| Abstract: | In order to improve the internal quality of heavy plate,the effects of rolling with inter- pass cooling technology on deformation through slab thickness was studied by finite element analysis.Effects of cooling and rolling parameters on internal deformation degree of plate were discussed.The metal flow and deformation law of workpiece by rolling with inter- pass cooling technology were obtained,under the conditions of different temperature between plate core and surface,different slab initial temperature and slab thickness.It provided a reference for the process design in the industrial application. |
