Temperature Simulation of Single Pass Hot Rolling Process of Aluminum Alloy

In order to accurately predict the temperature field of rolled pieces,optimize the hot rolling process and improve the quality of the final product,the finite element temperature model of 3104 aluminum alloy plate during single pass hot rollig process was built up using MSC,Marc softwares by rolling test and two-dimensional elastoplastic finite element method.The effects of air cooling,contact heat transfer,plastic deformation heat and friction heat on the plate temperature were investigated.And the effects of rolling parameters including the initial temperature of plate rolling speed,contact heat transfer coefficient and reduction on temperature drop sensitivity coefficient were analyzed also.The results show that contact heat transfer had the most effect on the plate temperature and it was followed by plastic deformation,friction and air cooling.The initial temperature had the most effect on the temperature drop sensitivity coefficient and it was followed by rolling speed,contact heat transfer coefficient and reduction.
