Abstract：

In order to predict the wear law of die steel during hot extrusion process accurately, the study on hot extrusion wear of H13 die steel based on modified Archard wear theory model was conducted. According to the change of wear factor and hardness, the Archard wear theory model was modified, and considering the influence of extrusion times on die wear, the finite element model of hot extrusion was established by Deform. Then, the influence laws of wear factor, hardness and extrusion times on die wear were studied. Furthermore, the punch wear amount is small at the beginning of extrusion, and then it increases rapidly with the increasing of extrusion times. When the extrusion is up to a certain number of times,
the wear amount turns and then changes smoothly. Finally, the prediction model of hot extrusion wear for H13 die steel was established, and the reliability of the prediction model was verified by hot extrusion physical test. The research results provide a theoretical basis for predicting the die life during hot extrusion process for H13 hot-working die steel.
