Cold-rolled oriented silicon steel
 

Cold rolled silicon steel sheet is divided into two kinds of grain orientation and grain orientation steel strip. Generally, the grain non-oriented cold rolled strip is used as an iron core for motors or welding transformers. Grain oriented cold rolled strip is used as the core of power transformers, pulse transformers and magnetic amplifiers.
Cold rolled oriented thin silicon steel strip is 0.30 or 0.35mm thick oriented silicon steel strip, and then pickling, cold rolling and annealing made. Cold rolled non-oriented silicon steel sheet is the billet or continuous casting billet hot rolled into a thickness of about 2.3mm coil. The cold-rolled silicon steel strip has the characteristics of flat surface, uniform thickness, high stacking coefficient, good punching property, and higher magnetic induction and lower iron loss than the hot-rolled silicon steel strip. By using cold strips instead of hot rolled strips to manufacture motors or transformers, the weight and volume can be reduced by 0-25%. If the cold-rolled orientation strip is used, the performance is better, and the hot-rolled strip or low-grade cold-rolled strip is replaced by it, the power consumption of the transformer can be reduced by 45%-50%, and the working performance of the transformer is more reliable.
