On May 22, Baosteel's 4th Non-Oriented Silicon Steel Application Technology Conference was held in Chengdu. Four new high-performance non-oriented silicon steel products were launched globally, including an extremely thin, extremely low iron loss, high magnetic induction non-oriented silicon steel, which is the world's first product with an iron loss value of less than 9 watts/kilogram. This product will greatly improve the performance and efficiency limit of high-speed motors, and can be widely used in humanoid robots, low-altitude aircraft and other fields in the future.

Non-oriented silicon steel is a soft magnetic alloy with the largest consumption. It is the core material of generators and motors. Its electromagnetic properties play a key role in motor efficiency. As the core power material of a low-carbon economy, Baosteel's non-oriented silicon steel has shown the best comprehensive advantages in new energy vehicles, industrial motors, household appliances, power generation equipment, low altitude and robots, etc., with its excellent high magnetic induction, low iron loss and processing performance, and has won fans at home and abroad.

The four new products released this time are B15AHV950M, B10AHV900M, B50AM250, and 65WY600. Among them, the thickness of B10AHV900M and B15AHV950M are 0.10 mm and 0.15 mm respectively. In particular, the breakthrough non-oriented silicon steel product B10AHV900M is even thinner than an A4 paper. At the same time, the iron loss value is extremely low, that is, the energy loss of the material in the high-frequency alternating magnetic field is extremely low, breaking the 9 watts/kilogram mark that has long been unbreakable in the industry (under 1.0 Tesla 400 Hz magnetization). 

In addition, it has high magnetic permeability, and the magnetic polarization intensity reaches 1.66 Tesla under a magnetic field strength of 5000 A/m, which is the highest magnetic performance in the world. It is understood that "ultra-thin specifications" and "ultra-high performance" cannot be achieved at the same time. This has always been a bottleneck problem that restricts the performance improvement of non-oriented silicon steel, and it is also a problem that restricts the development of various motor industries. Although there are steel companies around the world that can produce 0.1 mm non-oriented silicon steel, there have been no products that can achieve the above three indicators at the same time. The two products B10AHV900M and B15AHV950M have the advantages of "improving driving efficiency and extending the vehicle's cruising range" and will be the best materials for new energy vehicle drive motors.

B50AM250 grade fear-free silicon steel is a benchmark product for evaluating ultra-industrial high-efficiency motors. It features ultra-low loss, ultra-high magnetic induction, and excellent resistance to shear bias degradation. It is used to manufacture the first IE6 super-efficient motor, which is also the world's highest energy-efficiency grade green motor.

65WY600 non-oriented silicon steel is the flagship product of the hydropower industry and an important material to meet the transformation of the pumped-storage generator industry from fixed speed to variable speed. It fills the gap in key materials for pumped-storage variable speed generators. Its high strength, excellent electromagnetic properties, environmentally friendly coating and other characteristics help the power grid to provide high-quality power supply.

Baosteel's non-oriented silicon steel R&D team said that at present, the demand for non-oriented silicon steel products in emerging industries such as new energy vehicle drive motors, industrial robots, and low-altitude economic fields is in a booming period. Baosteel will continue to develop and launch new products to meet the trend of rapid product updates and more personalized performance needs. At present, many new products have been certified by users and have gradually begun mass production. Baosteel will overcome the difficulties faced by the manufacturing end, such as very high equipment precision requirements and high manufacturing difficulty, give full play to the advantages of equipment technology, and be full of confidence to ensure stable product quality and efficient production.
