High magnetic induction grain-oriented electric steel Cool rolled silicon steel

   Silicon alloy steel with a silicon content of 2.9~3.3% 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。

    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 (Bm) 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 theThe motor is made up of toothed round punches stacked into an iron core and works in the running state. The silicon steel plate is required to be magnetically isotropic and manufactured with non-oriented silicon steel. 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.
