The Thermal-Mechanical Coupled FEM Analysis on 3-Roll Continual Tube Rolling PQF Deformation Process

Abstract:

Based on the characteristics of PQF deformation process, a thermal-mechanical coupled model of this process is established by the three-dimensional elasto-plastic finite element method. The simulation according to practical rolling process of a certain factory is completed. Some important parameters such as the finished size of the rolled product, the temperature variation curves of the key nodes on the tube, the rolling force and torque of each roller are predicted during this simulation. Comparison between simulation solutions and experiment results shows a good agreement, which means this model is capable of simulating PQF deformation process as well as forecasting product quality.
