The magnetism of oriented silicon steel has strong directionality, which has the lowest iron loss value, the highest permeability and high magnetic induction value under a certain magnetization field.

Cold rolled silicon steel has the characteristics of smooth surface, uniform thickness, high stacking coefficient and good punching property, and has higher magnetic induction and lower iron loss than hot rolled silicon steel. Using cold rolled silicon steel instead of hot rolled silicon steel to manufacture motor or transformer can reduce its weight and volume by 0%-25%. If cold rolled oriented silicon steel is used, its performance will be better. Using it instead of hot rolled silicon steel or low-grade cold rolled silicon steel can reduce the power consumption of transformer by 45%-50%, and the working performance of transformer is more reliable.
