What is the difference between oriented electrical steel and non-oriented electrical steel?

1, both are cold-rolled silicon steel sheets, but the silicon content is different. The silicon content of cold-rolled non-oriented silicon steel sheet is 0.5%-3.0%, and the silicon content of cold-rolled oriented silicon steel sheet is more than 3.0%.
2, the production process and performance of different: non-oriented silicon steel sheet than oriented silicon steel sheet process requirements are relatively low.

Non-oriented silicon steel sheet is hot rolled billet or continuous casting billet into a thickness of about 2.3mm coil. For low-silicon products, hot rolled coils are cold rolled to 0.5mm thick after pickling. When making high silicon products, after hot rolling pickling (or after normalizing at 800 ~ 850℃ and then pickling), cold rolling to 0.55 or 0.37mm thick, annealing at 850℃ in a continuous furnace with hydrogen and nitrogen mixture atmosphere, and then cold rolling to 0.50 or 0.35mm thick by 6 ~ 10% low pressure rate. This small reduction rate of cold rolling can make the grain size grow and the iron loss decrease during annealing. Both cold-rolled sheets are finally annealed at 850℃ in a continuous furnace in a 20% hydrogen nitrogen mixture atmosphere, and then coated with phosphate and chromate insulating film. After cold rolling to the thickness of the finished product, the supply state is mostly 0.35mm and 0.5mm thick steel strip. The Bs of cold-rolled non-oriented silicon steel is higher than that of oriented silicon steel.
