Shanghai Guan You Industrial Co., Ltd. primarily deals in non-oriented and oriented silicon steel. It also handles silicon steel products from Baosteel and Wuhan Iron and Steel. The products are widely used in various industries such as automotive motors, electric motors, welding machines, power transformers, reactors, and instrument transformers. The company can also handle futures business for customers with designated steel mills.
  The company is equipped with multiple Taiwan-made silicon steel slitting and shearing equipment to ensure precise processing dimensions. There are two categories: regular material and self-adhesive, with main thicknesses including: 0.2mm  0.23mm  0.27mm  0.3mm  0.35mm 0.5mm 0.65mm  

Performance of Cold-Rolled Non-Oriented Silicon Steel:

The main requirements for silicon steel performance are:

1. Low iron loss, which is the most important indicator of silicon steel sheet quality. Grades are classified based on iron loss values in various countries; the lower the iron loss, the higher the grade.

2. High magnetic induction intensity (magnetic flux density) under strong magnetic fields, which reduces the volume and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, insulation materials, etc.

3. Smooth and flat surface with uniform thickness, improving the filling factor of the core.

4. Good punching performance, which is particularly important for manufacturing micro and small motors.

5. Good adhesion and weldability of the surface insulation film, providing corrosion resistance and improving punching performance.

Electrical steel is mainly divided into two categories: grain-oriented electrical steel and grain non-oriented electrical steel.

Grain-oriented electrical steel has easy magnetization grain directions distributed along the rolling direction, offering excellent characteristics such as high magnetic flux density, low iron loss, and low magnetostriction in the rolling direction. Additionally, through magnetic domain refinement technology, even lower iron loss performance can be achieved, making it widely used in the transformer industry.

Grain non-oriented electrical steel has randomly distributed grain directions, with uniform electromagnetic properties in all directions, making it widely used in the motor industry.
