Electrical steel (silicon steel coil)

Electrical steel (silicon steel coil) is mainly divided into two categories: grain-oriented electrical 

steel and grain non-oriented electrical steel. The direction of easy magnetization grains of 

oriented electrical steel is distributed along the rolling direction. The rolling direction has excellent 

characteristics such as high magnetic induction, low iron loss and low magnetostriction. At the 

same time, it can also be processed by magnetic domain refinement technology to obtain lower 

iron Loss of performance, widely used in the field of transformer industry. The grain direction of 

non-oriented electrical steel is randomly distributed, and the electromagnetic properties are 

uniform in all directions. It is widely used in the motor industry.

The difference between oriented silicon steel and non-oriented silicon steel Non-oriented silicon 

steel: ferrosilicon alloy with very low carbon content. In the deformed and annealed steel sheet, its 

grains are distributed randomly. The silicon content of the alloy is 1.5% to 3.0%, or the sum of the 

silicon and aluminum content is 1.8% to 4.0%. The products are usually cold-rolled plates or strips, 

which are mainly used to manufacture motors and generators.

Non - oriented silicon steel sheet is hot rolled billet or continuous casting billet into a thickness of 

about 2.3mm coil. For low-silicon products, hot rolled rolls are cold rolled to 0.5mm thick after pickling. 

For the manufacture of high silicon products, after pickling in hot rolling (or after normalizing at 800 ~ 

850℃ and then pickling), cold rolled to 0.55 or 0.37mm thick, annealed at 850℃ in a continuous furnace 

with hydrogen and nitrogen mixture atmosphere, and then cold rolled to 0.50 or 0.35mm thick at a low 

reduction rate of 6 ~ 10%. The small reduction rate of cold rolling can make the grain grow and the iron 

loss decrease during annealing. Both cold rolled sheets are finally annealed at 850℃ in a continuous 

furnace in a 20% hydrogen nitrogen mixture atmosphere, and then coated with phosphate and chromate 

insulating film. After cold rolling to the thickness of the finished product, the supply of 0.35mm and 0.5mm 

thick steel strip. The Bs of cold rolled non - oriented silicon steel is higher than that of oriented silicon steel.
