**Silicon steel** has the characteristics of a high magnetic rate, low stubborn force, and large resistance coefficients, so magnetic stagnation losses and vortex losses are small. Silicon steel is mainly used as a magnetic material in motors, transformers, electrical appliances, and electrical instruments. In order to meet the needs of punching processing when making electrical appliances, there is also a certain plasticity. In order to improve the magnetic sensing performance and reduce the stasis loss, the lower the harmful impurities in the silicon steel, the better, the plate type is flat, and the surface quality is good.

Performance Characteristics of Silicon Steel

Silicon steel uses iron core loss and magnetic induction intensity as the product magnetic guarantee value. Low silicon steel loss can save a lot of electricity, extend the operating time of the motor and transformer and simplify the cooling system.

Silicon steel has a high magnetic sensation, and the exciting current of the iron core is reduced, which also saves power. High silicon steel magnetic sense can make the designed maximum magnetic sense, small iron core volume, and lightweight, saving silicon steel, wires, insulating materials, structural materials, etc., which not only reduces the loss and manufacturing cost of motors and transformers but also facilitate assembly and transportation. In addition, silicon steel is required to have good punching, smooth and smooth surface and uniform thickness, small insulating membrane, and magnetic timing.

Performance Requirements of Silicon Steel

The requirements for the performance of silicon steel are mainly:
1. Low iron loss, this is the most important indicator of the quality of silicon steel sheets.
2. High magnetic induction strength under the strong magnetic field, which reduces the volume and weight of the iron core of the motor and transformer, and saves silicon steel sheets, copper wires, and insulation materials.
3. The surface is smooth, flat, and uniform, which can increase the filling coefficient of the iron core.
4. The adhesion and welding of the surface insulation membrane can prevent corrosion and improve the punching properties.
