Cold rolled grain oriented silicon steel

Cold rolled grain oriented silicon steel

Silicon steel is a soft magnetic material made of iron silicon alloy with silicon content. Its core characteristics are high electrical resistivity, low coercivity, and excellent high magnetic permeability, which can significantly reduce eddy current losses and hysteresis losses in alternating magnetic fields. Grain oriented silicon steel (such as Hi-B steel) or non oriented silicon steel can be produced through cold rolling process. The former has better magnetic properties along the rolling direction and is commonly used in transformer cores; The latter has isotropic magnetic properties and is commonly used for motor and generator rotors. The performance of silicon steel sheets is affected by silicon content, grain structure, and insulation coating. Modern technology further reduces iron loss through laser engraving or plasma treatment. Its application in the power industry directly affects the efficiency of power transmission and equipment energy consumption level.
