Abstract
A two-dimensional finite element mathematical model of rough rolling in "1+4" hot continuous rolling of 5052 aluminum alloy was developed by using finite element software Deform, The temperature and effective strain distribution of the strip in different process parameters has been investigated in by simulating the mathematical model in different simulation conditions. The process parameters such as rolling speed, initial temperature, contact heat transfer coefficient between work roll and strip have been considered. The simulation conditions were built by the means of orthogonal experiment. The process parameters, which can make the temperature and effective strain of the strip in a relatively uniformity distribution, were achieved by analyzing the simulation results under different simulation conditions. To judge the uniformity of the temperature and effective strain distribution of the strip quantitative in different simulation conditions, standard deviation has been used as a criterion.
