Silicon steel coil, also known as electrical steel coil. One is the silicon content is about 0.5%~5%, the other is mainly ferrosilicon ferroalloy. It is an indispensable soft magnetic alloy in electric power, electronics and military industry. It is also a metal functional material with a large production rate. It is mainly used as the core of various motors, generators and transformers. There are mainly cold rolled unoriented silicon steel coil, cold rolled oriented silicon steel coil, high magnetic cold rolled oriented silicon steel coil.
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. Oriented silicon steel: It has strong directionality, the lowest iron loss value in the rolling direction, the highest magnetic permeability, and a higher magnetic induction value under a certain magnetization field. The silicon content of oriented silicon steel is about 3%. It also requires a low content of oxide inclusions in the steel and must contain certain inhibitors (MnS, A1N).
