High quality cold-rolled grain oriented silicon steel sourced from Tianjin factory

Silicon steel is an important electrical material, which is widely used in electric equipment, such as motors, transformers, and generators.

The main quality characteristics of silicon steel are iron loss value, magnetic flux density, hardness, flatness, thickness uniformity and coating film.

1. Iron loss value

Low iron loss, which is the most important indicator of the quality of silicon steel. Countries classify grades according to the value of iron loss, and the lower the iron loss, the higher the grade.

2. Magnetic flux density

Magnetic flux density is another important electromagnetic property of silicon steel , which indicates how easily silicon steel are magnetized. The magnetic flux per unit area at a specific frequency is called magnetic flux density.The higher the magnetic flux density, the greater the magnetic flux per unit area, and the better the energy efficiency.

3. Hardness

Hardness is one of the quality characteristics of silicon steelgenerally, the more silicon content is added to high-grade silicon steel, the higher the hardness of the alloy solution strengthening effect.

4. Flatness

Flatness is an important quality property of silicon steel. Good flatness is conducive to punching and assembly work.

5. Thickness uniformity

Thickness uniformity is a very important quality characteristic of silicon steel . Therefore, the smaller the variation in the thickness of silicon steel, the better.

6. Coating film

Coating film is a very important quality item of silicon steel. The surface of the silicon steel is chemically coated with a thin film that provides insulation, rust protection and lubrication. The insulation reduces the eddy current loss between the silicon steel core laminations. Anti-rust to avoid rusting of steel during processing and storage; Lubricity can improve the punchability of silicon steel and increase the life of the mold.
