Cold rolling process of silicon steel sheet

- Aug 31, 2018-

Cold-rolled silicon steel products high magnetic orientation silicon steel (codenamed Hib), oriented silicon steel and non-oriented silicon steel 3 categories. Hot-rolled silicon steel sheet rolled in the constant spraying pill pickling unit (CP) on the cutting tail, shot, pickling, trimming and oil painting, and so on, Hib silicon Steel and some high grade non-oriented silicon steel on this unit to the high temperature annealing, the purpose of the favorable inclusion of ALN solution and then the requirements of precipitation, in order to improve electromagnetic performance. The steel coils after pickling are cold-rolled on Sendzimir or four-roll mills, and Hib and low grade non-oriented silicon steels are rolled to the finished thickness, and other silicon steels are rolled to the intermediate thickness.
