DESCRIPTION
Electrical steel is a soft magnetic material with enhanced electrical properties that is widely used across applications such as small relays, solenoids, electric motors, generators, and many other electromagnetic devices. Electrical steel is also referred to as silicon steel, transformer steel, or lamination steel. It is used mainly in electrical power distribution systems and in automotive industries.
Classification of electrical steel
Category | Silicon content, % | Nominal thickness, mm | ||
Hot rolled silicon steel plate
(no orientation) |
Hot-rolled low-silicon steel (hot-rolled electrical steel) | 1.0~2.5 | 0.50 | |
Hot-rolled high-silicon steel (hot-rolled transformer steel) | 3.0~4.5 | 0.35 and 0.50 | ||
Cold rolled electrical steel sheet | Non-oriented electrical steel
(cold-rolled electrical steel) |
Low carbon electrical steel | ≤0.5 | 0.50 and 0.65 |
Silicon steel | >0.5~3.2 | 0.35 and 0.50 | ||
Oriented silicon steel
(cold-rolled transformer steel) |
Ordinary grain oriented silicon steel | 2.9~3.3 | 0.20,0.23,0.27
0.30 and 0.35
|
|
High magnetic induction oriented silicon steel | 2.9~3.3 |
In addition to the types of electrical steel in the above table, there are also some electrical steel sheets for special purposes, such as 0.15 and 0.20mm thick 3%Si cold-rolled non-oriented silicon steel strips and 0.025, 0.05 and 0.1mm thick 3%Si cold-rolled oriented silicon steel thin strips. 0.7mm thick 3% Si high-strength cold-rolled non-oriented silicon steel plate for relays and power switches; high-strength cold-rolled electrical steel plate for new high-speed motor rotors ; Low-carbon electrical steel hot-rolled thick plates and cold-rolled plates for magnetic shielding of medical nuclear magnetic resonance tomography scanners and high-energy accelerator electromagnets; 4.5%~6.5% Si high-silicon steel plates for high-frequency motors and transformers, and magnetic shielding, etc. .
