An introduction of silicon steel

Silicon alloy steel with a silicon content of 1.0 to 4.5% and a carbon content of less than 0.08% is called silicon steel. The lower the iron loss value, the better the quality of the iron; generally, the weight of a silicon steel coil is about 3-4 tons. It has the characteristics of high permeability and large resistivity, 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 the hysteresis loss, it is required that the content of harmful impurities is as low as possible, and the plate shape is required to be flat and the surface quality is good.
