Bobina de oțel electric neorientată

Non-oriented silicon steel is mainly used in household appliances, industrial field motors, large motors, new energy vehicles and other fields.

The silicon, aluminum and manganese content of steel is controlled in a certain range according to regulations, and the carbon, sulfur, nitrogen and oxygen content is as low as possible. Different grades have different requirements for the content of these elements. Aluminum improves the strength and hardness of electrical steel and reduces ductility. However, the effect of aluminum on reducing ductility is not as pronounced as silicon, and the role is similar to silicon. Therefore, as the grade increases, the silicon content increases to about 3% without further change, and the aluminum content can be gradually increased to 1%. General grade aluminum content of 0.3% to 0.6%. With the grade increase, carbon, sulfur and manganese content is further reduced. High grade impurity content is: S <0.002%, C <0.003%, N2 <0.002%, O2 <0.002%, later annealed without decarburization, to prevent the formation of internal oxidation layer and internal nitrided layer. In addition, Ti<0.005% and Zr<0.002% are required to prevent the formation of fine TiN, ZrN and TiC, which hinder grain growth.
