Difference between silicon steel sheet and silicon steel sheet

Silicon steel sheets

Silicon steel sheet for electrical purposes is commonly known as silicon steel sheet or silicon steel sheet. Wangwen Shengyi is an electrical silicon steel with silicon content as high as 0.8%-4.8%. It is made by hot and cold rolling. Generally, the thickness is less than 1 mm, so it is called thin plate. Silicon steel sheet belongs to the category of sheet in a broad sense, and it is an independent branch because of its special use.

Silicon steel sheet for electrical purposes has excellent electromagnetic function and is an important magnetic material that can not be lacked in power, telecommunications and surface industry.

(1) Classification of silicon steel sheets

A. Silicon steel sheets can be divided into low silicon and high silicon according to their silicon content. Low silicon wafer contains less than 2.8% silicon, which has a certain mechanical strength. It is mainly used to manufacture motor, commonly known as silicon steel sheet of motor. High silicon wafer contains 2.8% - 4.8% silicon, which has good magnetism, but is brittle. It is mainly used to manufacture transformer core, commonly known as transformer silicon steel sheet. There is no serious gap between them in practical use. Large motors are usually made of high silicon wafers. B. According to the production process, it can be divided into hot rolling and cold rolling, and cold rolling can be divided into two kinds: grain orientation and non-orientation. 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 (China has explicitly requested that the use of hot-rolled silicon steel sheets should be stopped, that is to say, "cold-rolled sheets should be replaced by hot-rolled sheets".
