The main requirements for the performance of silicon steel are ① low iron loss, which is the most important indicator of the quality of silicon steel sheets. Countries all classify grades according to the iron loss value. The lower the iron loss, the higher the grade. ② The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the volume and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, and insulating materials. ③The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the core. ④Good punching properties are more important for manufacturing micro and small motors. ⑤The surface insulating film has good adhesion and weldability, can prevent corrosion and improve punching properties. ⑥Basically no magnetic aging.
Generally, as the silicon content of silicon steel sheets increases, the iron loss, punchability and magnetic induction decrease, and the hardness increases. The higher the operating frequency, the greater the eddy current loss, and the thinner the silicon steel sheet selected should be.
Silicon steel is mainly smelted in an oxygen converter (electric arc furnace can also be used), combined with vacuum treatment of molten steel and technology (see refining outside the furnace, using die casting or continuous casting. According to different uses, the silicon is changed during smelting (.~ .%) and aluminum (.~.%) content to meet different magnetic requirements. The amount of silicon and aluminum in high-grade silicon steel sheets is increased accordingly. Carbon, sulfur and inclusions are reduced as much as possible.
Magnetic properties of cold-rolled silicon steel sheets , surface quality, filling coefficient and punching performance are better than hot-rolled silicon steel sheets, and can be produced in rolls, so some countries have stopped producing hot-rolled silicon steel sheets since the 1990s. China uses one-time rapid hot rolling at a low temperature of about ℃ and hydrogen protection The stack annealing method is used to manufacture hot-rolled silicon steel sheets, with a high yield rate and good surface quality and magnetic properties of the finished product.
