COLD-ROLLED ORIENTED SILICON STEEL

Refers to cold-rolled electrical steel containing 2.9% to 3.5% Si, with a certain regularity and direction of the steel plate crystal structure.

Oriented silicon steel, also known as cold-rolled transformer steel, is an important ferrosilicon alloy used in the transformer (iron core) manufacturing industry. The most widely used oriented silicon steel is mostly supplied in the form of strips and coils, and its surface is coated with an insulating layer to generate tensile stress in the base steel strip, thereby further reducing the iron loss value. The surface of the cold-rolled strip is smooth, with good punching performance and high core filling factor.
