High Silicon Contents And Magnetism With Uniform Surface Quality And Good Shearing CRGO

   Silicon steel sheet can be divided into two types: low silicon and high silicon according to its different silicon content. Low silicon wafer silicon content is less than 2.8%, it has a certain mechanical strength, mainly used in the manufacture of motors, commonly known as motor silicon steel sheet, high silicon wafer silicon content of 2.8%-4.8%, it has good magnetic properties, but brittle, mainly used in the manufacture of transformer core, commonly known as transformer silicon steel sheet. There is no strict boundary between the two in actual use, and large motors are often manufactured with high silicon wafers. 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: grain no orientation and grain orientation. 

   The thickness of the cold-rolled sheet is uniform, the surface quality is good, and the magnetic property is high, therefore, with the development of industry, the hot-rolled sheet has a tendency to be replaced by the cold-rolled sheet (China has clearly required the cessation of the use of hot-rolled silicon steel sheet, which is the "cold instead of heat" in the early stage).
