The biting stage of the strip rolling was simulated by using the three-dimensional large deformation thermo-mechanical coupled rigid-plastic finite element methods. The conditions in simulation were consistent with those in practical rolling processes. The simulated result was compared with the real process data, which shows that the method used herein to simulate the unsteady rolling state is practicable and reliable. Finally, the roll force distribution and the rolled piece deformation in the bite stage were studied and the rolled piece temperature influence on strip-head bending was analyzed.
