Abstract According to the geometric pass and technological characteristics in PQF retained mandrel rolling process, a three-dimensional nonlinear finite element model was established for the whole rolling process. The size of pierced billet and the parameters of force and energy were predicted in this model. The simulation results were in good agreement with the experimental results in a certain factory. The formation mechanism of the tension in PQF continuous rolling process was analyzed, and influence rules of the tension on the metal rheological law, the neutral curve distribution, the steel pipe section size, the force and energy parameters were researched, which provides a theoretical guidance for optimizing the PQF rolling process parameters and controlling product quality.
