Original 0.27mm CRGO 1020mm M4 Silicon Electrical Steel Coil Grain Oriented
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.
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).
