China Factory of Silicon Steel Sheet Cold Rolled Silicon Steel Coil

(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 wafers contain less than 2.8% silicon. They have a certain mechanical strength and are mainly used to make motors, commonly known as motor silicon steel sheets. High silicon wafers contain 2.8%-4.8% silicon. They have good magnetism but are brittle and are mainly used for Used in manufacturing 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 commonly 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. Cold rolling can be divided into two types: 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 have a tendency to be replaced by cold-rolled sheets (our country has clearly required the discontinuation of the use of hot-rolled silicon steel sheets, which is what was previously called "Replacing heat with cold").
