Oriented silicon steel is an electrical steel with an easy magnetization direction parallel to the rolling direction and a silicon content of about 3%. Oriented silicon steel can be divided into two categories: general oriented silicon steel and high magnetic inductive oriented silicon steel, which are mostly used in the field of power transmission (such as transformers, etc.), and are indispensable important metal functional materials in the power, electronics and military industries.

In addition to the above-mentioned categories of electrical steel, there are also some special-purpose electrical steel plates: Such as 0.15 and 0.20mm thick 3%Si cold-rolled non-oriented silicon steel strips and 0.025, 0.05 and 0.1mm thick 3%Si cold-rolled oriented silicon steel strips, used as medium and high frequency motors and transformers, and pulse transformers; 0.7mm thick 3%Si high-strength cold-rolled non-oriented silicon steel sheet for relays and power switches
