Silicon Steel

Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is a material used to produce certain magnetic cores, such as stators and rotors in transformers and motors. Electrical steel is also an indispensable material for the power, electronics and military industries.

Non-oriented electrical steelusually contains a level of 2%-3.5% silicon. It has similar magnetic properties in all directions, the so-called isotropy.

Grain-oriented electrical steelusually contains a level of 3% silicon and is processed in a way to develop ideal properties in the rolling direction. Cold-rolled non-grain-oriented steel (CRNGO) is less expensive than cold-rolled grain-oriented steel (CRGO). CRNGO can be used in cost-oriented applications with the inconstant direction of magnetic flux, such as electric motors and generators. CRGO is usually in coil form and has to be cut into laminations further, being used in transformer core applications, such as certain internal parts in audio output transformers.

Application

Silicon steel is the most important magnetic material in industrial applications. The general applications include volt relays or pulse transformers from the generator, automotive, and transformer sectors.

Features of ZLYS GO electrical steel products

Excellent electromagnetic property

first-class equipment, leading manufacturing process and strict management ensure the excellent and stable electromagnetic property of ZLYS 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

ZLYS’s leading equipment and manufacturing technology ensure good shape, smooth surface, uniform thickness, small intra-plate deviation, and high lamination factor.

Excellent surface coating property

ZLYS electrical steel has a uniform surface coating with good adhesiveness, which can prevent the peeling of the coating during processing; the interlaminar insulation property is good.

More width options

the users can choose from sheet widths of 700-1200mm of ZLYS GO electrical steel, so as to improve the utilization ratio of the material.
