Silicon steel containing silicon content is 0.5 to 4.5% of very low carbon ferrosilicon alloy, due to the different structure and use is divided into non oriented silicon steel and grain oriented silicon steel. Silicon steel is mainly used for motors, generators, compressors, motors and transformers core, is the electric, home appliances and other industries indispensable raw materials products.
Silicon steel sheets cold rolling, hot-rolled two, the use of more cold-rolled silicon steel sheet. Cold-rolled silicon steel sheet along the rolling direction with excellent magnetic properties, not only in the strong magnetic field has high saturation magnetic flux density and low loss, but also have good magnetic properties (initial permeability) in the weak magnetic field. Because of the cold rolling process, the impurity content of the steel sheet is decreased, and the coarse grain is caused, and the magnetic permeability is increased and the hysteresis loss decreases.
The main requirements for the silicon steel properties are:
1, low iron loss, this is the most important quality index of silicon steel sheet. All core loss grades according to the lower grades, the iron loss, the higher.
2, a strong magnetic field of magnetic induction (magnetic), which makes the motor and transformer core volume and weight, saving silicon steel, copper and insulating materials, etc..
3, the surface is smooth, flat and thickness uniformity, can improve the core fill factor.
4, good film, for manufacturing micro, small motor is more important.
5, the adhesion and welding of the surface insulation film is good, can prevent and improve the film.
