Classification of silicon steel sheets for induction melting furnaces
A. 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, which has a certain mechanical strength and is mainly used for the manufacture of electric motors, commonly known as intermediate frequency furnace or motor silicon steel sheet; , mainly used in 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 wafers are often used to manufacture large motors.
B. 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: non-oriented grain and grain oriented. Cold-rolled sheets have uniform thickness, good surface quality, and high magnetic properties. Therefore, with the development of the industry, hot-rolled sheets tend to be replaced by cold-rolled sheets (my country has clearly requested that the use of hot-rolled silicon steel sheets be stopped, which is what was said earlier. “replacing heat with cold”).
