Abstract:To non-oriented silicon steel,transverse thickness deviation is very important and key quality target. UCM tandem cold rolling mill is taken as the research object,an integrated simulation model of 6-High Mill and thin strip is established. By this model,considering the rolling stability and transverse thickness deviation control of non-oriented silicon steel,the EVC-Plus (Edge Variable Crown-Plus) roll with special double arc chamfering was designed and applied on a 1 720 UCM tandem cold mill. The actual application results showed that the EVC-Plus can be ground easily and the transverse thickness deviation of the non-oriented silicon steel was reduced from 12 to 8 μm or less by corresponding EVC-Plus contour for different product width,and the occurrence of strip breakage accident was greatly reduced.
