On September 8, the Magnetic Materials Research Institute of LNAG Steel Technology Group announced on September 8 that the first test of the research and development of high-performance electromagnetic switch core materials by the institute was successful. The test products have excellent performance, and have the characteristics of high thickness and no coating. . The comprehensive index of this product has reached the international advanced level of electromagnetic switch core materials. After being applied to the production of high-quality electromagnetic switch products, it can effectively improve the usability and reliability of electromagnetic switch products.
It is reported that the production of this product has broken through the limit capacity of on-site unit operation design and improved the equipment capacity and technical level of the production plant. The successful test of this product is of great significance to LNAG non-oriented silicon steel. It not only enriches the variety structure, opens up the application field, expands the product market, and improves the profitability, but also lays a solid technical foundation for the future research and development of related materials. Confirmed the leading position of LNAG non-oriented silicon steel products in the application field of electromagnetic switch industry.
According to reports, the electromagnetic switch is a switch controlled by an electromagnet. When the electromagnet coil is energized, electromagnetic attraction is generated, and the movable iron core pushes or pulls the switch contact to close, thereby connecting the controlled circuit. The core material not only needs to have excellent magnetic induction strength performance and increase electromagnetic attraction, but also needs to have excellent mechanical properties and a higher material thickness, so as to improve the reliability of frequent collisions of the core.
In the world, special non-standard cold-rolled silicon steel sheets are used as special core materials for electromagnetic switches. At present, China has little research on electromagnetic switch core materials. Generally, it is made of ordinary low-grade non-oriented silicon steel or industrial pure iron, although it has good electromagnetic Performance, but the mechanical performance is poor, and the reliability of the product is poor; there is no professional manufacturer of such special electromagnetic switch materials.
Another widespread use of electromagnetic switches is automobile starters. With the improvement of vehicle design and the development of starter-engine integration, the requirements for the reliability of electromagnetic switches have increased significantly, and ordinary iron core materials are difficult to meet the increasing development of high Reliable performance requirements, so high-performance electromagnetic switch core materials with excellent electromagnetic and mechanical properties are the development direction of electromagnetic switch core materials.
