Product Description
We can produce and supply various specifications silicon steel coil, galvanized steel coil, carbon steel coil, galvalume steel coil, etc.
Silicon steel coil refers to a silicon alloy steel coil with a silicon content of 1.0-4.5% and a carbon content of less than 0.08%, also known as electrical steel. Silicon steel coil has the characteristics of high magnetic permeability, low coercive force, and large resistivity, so hysteresis loss and eddy current loss are small. It is mainly used as magnetic material in motors, transformers, electrical appliances and electrical instruments.
Silicon steel can be divided into two categories: oriented silicon steel and non-oriented silicon steel.
According to the manufacturing process and application, electrical steel can be divided into three categories: hot-rolled silicon steel, cold-rolled electrical steel and special-purpose silicon steel.
1. Hot-rolled silicon steel belongs to non-oriented silicon steel, which can be further subdivided into hot-rolled low-silicon steel (motor steel) and hot-rolled high-silicon steel (transformer steel). Among them, the silicon content of hot-rolled low-silicon steel is between 1.0% and 2.5%, and it is mainly used for household motors and micro-motors; the silicon content of hot-rolled high-silicon steel is between 3.0% and 4.5%, and it is mainly used for transformers.
2. Cold-rolled electrical steel can be divided into cold-rolled oriented electrical steel and cold-rolled non-oriented electrical steel. Cold-rolled oriented silicon steel is divided into ordinary oriented silicon steel and high magnetic induction oriented silicon steel, both of which are used in large, medium and small transformers; cold-rolled non-oriented electrical steel is divided into low-carbon electrical steel (silicon content less than or equal to 0.5%) and silicon steel (silicon content in 0.5%-3.5%). Low-carbon electrical steel is used in household motors, micro-motors, small transformers and ballasts, while silicon steel is used in large and medium-sized motors, generators and transformers. Judging from the above uses, cold-rolled oriented electrical steel is similar to hot-rolled high-silicon steel, both of which are used for transformers, while cold-rolled non-oriented electrical steel is similar to hot-rolled low-silicon steel, both of which are used for motors.
3. There are four types of special-purpose silicon steel: cold-rolled oriented silicon steel strip, cold-rolled non-oriented silicon steel strip, cold-rolled non-oriented silicon steel for magnetic switches, and cold-rolled high-silicon steel. The purpose of cold-rolled oriented silicon steel strip is pulse transformer, magnetic amplifier, high-frequency transformer and electric welding machine; the purpose of cold-rolled non-oriented silicon steel strip is high-frequency motor and generator; the purpose of cold-rolled non-oriented silicon steel for magnetic switch is Relays and magnetic switches; cold-rolled high-silicon steel is used for high-frequency motors, transformers and magnetic shielding.
