Electrical steel plate (also known as silicon steel sheet or silicon steel sheet) refers to a silicon iron soft magnetic alloy with extremely low carbon content (after annealing, the carbon content is below 0.005%), generally with a silicon content of 0.5% to 4.5%. Adding silicon to iron can improve its electrical resistivity and maximum permeability. Mainly used to manufacture iron cores for various transformers, motors, and generators. Electrical steel plates are divided into two categories, namely oriented electrical steel plates and non oriented electrical steel plates.

SMSTEELQ&A

Q: What is silicon steel? What is electric steel?

A: Electric steel is magnetically soft material among functional material, and is most wildly used. Generally speaking, silicon steel refers to electric steel with silicon content between 0.5%~6.5% Si. The general electric steel also includes the part that contains little silicon (Si<0.5%). However, nowadays the 2 concepts are not clearly defined, and can be interchangeable.

Q: Classification of electric steel

A: It is roughly classified into hot-rolled electric steel and cold-rolled electric steel. Zhongyuantong steel produces cold-rolled electric steel, which can be further classified into oriented electric steel and non- oriented electric steel.

Q: What is magnetic field?

A: The space field for the acting force between the two magnetic poles is described as magnetic field strength H, the unit is A/m (Ampere/meter). It is the driving primary field produced by external input electric current after the electric steel is made into motor.

Q: Difference between electric steel B50A300 and B50AR300

A: B50A300 is whole processed product. It can be put into use after being purchased or annealing (reducing the loss through stress relief and construction perfection). But B50AR300 must go through annealing before use.

Q: Difference between whole processed silicon steel and semi- processed silicon steel

A: The target of whole processed non-oriented silicon steel annealing is to achieve targeted magnetic property (guarantee value), with the consideration of mechanical property required by stamping and the surface coating. The target of semi-processed product annealing is to achieve the mechanical property required by stamping. The manufactured magnetic property is so poor that the user has to do annealing and bluing to the magnet core so as to achieve the required magnetic property and surface insulation. There can be coating on the semi-processed non-oriented electric steel (applied in Japan market) or no coating (applied in American market, CRML).

Q: Influence of electric steel hardness on product process property

A: The mechanical property of the material has direct influence on the processing property. Various electric steel materials are used in various industries according to their characters. Processing mold and mold adjustment are critical to processing property. Zhongyuantong steel maintains the stability of product mechanical property and guarantees the user’s processing property.
