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

Cold Rolled Silicon Steel Coil Features
The magnetic induction of silicon steels is high, the excitation current of the iron core is reduced, and the electric energy is also saved. The high magnetic induction of silicon steels can make the maximum magnetic induction (Bm) of the design high, the iron core is small in size and light in weight, saving silicon steel, wires, insulating materials and structural materials, etc., which not only reduces the loss and manufacturing cost of the motor and transformer, but also facilitates assembly and transport. The motor, which is stacked with toothed circular punches to form an iron core, works in a running state. The silicon steels plate is required to be magnetically isotropic and made of non-oriented silicon steels. The transformer, which consists of strips stacked into an iron core or strips wound into an iron core, works in a static state and is made of cold-rolled oriented silicon steels with large magnetic anisotropy. In addition, silicon steels is required to have good punching and shearing properties, smooth surface and uniform thickness, good insulating film and small magnetic aging.
