Abstract:The cold rolled high-strength container plate′s high requirement for its yield strength,forming property and dimensional accuracy has posed great challenges to the rolling stability and the shape control of cold rolling. The ribbed wave and the edge crack in the productive process of cold rolled high strength container plates were analyzed. The influence of the cooling process of the hot rolled strip area on the homogeneity of temperature and performance was studied through experiments. The strip′s deformation features in the process of UCM cold rolling was studied by FEM,the concurrent mechanism of wave shape and edge crack was developed,and the influence of different processes on the deformation homogeneity of the strip was analyzed. Combining theory and FEM,the optimization scheme for the performance homogeneity of the hot roller and the rolling stability of the coll rolling was presented. The shape quality of the cold rolled sheet is obviously improved and the edge crack defect of the strip is completely eliminated after the improvement. The rolling stability and product quality of cold rolled high strength container plates have been greatly improved.
