Cold Rolled Oriented Electrical Steel

CRGO Electrical Steel

Cold rolled oriented silicon steel is 0.30 or 0.35mm thick oriented silicon steel strips, 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 strips 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 steels strips. 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 strips is used, the performance is better, and the hot-rolled strips or low-grade cold-rolled strips 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.
