An Investigation of Rolling Parameters for Rolling Process

摘要：

Rolling process involves geometric non-linearity,material non-linearity and boundary non-linearity,which is a complex and high non-linear problem.It is impossible to obtain analytical solution in terms of trying to roll or physical experiment because of high cost,waste time and venture.Finite element method is an effective one that can resolve large plastic deformation,thermo-mechanical coupling and complex boundary conditions between rollers and billet in the rolling process.FEM models of the rollers and billet are built by three-dimensional elastic-plastic FEM.The two-pass hot continuous rolling process of high-speed wire has been simulated accurately based on thermo-mechanical coupling condition.Equivalent of stress,equivalent of total strain and rolling force are computed for different initial rolling temperature 1000℃ and 1100℃.Furthermore,stress,strain,temperature and rolling force are also discussed for different gaps 8mm and 12mm between two rollers.The results of simulation supplied theoretical foundation for improvement of process plan,optimization of process parameters,change of microstructure,which were also useful for practical manufacture.
