Highly permeable smooth electric cold rolled silicon steel with the good weldability

    Cold-rolled silicon steel sheets are divided into two types of steel strips: grain-oriented and grain-oriented。The cold-rolled electrical 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 electrical 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 cold-rolled oriented strip is used, the performance is better。Using it instead of hot-rolled strip or low-grade cold-rolled strip can reduce the power consumption of the transformer by 45%-50%, and the transformer performance is more reliable。

     Silicon steel sheet for electrical use is commonly known as silicon steel sheet or silicon steel sheet. It is a soft magnetic alloy of ferrosilicon with very low carbon content, generally with a silicon content of 0.5~4.5%, which is made by hot and cold rolling. Generally, the thickness is less than 1mm, so it is called thin plate.
