Product Description China Professional Supplying 0.23mm 0.27mm 0.3mm Cold Rolled Grain Oriented Silicon Steel Coil CRGO/NonC-Oriented Electrical Steel Sheet For Transformer Product DescriptionSilicon Steel General Introduction:Electical steel(Silicon Steel), usually referring to cold rolled electrical steel. Cold rolled electrical steel is an essential soft magnetic material used as the core material for making various electrical appliances such as motors and transformers. Electrical steel is the most commonly used soft magnetic material and is widely used in the electrical power, electronics and military industries. On one hand, it is closely related to people' production, life and other daily activities, on the other hand, it has also made great progress in adapting to the progress of the times. It can be divided intotwo major categories including grain oriented silicon steel and non-oriented electrical steel. CRGO silicon steel is a soft magnetic material produced using a cold rolling process and it is designed to have uniform magnetic properties in all directions.With its easy magnetization direction parallel to the rolling direction,has excellent magnetic properties in this direction including low core loss, high permeability and low magnetostriction and is widely used in the transformer industry. Further it can obtain lower core loss by domain refinement treatment. Cold Rolled Grain-Oriented Electrical Steel (GOES) is a soft magnetic material that produced using a cold rolling process. Its grain orientation inside the steel plate is consistent with the longitudinal direction (rolling direction) of the strip. GOES is mainly used for production of various transformers and the transformers core is made of a stack of GOES lamination.Meanwhile non-oriented electrical steel,featured by random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry. 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.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).
