Silicon steel sheet performance index
A. Low iron loss. An important indicator of quality, all countries in the world divide grades by iron loss value. The lower the iron loss, the higher the grade and the higher the quality.
B. high magnetic induction intensity. Under the same magnetic field, a silicon steel sheet with higher magnetic induction can be obtained, and the volume and weight of the motor or transformer iron core made by it are relatively small, which can relatively save silicon steel sheet, copper wire and insulating materials.
C. the stacking coefficient is high. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, and the stacking coefficient of the iron core is improved.
D. Good punchability. This is even more important for the manufacture of small, miniature motor cores.
E. The surface has good adhesion and weldability to the insulating film.
F. Magnetic aging.
G. The silicon steel sheet shall be delivered after annealing and pickling.
