Cold Rolled Non Oriented Silicon Steel Electrical Steel

Cold Rolled Non Oriented Silicon Steel Product Description

---

 

Cold-rolled non-oriented electrical steel Performance

• High Electrical Resistivity: Silicon addition significantly increases the steel's resistance to electrical currents, which reduces eddy current losses and improves efficiency.
• High Magnetic Permeability: Enhances the ease with which the material can be magnetized.
• Low Core Loss: Reduces energy loss from the core material as it is subjected to a changing magnetic field.

 

CRNGO electrical steel Applications

• Electric Motors:

Their isotropic properties are ideal for the rotating parts of electric motors.

 

• Generators:

The randomly oriented grains are also well-suited for use in the magnetic cores of generators.

 

Benefits of Cold-Rolled vs. Hot-Rolled

• Superior Surface Finish and Thickness Accuracy:

Cold-rolling produces a smoother surface and more precise thickness, which improves the magnetic properties and filling factor of the finished component.

 

• Improved Magnetic Properties:

The cold-rolling process, combined with the non-oriented grain structure, leads to better energy efficiency in electrical machines compared to hot-rolled alternatives.
