    CRGO Cold Rolled Silicon Steel Coil For Transformer

    Cold rolled oriented silicon steel, also known as cold rolled transformer steel, is an important ferrosilicon alloy used in transformer (core) manufacturing industry. Its production process is complex and its manufacturing technology is strict. It is mainly divided into ordinary oriented silicon steel (CGO) and high magnetic induction oriented silicon steel (HiB).

    Cold rolled non oriented silicon steel is a ferrosilicon alloy with low carbon content. In the deformed and annealed steel plate, the grains are randomly oriented. The silicon content of the alloy is 1.5% ~ 3.0%, or the sum of silicon and aluminum content is 1.8% ~ 4.0%. Products are usually cold-rolled plates or strips with nominal thicknesses of 0.35mm and 0.5 mm. It has the characteristics of high magnetic permeability, low coercive force and large resistance coefficient, so the hysteresis loss and eddy current loss are small. Mainly used as magnetic materials in motors, transformers, electrical appliances and electrical instruments.
