COLD ROLLED GRAIN ORIENTED SILICON STEEL

CRGO SILICON STEEL:

Cold-rolled silicon steel sheets are divided into two types of steel strips: grain-oriented and grain-oriented. In general, grain-oriented cold-rolled strip is used as the core of motors or welding transformers, etc., and grain-oriented cold-rolled strip is used as the core of power transformers, pulse transformers, magnetic amplifiers, etc. Cold rolled oriented thin silicon steel strip is made of 0.30 or 0.35mm thick oriented silicon steel strip and then pickled, cold-rolled and annealed. The cold-rolled non-oriented silicon steel sheet is hot rolled into a strip coil with a thickness of about 2.3mm from billet or continuous casting billet. Cold-rolled silicon steel strip has the characteristics of flat surface, uniform thickness, high stacking coefficient and good punching ability, and has higher magnetic inductance and lower iron loss than hot-rolled silicon steel strip. Using cold strip instead of hot rolled strip to manufacture motors or transformers can reduce their weight and volume by 0%-25%. If the cold-rolled oriented strip is used, the performance is better, and it can be used instead of hot-rolled strip or low-grade cold-rolled strip, which can reduce the power consumption of the transformer by 45%-50%, and the working performance of the transformer is more reliable.
