Silicon alloy steel containing 1.0 ~ 4.5% silicon and less than 0.08% carbon is called silicon steel. It has the characteristics of high permeability, low coercivity and large resistance coefficient, 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 processing in the manufacture of electrical appliances, it is also required to have a certain 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 shape is required to be flat and the surface quality is good
Silicon steel takes core loss (referred to as iron loss) and magnetic induction intensity (referred to as magnetic induction) as magnetic guarantee values. Low silicon steel loss can save a lot of power, extend the operation time of motors and transformers and simplify the cooling system. Due to silicon steel loss caused by electricity loss accounted for 2.5% ~ 4.5% of the annual power generation, transformer iron loss accounted for about 50%, 1 ~ 100kW small motor accounted for about 30%, fluorescent lamp ballast accounted for about 15%.
