What is the material of the silicon steel sheet used in the transformer core

- Aug 05, 2019-

Silicon steel sheets for electricians are commonly known as silicon steel sheets or silicon steel sheets. As its name suggests, it is an electrical silicon steel containing up to 0.8% to 4.8% silicon, which is hot and cold rolled. Generally, the thickness is less than 1 mm, so it is called a thin plate. Silicon steel sheets are broadly referred to as sheet metal and are independent of one branch due to its special purpose. Silicon steel sheets for electricians have excellent electromagnetic properties and are indispensable important magnetic materials in the power, telecommunications and instrumentation industries.


Classification of silicon steel sheets


A. Silicon steel sheets can be classified into low silicon and high silicon according to their silicon content. Low silicon wafer contains less than 2.8% silicon, it has a certain mechanical strength, mainly used in the manufacture of motors, commonly known as motor silicon steel sheets; high silicon wafers contain 2.8%-4.8% silicon, which has good magnetic properties, but is brittle, mainly used In the manufacture of transformer core, commonly known as transformer silicon steel sheet. There is no strict limit between the two in actual use, and high-silicon wafers are often used to manufacture large motors.


  B. According to the production and processing technology, it can be divided into hot rolling and cold.
