Requirements for the performance of silicon steel

1. Low iron loss, which is the most important indicator of silicon steel sheet quality. All countries divide the grades according to the iron loss value. The lower the iron loss, the higher the grade.

2. The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the volume and weight of the iron core of motors and transformers, and saves silicon steel sheets, copper wires and insulating materials.

3. The surface is smooth, flat and uniform in thickness, which can increase the filling factor of the iron core.

4. Good punching performance, which is more important for the manufacture of miniature and small motors.

5. The surface insulation film has good adhesion and weldability, which can prevent corrosion and improve the punching property.
