Numerical Simulation of Multi-pass Rolling Force and Temperature Field of Plate Steel During Hot Rolling

Rolling force and temperature field are important parameters in the hot rolling process of plate steel.Most researchers use ANSYS/LS-DYNA and MSC.Marc to simulate the hot rolling process,however,software DEFORM-3D is not used widely in this field.Therefore,in this study,the commercially available finite element analysis software DEFORM-3D is used to simulate the distribution of rolling force,stress-effective,strain-effective and temperature field during the hot rolling process of plate steel with the size of 0.220 m×2.070 m×1.904 m.Both the simulated rolling force and temperature of the multi-pass are compared with the measured results.It is shown that the simulated values by the finite element method are approximate to the measured values in the hot rolling of plate steel.So the simulation can provide an important reference and optimization to make rolling process and parameters in steel factory.
