Abstract：

From the measured data for aluminum experiments on Gleeble-1500,the constitutive equation was set up and the hot rolling model was established with the aid of elastic-plastic and thermal-mechanical coupled FEM.The reduction,work roll speed and contact heat transfer coefficient's influence on temperature difference across the thickness of slabs and flow stress curvature were analyzed.The rolling process at different reductions was simulated with the computer mode1,the calculated rolling loads were agreed well with the production logs and their errors were less than 15%.
