Description of Silicon Steel Sheet
Transformer silicon lamination steel core is a very low carbon ferrosilicon soft magnetic alloy, generally contains 0.5 ~ 4.5% silicon. The addition of silicon can improve the resistivity and maximum permeability of iron, and reduce coerce, core loss and magnetic aging.
Application of Silicon Steel Sheet
The silicon lamination can be used to make core of transformer and motor.
Performance Requirements of Silicon Steel Sheet
The performance requirements of silicon steel are mainly as follows: (1) Low iron loss, which is the most important index of silicon steel sheet quality. Many countries have grades based on iron loss values. The lower the iron loss, the higher the grade. (2) High magnetic induction intensity (magnetic induction) under strong magnetic field, which makes the motor and transformer core volume and weight reduce, saving silicon steel, copper wire and insulation materials. (3) Smooth surface, flat and uniform thickness can improve the core filling coefficient. (4) Good punching is more important for the manufacture of micro, small motor. (5) The surface insulation film has good adhesion and weldability, which can prevent corrosion and improve the punching property. (6) Basically no magnetic aging.
