Types Of Silicon Steel Sheet

　　(A) Hot-rolled silicon steel sheet for electrical use (GB5212-85)

　　Electrical hot-rolled silicon steel sheet with a low carbon loss of silicon and iron soft magnetic alloy for the material, hot-rolled into a thickness of less than 1mm thin plate. Hot-rolled silicon steel sheet for electrical use is also known as 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%) according to their silicon content.

　　(B) cold-rolled silicon steel sheet for electricians (GB2521-88)

　　With silicon 0.8%-4.8% of electrical silicon steel as material, cold-rolled from.

　　Cold-rolled silicon steel sheet is divided into grain non-oriented and grain-oriented two kinds of steel strip. Cold-rolled electrical steel strip has a flat surface, uniform thickness, high stacking factor, good punchability and other characteristics, and higher magnetic inductance and lower iron loss than hot-rolled electrical steel strip. With cold-rolled strip instead of hot-rolled strip manufacturing motor or transformer, its weight and volume can be reduced by 0%-25%. If the cold-rolled oriented strip is used, the performance is better, and it replaces the hot-rolled strip or low-grade cold-rolled strip, which can reduce the transformer power consumption by 45%-50%, and the transformer work performance is more reliable.

　　Used in the manufacture of motors and transformers. Generally, grain-free cold-rolled strip is used as the state of motors or welding transformers, etc.; grain-oriented cold-rolled strip is used as the core of power transformers, pulse transformers and magnetic amplifiers, etc.

Steel plate specification size: thickness of 0.35, 0.50, 0.65mm, width of 800-1000mm, length of ≤ 2.0m.

　　(C) hot-rolled silicon steel sheet for household appliances (GBH46002-90)

　　Hot-rolled silicon steel sheet for home appliances with the grade J (home) D (electric) R (hot-rolled), that is, JDR. JDR after the number of iron loss value * 100, the number after the horizontal line for the thickness of the plate (mm) * 100. hot-rolled silicon steel sheet for home appliances can be a little lower electromagnetic performance requirements, iron loss value (P15/50) the minimum value of 5.40W/kg. generally not with the wash delivery.

　　Used for various electric fans, washing machines, hoovers, range hoods and other household appliances such as differential motors. and delivered after acid washing.
