Production process and process of silicon steel sheet
Bell type furnace annealing is - oriented silicon steel, semi processed non oriented silicon steel with annealing temperature, but lower than the orientation.
Cold rolled grain oriented silicon steel process, a cold rolling, intermediate annealing, two cold rolling, annealing, removing carbon coated isolation layer, thermal annealing furnace is coated with an insulating layer, longitudinal smooth (or cross cutting and packing)Carbon removal annealing isolation coating coated MgO layer - typical isolation layer for oriented silicon steel.
Cold rolled non oriented silicon steel process of hot metal desulphurization pretreatment, converter steelmaking, continuous casting and hot rolling vacuum treatment, pickling, cold rolling mill, slitting machine / recoiler line, wide / narrow packing packing volume.In order to simplify the production process, the traditional non oriented electrical steel to reduce consumption, improve the magnetic properties of non oriented electrical steel, the BOF (BOF) -RH vacuum refining furnace - -LF thin slab continuous casting and rolling (CSP) - rolling - continuous annealing pickling process, to achieve more mass production.
