SILICON STEEL FOR TRANSFORMER CORES

Silicon Steel Performance Requirements:

1. Low iron loss, which is the most important indicator of the quality of silicon steel sheet. Countries classify grades according to the value of iron loss, and the lower the iron loss, the higher the grade.

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

3. The surface is smooth, flat and uniform in thickness, which can improve the filling coefficient of the core.

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

5. The adhesion and weld ability of the surface insulating film are good, which can prevent corrosion and improve the punching property.
