Grain-oriented electrical steel is an indispensable soft magnetic material in the electric power industry. It is mainly used in various types of rectifiers, transformers, reactors, large motors, etc., and is used to manufacture the cores of various transformers.
Oriented silicon steel is an important soft magnetic material in the military and electronic industries. It is mainly used in high-frequency transformers, high-power magnetic amplifiers, pulse generators, general yoke coils, inductors, storage and memory components, switches and control components, Magnetic shielding and transformers operating under vibration and radiation conditions. Compared with other materials such as ferrite and amorphous materials, the iron core can be made very small due to the high saturation magnetic induction and high magnetic permeability of the 3% Si-Fe thin strip. Because it is a cold-rolled strip, it has a smooth surface, small differences between the same plates, good plate shape, and good processing performance. It can be made into iron cores of various shapes and specifications such as CD type, ring type, and rectangular type. It has a wide range of applications. Wide frequency range (50H-20KH). Silicon steel occupies an extremely important position in electrification construction. In a sense, the amount of silicon steel sheets used in a country can measure the degree of electrification in the country. Therefore, in the long run, electrical steel has great development prospects. At present, electrical steel is developing in the direction of replacing heat with cold, and cold-rolled silicon steel is developing in the direction of high grade and low iron loss, and low grade and high magnetic induction.
