on-oriented silicon steel with high magnetic induction type and mainstream market demand for new energy vehicle drive motors was successfully trial-produced in the high-performance silicon steel production line in the west area of the plant. This marks that LNAG Group has the production capacity of mainstream silicon steel products for new energy vehicles, and officially opened the "new energy" era of LNAG non-oriented silicon steel.
In recent years, with the rapid development of the world's new energy vehicle industry, China's new energy vehicle production and sales have been steadily increasing, and have been ranked first in the world for four consecutive years. Non-oriented silicon steel products are one of the main products of steel for new energy vehicles. At present, the market demand is huge. However, due to the high requirements on the magnetic properties of mid- and high-frequency steels for new energy steels, the accuracy of composition control, the accuracy of process execution, and the process The rationality of logistics and the uniformity of inspection operations have high system requirements. It is regarded by the industry as "Everest" in non-oriented silicon steel products, and has become the focus of competition among various steel mills.
For many years, silicon steel for new energy vehicles has also been the direction of the efforts of the LNAG silicon steel R & D group. LNAG makes full use of the cooperation opportunity of the silicon steel research and development team of the LNAG Group Iron and Steel Research Institute and a domestic research institute to reorganize and evaluate the control points of each process, key process and key parameters for the production of silicon steel for new energy vehicles. Starting with the level of compositional process control, we innovate the processes of steelmaking, hot rolling, cold rolling, annealing and other processes, and fully optimize the product test plan. In the end, under the influence of LNAG Steel Manufacturing Management Department, it overcame many difficulties and successfully completed the research and development of a series of products with mainstream market demand represented by non-oriented silicon steel, and each technical index reached the advanced level of similar domestic products.
The breakthrough of the key control process of high-inductance and high-brand varieties for new energy vehicle drive motors and the successful trial production of products have laid a solid technology for the subsequent development of LNAG's silicon steel series products for high-energy vehicles and high-quality high-performance series of high-brand products basis.
