DESCRIPTION
Electrical steel usually referred to as cold-rolled electrical steel, can be divided into two major categories including grain-oriented electrical steel and non-oriented electrical steel. Grain-oriented electrical steel, 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. Meanwhile, non-oriented electrical steel, featured by a random distribution of grain orientation and magnetic isotropy, is widely applicable to the motor industry.
Features of GO electrical steel products
Excellent electromagnetic property
first-class equipment, leading manufacturing process and strict management ensure the excellent and stable electromagnetic property of SuperB GO electrical steel.
Outstanding processability
high accuracy dimension and excellent mechanical property are convenient for the users to slit, cut, and laminate.
Preeminent dimensional accuracy
SuperB’s leading equipment and manufacturing technology ensure good shape, smooth surface, uniform thickness, small intra-plate deviation, and high lamination factor.
Excellent surface coating property
SuperB electrical steel has a uniform surface coating with good adhesiveness, which can prevent the peeling of the coating during processing; the interlaminar insulation property is good.
More width options
the users can choose from sheet widths of 700-1200mm of SuperB GO electrical steel, so as to improve the utilization ratio of the material.
