Classification of silicon steel sheet

1. Silicon steel sheets can be divided into low silicon and high silicon according to their silicon content. The low silicon wafer contains less than 2.8% silicon, it has a certain mechanical strength, and is mainly used for manufacturing motors, commonly known as motor silicon steel sheets; the high silicon wafer has a silicon content of 2.8% -4.8%. For the manufacture of transformer cores, commonly known as transformer silicon steel sheets. There is no strict boundary between the two in actual use, and high-silicon chips are commonly used to manufacture large motors.

Second, according to the production and processing technology, it can be divided into hot rolling and cold rolling, and cold rolling can be divided into grain non-oriented and grain oriented. Cold rolled sheets have uniform thickness, good surface quality and high magnetic properties. Therefore, with the development of industry, hot rolled sheets tend to be replaced by cold rolled sheets. "Replace heat with cold").
