Hot-rolled silicon steel sheets for electricians are made of ferrosilicon soft magnetic alloy with low carbon loss, and are hot-rolled into sheets with a thickness of less than 1mm. Hot-rolled silicon steel sheets for electrical purposes are also called hot-rolled silicon steel sheets.
Hot-rolled silicon steel sheets can be divided into two types: low silicon (Si ≤ 2.8%) and high silicon (Si ≤ 4.8%) according to their silicon content.
Cold-rolled silicon steel sheet for electrical purposes (GB2521-88)
It is made of electrical silicon steel containing 0.8%-4.8% silicon and is made by cold rolling.
Cold-rolled silicon steel strips are divided into two types: grain-non-oriented and grain-oriented steel strips. Cold-rolled electrical steel strip has the characteristics of smooth surface, uniform thickness, stacking coefficient, punching performance, etc. It has higher magnetic induction and lower iron loss than hot-rolled electrical steel strip. Using cold strip instead of hot-rolled strip to manufacture motors or transformers can reduce the weight and volume by 0%-25%. If cold-rolled oriented strip is used, it has good performance. Using it instead of hot-rolled strip or cold-rolled strip can reduce the power consumption of the transformer by 45%-50%, and the transformer has reliable working performance.
Used in the manufacture of motors and transformers. Generally, grain-non-oriented cold-rolled strips are used as motors or welding transformers, etc.; grain-oriented cold-rolled strips are used as iron cores for power transformers, pulse transformers, magnetic amplifiers, etc.
Differential motors used in various electric fans, washing machines, vacuum cleaners, range hoods and other household appliances.
