CRNO Non-oriented silicon steel

application Details

grain oriented silicon steel

Silicon steel/electrical steel, usually refers to cold-rolled silicon steel/electrical steel, which can be divided into two categories: grain-oriented silicon steel/electrical iron and non-oriented silicon steel/silicon steel. Oriented silicon steel/electrical steel has been widely used in the musical instrument industry due to its easy magnetization direction parallel to the rolling direction and excellent magnetic properties such as low iron loss, high magnetic permeability and low magnetostriction. Through refinement, lower core losses can be obtained. Non-oriented silicon steel/electrical steel has the characteristics of random grain orientation distribution and magnetic isotropy, and is widely used in the motor industry.

Non-oriented silicon steel is a ferrosilicon alloy with very low carbon content. In the steel plate after deformation and annealing, the grains are distributed in random orientation.

Electrical Steel Features
1. Magnetic properties: The magnetic properties of this product are characterized by low iron loss, high magnetic permeability and good application performance.
2. Thickness tolerance: The thickness difference parallel to the rolling direction is very small, the thickness difference perpendicular to the rolling direction is also very small, and the lamination coefficient is high.
3. Processing performance: This product is suitable for stamping and cutting, with excellent dimensional tolerances
4. Insulating coating: The insulating coating has small color deviation, good adhesion, excellent heat resistance and corrosion resistance, and high electrical conductivity. There are several types of insulating coatings available for production. After testing by a professional testing agency, the content of harmful substances complies with current international and Chinese environmental regulations such as EU ROHS and REACH.
