Performance indicators of silicon steel sheets:

A、 Low iron loss. The more important indicator of quality is that countries around the world classify trademarks based on iron loss values. The lower the iron loss, the higher the trademark and the higher the quality.

B、 High magnetic induction intensity. Silicon steel sheets that can achieve higher magnetic induction under the same magnetic field can be used to manufacture motor or transformer cores with smaller volume and weight, which can relatively save silicon steel sheets, copper wires, and insulation materials.

C、 The stacking coefficient is high. The surface of silicon steel sheets is lubricated, flat, and of uniform thickness, which increases the stacking coefficient for manufacturing iron cores. D、 Good flushing performance. This is even more important for manufacturing small and micro motor iron cores.

E、 The adhesion and weldability of the insulation film on the surface are outstanding.

F、 Magnetic aging

G、 Silicon steel sheets must be delivered after annealing and acid washing.

Siliconsteel sheets are a type of soft magnetic alloy made of silicon iron with extremely low carbon content, typically ranging from 0.5% to 4.5% silicon. Participating in silicon can increase the electrical resistivity and magnetic permeability of iron, reduce coercivity, iron core loss (iron loss), and magnetic aging. Mainly used to make iron cores for various transformers, motors, and generators. The global output value of silicon steel sheets accounts for about 1% of the total steel production (see precision alloys).

The primary requirements for the performance of silicon steel are:

① Low iron loss is a more important indicator of the quality of silicon steel sheets. Each country classifies trademarks based on the value of iron loss, with lower iron loss indicating higher trademark value.

② Under strong magnetic fields, the magnetic induction intensity (magnetization) is high, which reduces the volume and weight of the iron core of motors and transformers, saving silicon steel sheets, copper wires, and insulation materials.

③ The surface is lubricated, flat, and of uniform thickness, which can improve the filling coefficient of the iron core.

④ Good punching performance is more important for manufacturing micro and small electric motors.

⑤ The adhesion and weldability of the external insulation film are outstanding, which can prevent corrosion and improve the punching performance.

⑥ Basically non-magnetic aging.
