Silicon steel is a silicon alloy steel with a silicon content of 1.0 to 4.5% and a carbon content of less than 0.08%.
Silicon steel has the characteristics of high permeability, low coercivity, and high resistivity.
Silicon steel is mainly used as a magnetic material in motors, transformers, electrical appliances and electrical instruments.
In order to meet the needs of punching and shearing when manufacturing electrical appliances, silicon steel is also required to have a certain plasticity.
In order to improve the magnetic induction performance and reduce the hysteresis loss, it is required that the content of harmful impurities in silicon steel is as low as possible, and the plate shape is required to be flat and the surface quality is good.
Silicon steel is divided into three categories: hot-rolled silicon steel, cold-rolled electrical steel and special-purpose silicon steel according to the manufacturing process and use of electrical steel.
