Cold-rolled non-oriented silicon steel sheet is made by hot-rolling steel billet or continuous casting billet into coils with a thickness of about . When manufacturing low-silicon products, the hot-rolled coils are pickled and then cold-rolled to a thickness of . When manufacturing high-silicon products, the hot-rolled strip should be pickled (or normalized at ~℃ and then pickled), cold rolled to a thickness of . The reduction rate is cold rolling to . or . thick. Cold rolling with this small reduction ratio can make the grains grow during annealing and reduce iron loss. Both cold-rolled plates are finally annealed in a continuous furnace at 100% hydrogen and nitrogen mixed atmosphere, and then coated with an insulating film of phosphate and chromate. Grain-oriented silicon steel generally contains %, which requires low oxide inclusion content in the steel, and must contain .~% and inhibitors (second phase dispersed particles or grain boundary segregation elements). The function of the inhibitor is to prevent the growth of primary recrystallized grains and promote the development of secondary recrystallization, thereby obtaining a high ()[] orientation. The inhibitor itself is harmful to magnetism, so after completing the inhibitory effect, it must be purified and annealed at high temperature. When using second phase inhibitors, the slab heating temperature must be increased to solid solution the original coarse second phase particles, and then precipitate as fine particles during hot rolling or normalization to enhance the inhibitory effect. The thickness of the cold-rolled finished product is..., or the process points are shown in the table. Cold-rolled oriented thin silicon steel strip is made by pickling, cold-rolling and annealing . or thick oriented silicon steel strip
