Detailed introduction
Silicon Steel
Silicon steel, also known as electrical steel, silicon electrical steel, lamination steel, relay steel, or transformer steel is specialty steel with silicon added to it, which improves its electrical resistivity and magnetic properties, and reduces hysteresis loss. This steel is ideal for various electrical applications where electromagnetic fields are important, such as transformers, magnetic coils, and electrical motors.
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 Taigang Puxin GO electrical steel products
Excellent electromagnetic property
first-class equipment, leading manufacturing process and strict management ensure the excellent and stable electromagnetic property of Taigang Puxin 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
Taigang Puxin’s leading equipment and manufacturing technology ensure good shape, smooth surface, uniform thickness, small intra-plate deviation, and high lamination factor.
