High Quality Factory Price silicon steel Ei Transformer Lamination
There are roughly 2 types of silicon steel sheets seen on the market:
1. According to the production and processing technology, it can be divided into hot rolling and cold rolling, and cold rolling can be divided into grain non-oriented and grain oriented. Cold rolled sheet has uniform thickness, good surface quality, and high magnetic properties. Therefore, with the development of industry, hot rolled sheet tends to be replaced by cold rolled sheet (China has clearly requested to stop using hot rolled silicon steel sheet, which is what was said in the previous period "Replace heat with cold").
2. 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, it has a certain mechanical strength, and is mainly used for manufacturing motors, commonly known as motor silicon steel sheets; the high silicon wafer has a silicon content of 2.8% -4.8%, which has good magnetic properties, but is relatively brittle, and is mainly used For 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 chips are commonly used to manufacture large motors.
