to launch innovations similar to ASIMCO's intelligent suspension and SEG new energy three-in-one electric drive system. In 2025, we will strive to achieve an operating income of 50 billion yuan, and by 2030, we will strive to achieve an operating income of 100 billion yuan.
From fully mechanized mining to intelligent mining, from production-oriented enterprises to scientific and technological service-oriented enterprises, from China to the world, the innovation and upgrading of Zhengmei Machinery has been solid step by step. With the continuous progress of China's equipment manufacturing industry, the development story of Zhengmei Machinery is still being updated.
