On March 1, the 2023 "Great Country Craftsman of the Year" release event hosted by the All-China Federation of Trade Unions and ** Radio and Television Station announced 10 "Great Country Craftsman of the Year" in Chengdu, Sichuan Province. Dong Litao, a high-skilled expert of Harbin Electric Group, was successfully selected.
The reporter learned from Harbin Electric Power Group that Dong Litao joined Harbin Electric Power Group Steam Turbine Company in 1989 and became an apprentice miller. For more than 30 years, Dong Litao has carried the dream of "building a manufacturing power", rooted in the production line, grown from an ordinary apprentice, and won the China Skills Award, National Technical Expert, National Model Worker, and National Craftsman of the Year. Dong Litao not only played an active role in promoting the transformation and development of enterprises, but also contributed to the high-quality development of the equipment manufacturing industry.
Casting heavy weapons for the country, Dong Litao's road to a great craftsman
In more than 30 years, he has grown from an apprentice determined to do a good job as a milling worker to an award-winning technical expert, and has been "promoted" from a young industrial worker to a national master craftsman.
On March 1, he was awarded the annual figure of the great craftsman Dong Litao of Harbin Electric Steam Turbine, has successively obtained more than 20 national patents, completed more than 300 technological innovations, and created more than 8,000 yuan of economic benefits for the enterprise.
Together with rice expert Yuan Longping, his deeds were included in the Chinese Youth Education Series "Builders of the Republic", and became a model for young people to follow.
Love to study and persistent, as soon as you enter the industry, you will "anchor" the expert.
Dong Litao during his apprenticeship was handsome and handsome, wearing a pair of glasses and a thin figure. Down-to-earth work is everyone's collective impression of him; "The small body works hard to study the great wisdom" is the evaluation of the masters on Dong Litao, who has a firm goal.
When I first went to work, the workshop was dimly lit and noisy, and when I was a child, the iron filings would collapse on my body, and I would burn and blister, and the burrs would often prick my hands, and I felt a pain in my heart when I washed my hands with soap after work. Recalling the past, Dong Litao was deeply touched. "But when I saw all kinds of shiny and beautiful parts in my hands, like works of art carved in steel, I slowly began to become interested in working as a miller. ”
Dong Litao also secretly decided, "Since you have done it, you will do it well, you will do it early, and you will never succeed if you do it late!" "With the same machine tool, other millers can control the hole size error at 0In the range of 05 mm, Dong Litao thought about how to be more accurate. Dong Litao is very persistent, studying year after year. In the end, the machining error was successfully controlled at 0Around 01 mm, it has reached the top level.
After completing his regular work tasks, he will always take the initiative to contact some young employees'Super level'and from time to time some bold, unconventional ideas pop up. Talking about Dong Litao's appearance when he first joined the work, the colleagues around him gave a thumbs up.
Dong Litao can always be ingenious and study a unique milling processing method, which greatly improves the work efficiency and product quality of the workshop.
Participating in the company's technical competition, Dong Litao occupied the championship for four consecutive years, broke the company's record at the age of 27, and became the company's youngest senior technician. On behalf of the steam turbine company, he participated in the provincial, provincial, provincial SASAC and other different levels of staff technology competitions, and achieved dazzling results.
Famous teachers lead apprentices", and carry the mission of innovation in the inheritance.
One person's innovation is a small project, and a team's innovation is a big project; The improvement of one person is a small improvement, and the improvement of a team is a big improvement. After growing into a great craftsman, Dong Litao began to play his role as a mentor.
Dong Litao actively responded to the company's call to create a learning team, and set up a "milling work discussion group" in the branch to study milling processing technology and solve production problems. In 2013, the working group developed into the "Dong Litao National Skill Master" studio. As the leader of the studio, he formulates a detailed talent training plan for the studio every year, tailors the "famous teacher and apprentice" activity plan for each studio member, and supervises and assesses it.
In order to make the apprentices willing to learn and learn, Dong Litao devoted himself to combing and compiling his processing experience and methods accumulated over the years into a book for the apprentices to study and study. Today, his apprentices have also stood out in various technical competitions and become the backbone of the company, including 26 technicians and senior technicians.
In the past few years, the innovation studio led by him has overcome many production problems, completed a number of innovative achievements, obtained more than 10 national patents, promoted innovations 245, and naming operation methods, created more than 6,000 yuan of economic benefits for the company, and cultivated a large number of backbone talents.
Explore the transformation and turn "Made in China" into "Created in China".
After Dong Litao became "famous", some headhunters offered high salaries to poach talents. Dong Litao was unmoved, and always stuck to Harbin Electric Group, concentrating on casting heavy weapons for the country.
Here, I feel that my work is closely linked to the fate of the country. "Whenever a key project is put into operation with high quality, Dong Litao and his co-workers are extremely proud. When participating in the construction of the first domestic gas compressor unit, for three years, the passion of the director has always supported Dong Litao's diligent study. In the end, while completing all the tasks as required, 5 invention patents were successfully declared.
West-to-East Gas Transmission and Qinshan Nuclear Power Plant ......That kind of pride, only those who participate can understand", Dong Litao is very proud. The 650,000 kilowatt nuclear power steam turbine of Qinshan Nuclear Power Plant, the largest single unit capacity in China, and China's first real 1 million kilowatt ultra-supercritical steam turbine, have an impeller polished by his own hands. He participated in the processing and manufacturing of the first domestic 30 MW gas compressor unit, which won the crown jewel ...... the equipment manufacturing industry
With the development of the enterprise and the undertaking of more national key projects, Dong Litao feels that he is very lucky to catch up with the good times. "How can you get the most out of your equipment? It is to keep studying skills and turn Made in China into Created in China, which is the most important quality of industrial workers in the new era. "In the era of openness, we have to open the door and reach out, and today's manufacturing is not just about removing processing" ......Recently, Dong Litao is leading the studio to explore the application of 3D printing additive manufacturing technology, and has achieved success in the maintenance and spare parts of imported equipment. In addition, they have also printed solid parts with complex structures, which greatly saves machining time and costs.
Integrate digital technology into manufacturing, and provide accurate basic processing parameter ...... for digital production lines by studying curing processing schemesDong Litao is contributing another strength to the digital transformation of enterprises.
