During the plate rolling process, due to the influence of the asymmetry conditions, the head of the rolled piece often shows bending. When the head of the rolled piece is bent to a certain extent, the damage to the on-site production equipment is extremely great. It is important to study how to control the head bending phenomenon in the production process to the actual production process. This paper chooses the range of parameters in which the plate is prone to head bending, and establishes the thermo-mechanical coupling model of finite element. Based on the inlet thickness, reduction ratio and roller speed difference as the initial conditions, the head bending was simulated to analyse the law affecting the plate head bending. At the same time, artificial neural network is used to train the simulation result data, and the nonlinear mapping relationship between each influencing factor and the head bending value is obtained, and then the control method of the plate head bending is established. The research in this paper has practical guiding significance for the development of plate technology.
