What Is The Use Of Silicon Steel?

Purpose of oriented silicon steel:
An important soft magnetic material in the military and electronic industries, mainly used as high-frequency transformers, high-power magnetic amplifiers, pulse generators, universal yoke coils, inductors, storage and memory components, switches and control components, magnetic shielding, and transformers operating under vibration and radiation conditions. Compared with other materials such as ferrite and amorphous materials, the 3% Si -- Fe thin strip has high saturation magnetic induction and permeability, which can make the iron core very small. Due to its cold rolled strip, it has a flat surface, small difference in the same plate, good shape, and good processing performance. It can be made into various shapes and specifications of iron cores such as CD type, ring type, and rectangular type. It has a wide range of applications and a wide frequency range (50H-20KH).

The purpose of hot-rolled silicon steel:
Hot rolled Electrical steel is mainly used for some small motors, micro motors, such as some low-quality washing machines, fume exhausters, and some high specification low-efficiency motors can be used for hot rolled 450.
The use of cold rolled non oriented silicon steel:
The motor is basically made of non oriented silicon steel. Gap type motors (water pumps) mainly use cold rolled non oriented and uncoated silicon steel for welding machines. There are two types of motors: DC motors and AC motors. DC motors can use uncoated cold rolled silicon steel, while AC motors mainly use coated 600 non oriented silicon steel.
Motors for air compressors and air pumps can also use uncoated cold-rolled silicon steel.
The micro and special motors used in Small appliance mainly use non oriented 470. The main motor used in CNC machine tools is 470. The main motors used for air conditioning compressors are 600, 800, 1000, and 1300, depending on the requirements of the air conditioning manufacturer. Generally, the higher the brand, the higher the quality of the air conditioning.
Refrigerator motors: high-quality ones use 350, high-quality ones use 470, and ordinary manufacturers mainly use high-grade ones like 600 (Baosteel, Zhonggang, Posco).

Silicon steel occupies a very important position in the electrification construction. In a sense, the amount of silicon steel sheets used in a country can measure the degree of electrification in that country. Therefore, in the long run, Electrical steel has great prospects for development. At present, Electrical steel is developing in the direction of replacing heat with cold, and cold rolled silicon steel is developing in the direction of high grade, low iron loss, low grade and high magnetic induction.
