Abstract: Aiming at the large-volume, complex-structured and hard-to-form features of a ball mill liner forging, a die forging process was proposed. Through the Mn-Cr-Ni-Mo steel's isothermal compression test, the true stress-strain curve was obtained and the Arrhenius constitutive model calculated. The liner's forging process was simulated numerically using Deform-3D, and the effects of initial forging temperature, die forging speed, and friction coefficient on its forming quality and load were studied. The optimal process parameters were obtained: 1200 °C for initial forging temperature, 30 mm/s for die forging speed and 0.12 for friction coefficient. Under the optimal process parameters, the distribution of important fields, like the temperature field in the liner's forging process, was analyzed, and the liner plate's forming experiment was conducted. The sample's macroscopic and microscopic properties were analyzed by tensile and microscopic observations. The experimental results show that under the optimal process parameters, the forging quality is good, the tensile strength increases by 153.85% compared with the cast Mn13 liner, and the liner forging's microstructure is fine and uniform, meeting the product requirements.
