Silicon Steel Coils

1.Definition: 

Silicon alloy steel with silicon content of 1.0~4.5% and 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.

2.Category:

According to the manufacturing process and use, electrical steel is divided into three categories: hot-rolled silicon steel, cold-rolled electrical steel and special-purpose silicon steel.

3.Performance characteristics: 

Silicon steel uses core loss and magnetic induction strength as the magnetic guarantee value of the product. The low loss of silicon steel saves a lot of power, extends the operating time of motors and transformers, and simplifies the cooling system. 

Silicon steel has high magnetic inductance, and the excitation current of the core is reduced, which also saves electrical energy. The high magnetic inductance of silicon steel can make the maximum magnetic inductance of the design high, the iron core is small in size, light in weight, saving silicon steel, wires, insulating materials and structural materials, etc., which not only reduces the loss and manufacturing cost of motors and transformers, but also facilitates assembly and transportation. 

In addition, silicon steel is required to have good punching and shear properties, smooth and flat surface and uniform thickness, good insulating film and small magnetic aging.
