What is the difference between unoriented silicon steel and oriented silicon steel?
 

The grain of oriented silicon steel is basically in one direction, and the silicon content is high, which is mainly used in transformer manufacturing. Non-oriented silicon steel has disorganized grain distribution and low silicon content, which is mainly used in motor manufacturing. The silicon content is generally limited to 3%; Cold-rolled silicon steel is divided into cold-rolled non-oriented silicon steel and cold-rolled oriented silicon steel.

(1) The production process requirements of cold-rolled non-oriented silicon steel are relatively low, and the silicon mass fraction is between 0.5% and 3.0%. The finished product thickness after cold rolling is generally 0.35 and 0.5mm thick steel strip. Its Bs is higher than oriented silicon steel, uniform thickness, high dimensional accuracy, smooth surface, improve the filling coefficient and magnetic properties of the material.

(2) The silicon mass fraction of cold-rolled oriented silicon steel is above 3.0%, and the carbon mass fraction is 0.03%-0.05%. The content of oxide inclusion in steel is low and inhibitors are needed. Compared with cold-rolled non-oriented silicon steel, oriented silicon steel has lower loss, strong directional magnetic properties, and superior high permeability and low loss characteristics in its rolling direction. Cold-rolled oriented silicon steel, also known as cold-rolled transformer silicon steel, is mainly used in transformer manufacturing.

(3) Cold-rolled oriented silicon steel can also be divided into ordinary oriented silicon steel (CGO) and high magnetic induction oriented silicon steel (Hi-B) two categories. High magnetic induction cold-rolled oriented silicon steel is a single orientation steel strip, the main use is used in the manufacture of various types of choke coil, transformer and other electromagnetic components in electronic instruments
