Electrical steel (silicon steel coil) is mainly divided into two categories: grain-oriented electrical steel and grain non-oriented electrical steel. The direction of easy magnetization grains of oriented electrical steel is distributed along the rolling direction. The rolling direction has excellent characteristics such as high magnetic induction, low iron loss and low magnetostriction. At the same time, it can also be processed by magnetic domain refinement technology to obtain lower iron Loss of performance, widely used in the field of transformer industry. The grain direction of non-oriented electrical steel is randomly distributed, and the electromagnetic properties are uniform in all directions. It is widely used in the motor industry.

        Silicon steel with silicon content of 1.0 ~ 4.5% and carbon content less than 0.08% are called silicon steels. It has the characteristics of high permeability, low coercivity and high 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, certain plasticity is required. In order to improve the magnetic inductive energy and reduce the hysteresis loss, the harmful impurity content should be as low as possible, and the plate type should be flat and the surface quality should be good.
