Abstract：

In order to improve the product quality, optimize the process flow and save the research and development time and cost of G115 martensitic heat-resistant steel, the extrusion process of large-diameter seamless tube of G115 steel was simulated by finite element software ABAQUS, and the difficulty of simulating super-large plastic deformation was solved by using the Arbitrary Lagrangian-Eulerian (ALE) formulation. Then, an accurate friction model and a material model considering various influencing factors were established, and the accuracy of the model was verified by comparing the simulation and experimental results. Furthermore, the influences of initial extrusion temperature, extrusion speed, friction factor and maximum shear stress on the extrusion were studied. The results show that with the increasing of initial extrusion temperature, the required extrusion force decreases, while the influence of the extrusion speed is opposite. The greater the extrusion speed, the greater the required extrusion force. The friction factor and the maximum shear stress are both positively correlated with the extrusion force.
