The iron and steel industry is one of the pillar industries in Hebei Province, and it is one of the key construction project goals of Hebei Province to cultivate the steel industry to high-end, intelligent and green, and accelerate the transformation of "steel to materials, manufacturing to services".
Starting from the promotion of the construction of key high-end steel projects, Hebei Province has been focusing on Shougang Qiangang low-carbon and high-quality steel, Jiujiang short-process high-quality steel, Yanxing board technical upgrading, high-end wire rope of Hangnew Special Steel, Ruikuo intelligent manufacturing and other projects, and continue to promote the steel industry to optimize the structure, pull up the level, extend the chain, and strive to achieve the proportion of high-quality steel to more than 45% and the steel deep processing rate to more than 32% within the year.
High-end silicon steel heat treatment.
For example, the high-end silicon steel heat treatment project of Shougang Zhixin Qian'an Electromagnetic Materials in Qian'an Economic Development Zone, Hebei Province, will start construction in January 2023 and is expected to be fully completed and put into operation in 2025. The project covers an area of 234 acres, with a total planned investment of 244.5 billion yuan, as a key construction project in Hebei Province in 2024, the high-end silicon steel heat treatment project of Zhixin Qian'an Company mainly builds high-end silicon steel heat treatment production lines and supporting plants and other facilities.
The high-end silicon steel heat treatment production line and supporting plants are mainly used for the heat treatment and processing of silicon steel materials. Silicon steel is a kind of low-carbon steel with a silicon content of 3% to 5% (mass fraction), which has good magnetic permeability and low iron loss, and is an indispensable and important magnetic material for the manufacture of motors, transformers, electrical appliances and electrical instruments.
In the production process of silicon steel, heat treatment is an important link. Through heat treatment, the microstructure of silicon steel can be adjusted to further improve its magnetic properties and mechanical properties. Specifically, the high-end silicon steel heat treatment production line mainly carries out the following operations:
1. Annealing treatment: By controlling the heating temperature, holding time and cooling rate and other parameters, the carbon, nitrogen and other elements in the silicon steel are precipitated in the form of compounds, so as to reduce their adverse effects on magnetic properties.
2. Recovery treatment: Heating for a short time at a lower temperature can partially recover the lattice deformity in the silicon steel, reduce the internal stress, and improve the plasticity of the material.
3. Quenching treatment: the silicon steel is heated to the austenite area and then cooled rapidly, so that it can obtain a martensitic structure and improve the hardness and strength.
The supporting plant provides the necessary production environment and equipment support, including heating furnaces, cooling equipment, heat treatment control systems, etc. These equipment and systems together constitute a complete silicon steel heat treatment production line, which provides a strong guarantee for the production of high-quality silicon steel products.
After the completion of the project, it can produce 350,000 tons of high-end non-oriented silicon steel products annually, and is expected to reduce carbon dioxide emissions by nearly 1.7 million tons per year, and achieve sales revenue of 3 billion yuan.
After the production line is completed and put into use, the proportion of high-end products of Shougang silicon steel will usher in a new breakthrough, helping enterprises to further enhance their market competitiveness. The localization rate of key equipment in the production line has increased from less than 20% 10 years ago to more than 90% now.
