Abstract：

Numerical simulation of forging process and air-cooling process before forging for a novel high alloy steel cold work roller was conducted by software Deform-3D. Firstly, according to the sizes of real product and head of hydraulic machine, the models of forging part and mold were established and meshed, and the thermodynamic measurement of the adopted high alloy steel was conducted and the material model was built. Then, through analyzing the distribution of temperature field and stress field for forging part during the air-cooling and forging process, the change law of temperature for forging part during the air-cooling process was obtained, and the temperature and stress characteristics at typical positions in the forging area during the forging process were given. In addition, the novel cold work roller was forged referring to the simulated results and combining with the actual experience, and the actual forging results were quite close to the simulated results. Thus, the feasibility of simulating the forging process by finite element method was verified to provide theoretical guidance for the actual forging production of cold work roller.
