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

     Silicon steel sheet can be divided into two types: low silicon and high silicon according to its different silicon content. Low silicon wafer contains less than 2.8% silicon, it has a certain mechanical strength, mainly used to manufacture motors, commonly known as motor silicon steel sheets.The high silicon wafer has a silicon content of 2.8%-4.8%, it has good magnetic properties, but it is brittle, and is mainly used to manufacture transformer cores, commonly known as transformer silicon steel sheets.There is no strict boundary between the two in actual use, and large motors are often manufactured with high silicon wafers.

    According to the production and processing technology, it can be divided into two types: hot rolling and cold rolling, and cold rolling can be divided into two types: grain non-oriented and oriented grain.The thickness of the cold-rolled sheet is uniform, the surface quality is good, and the magnetic property is high。Therefore, with the development of industry, hot-rolled sheets have a tendency to be replaced by cold-rolled sheets。
