Silicon steel contains 1.0 to 4.5% silicon and silicon alloy steel with a carbon content of less than 0.08% is called silicon steel.
Silicon steel is a ferrosilicon alloy. Sheets rolled from silicon steel are the most widely used soft magnetic materials in the electrical field, so silicon steel sheets are also called electrical steel sheets.
Silicon steel is widely used in motors, generators, transformers, chokes, electromagnetic mechanisms, relays and measuring instruments.
The thermal conductivity is 191W/K*m. Silicon alloy steel containing 1.0 to 4.5% silicon and less than 0.08% carbon is called silicon steel. It has the characteristics of high magnetic permeability, low coercivity, large resistivity, etc. The thermal conductivity is 191W/K*m, so the hysteresis loss and eddy current loss are small. Mainly used as magnetic materials in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing when manufacturing electrical appliances, a certain degree of plasticity is also required.
In order to improve the magnetic induction performance and reduce hysteresis loss, the content of harmful impurities is required to be as low as possible, and the plate shape is required to be smooth and the surface quality is good.
