Made in China Cold Rolled Grain Oriented Electrical 0.23mm Silicon Steel Coil For Transform

Silicon steel with a silicon content of 1.0~4.5% and a carbon content of less than 0.08% is called silicon steel. It has the characteristics of high permeability, low coercivity, and high resistivity, so the hysteresis loss and eddy current loss are small. It is mainly used as a magnetic material in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing processing when manufacturing electrical appliances, a certain plasticity is also required. In order to improve the magnetic inductance performance and reduce the hysteresis loss, the lower the content of harmful impurities, the better, and the plate shape is flat and the surface quality is good.

The requirements for the performance of silicon steel are mainly as follows:

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 (magnetic inductance) 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 weldability of the surface insulating film are good, which can prevent corrosion and improve the punching property.
