Product Description

Product Name: Oriented silicon steel

 

Silicon steel is a silicon-iron alloy with a silicon content of about 3% and the others are mainly iron. It is an indispensable
and important soft magnetic alloy in the power, electronics and military industries, and it is also the metal
functional material with the largest output. It is mainly used as the iron core of various motors,
generators and transformers. Its production process is complex, the manufacturing
technology is strict, and the foreign production technology is protected in the form of patents,
which is regarded as the life of the enterprise.

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 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, it also requires a certain degree of plasticity. In order to improve magnetic susceptibility and reduce hysteresis loss, the content of harmful impurities is required to be as low as possible, and the plate type is smooth and the surface quality is good.


Performance Requirement:
 

The main requirements for the performance of silicon steel are:

1. Low iron loss, which is the most important indicator of the quality of silicon steel sheet. Countries are divided according to the value of iron damage, the lower the iron damage, the higher the brand.

2, strong magnetic field under the magnetic induction intensity (magnetic sensation) is high, which makes the motor and transformer core volume and weight reduction, saving silicon steel sheet, copper wire and insulation materials.

3, the surface is smooth, smooth and uniform thickness, can improve the filling coefficient of the iron core.

4. Good punching property, which is more important for the manufacture of miniature and small motor.

5, the surface insulation film adhesion and weldability is good, can prevent corrosion and improve the punching property.

Manufacturing Technique
 

1.Pickling

The oxide of hot-rolled steel strip is removed by descaling machine and salt and acid tank to prevent surface defects of cold-rolled products.

2.Cold stamping

In order to ensure the thickness and material of different uses, the deceleration ratio is set at 40%-90%, and to achieve automatic thickness control, automatic shape control and other advanced control equipment.

3.Annealing

It is to soften the hardened steel strip in cold stamping engineering. Through metal heating and rapid cooling, deep processing steel and high tensile steel are produced, and packing (cover annealing) and continuous annealing method.

4.Insulating coating

When the silicon steel plate is processed into iron core, in order to improve its machining performance and prevent the eddy current loss equivalent to the thickness of the steel plate, continuous coating equipment is used to spray insulation coating liquid on the bottom of the steel plate
