Numerical Simulation Of 304 Stainless Steel Sheet Hot Rolling On Deform-3D

Based on the analysis of the development and present situation of the numerical simulation of the plate rolling process both home and abroad,the process of rolling is simulated by FEM method,so as to explore the law of the rolling process for the purpose of developing reasonable process parameters , optimizing the structure of the process and providing technical support and theoretical basis.The main contents of the subject as follows:(1) Based on the high temperature compression deformation test of 304 stainless steel,it can be obtained the stress-strain curves under the temperature of 950℃, 1000℃,1050℃, 1150℃and 1200℃. Using the experimental stress-strain data to simulating the process of the compression deformation test and established the numerical models under various temperatures.It showed the distribution of the stress and strain at various stages and the deformation process of the sample intuitively.Meanwhile,the result of the simulation were verified by the experiments.It was the foundation for the establishment of the hot rolling model of the 304 stainless steel under various temperatures,so as to the simulation of the hot rolling process is more accurate.(2) Simulating the 304 stainless steel hot rolling process and using the point tracking methods and cloud pictures to reflect the stress and strain at all stages directly in the whole process.The law of the that how rolling temperature,rolling speed and reduction to influence the rolling force has been obtained by analyzing many parameters which related with the rolling force.(3) The comparison of the simulated rolling results and the calculated results with Sims rolling pressure formula was studied, and the error of them was analyzed.
