(1) Hot-rolled silicon steel sheet for electrical use (GB5212-85)
The hot-rolled silicon steel sheet for electrical use is made of ferrosilicon soft magnetic alloy with low carbon loss, and is hot-rolled into a sheet with a thickness of less than 1mm. Hot-rolled silicon steel sheet for electrical use is also called hot-rolled silicon steel sheet.
Hot-rolled silicon steel sheets can be divided into low silicon (Si≤2.8%) and high silicon (Si≤4.8%) steel sheets according to their silicon content.
(2) Cold-rolled silicon steel sheet for electrical use (GB2521-88)
It is made of electrical silicon steel containing 0.8%-4.8% silicon and is cold-rolled.
Cold-rolled silicon steel sheets are divided into two types: grain-free and grain-oriented steel strips. Cold-rolled electrical steel strip has the characteristics of smooth surface, uniform thickness, high stacking coefficient, good punching performance, and has higher magnetic induction and lower iron loss than hot-rolled electrical steel strip. Using cold strips instead of hot strips to manufacture motors or transformers can reduce their weight and volume by 0%-25%. If the cold-rolled oriented strip is used, the performance is better. Using it to replace the hot-rolled strip or the low-grade cold-rolled strip can reduce the power consumption of the transformer by 45%-50%, and the working performance of the transformer is more reliable.
Used in the manufacture of motors and transformers. Generally, grain-oriented cold-rolled strips are used as the state of motors or welding transformers, etc.; grain-oriented cold-rolled strips are used as iron cores for power transformers, pulse transformers, magnetic amplifiers, and the like.
Steel plate specifications and dimensions: thickness of 0.35, 0.50, 0.65mm, width of 800-1000mm, and length of ≤2.0m.
(3) Hot-rolled silicon steel sheet for household appliances (GBH46002-90)
The grade of hot-rolled silicon steel sheet for household appliances is represented by J (home), D (electricity), and R (hot-rolled), that is, JDR. The number after JDR is the iron loss value*100, and the number after the horizontal line is the thickness of the steel plate (mm)*100. The electromagnetic performance requirements of hot-rolled silicon steel sheets for household appliances can be slightly lower, and the iron loss value (P15/50) can be as low as 5.40W/kg. Usually delivered without washing.
Differential motors used in various household appliances such as electric fans, washing machines, vacuum cleaners, range hoods, etc.
