Alloy steel with silicon content of 1.0 ~ 4.5% and carbon content of less than 0.08% is called silicon steel. It has the characteristics of high permeability, low coercivity and high resistivity, so the hysteresis loss and eddy current loss are small. It is mainly used as magnetic material in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing processing in the manufacture of electrical appliances, it also requires a certain degree of plasticity. In order to improve magnetic susceptibility and reduce hysteresis loss, the content of harmful impurities is required to be as low as possible, and the plate type is smooth and the surface quality is good.
Electrical steels (silicon steel sheets) are mainly divided into two categories: Grain oriented electrical steel and Non-oriented electrical steel.
Oriented electrical steel easily magnetized grain direction distribution along the rolling direction, rolling direction has high magnetic induction, low iron loss and low magnetostriction and other excellent characteristics, but also through the magnetic domain thinning technology processing, to obtain lower iron loss performance, widely used in transformer industry. Non-oriented electrical steel is widely used in motor industry with random distribution of grain direction and uniform electromagnetic properties.
