Abstract: Based on the ABAQUS/Explicit platform, the thermo-mechanical coupling simulationof hot ring rolling process of a 6061 aluminum alloy ring casting blank was carried out, and the change law of the strain field, temperature field and force-energy parameters of annular billet during hot ring rolling was analyzed. The effects of mandral’s feeding speed,initial rolling temperature and friction factor on the forming process of the ring parts were mainly discussed. The results show that when the feed rate increases, the temperature, rolling force and rolling torque of the ring parts increase, the strain of inner and outer layers decreases, and the middle layer increases; When the initial rolling temperature increases, the ring temperature increases and the strain, rolling force and rolling torque decrease; When the friction factor increases, the strain decreases slightly, the influence on temperature is small, and the rolling force and torque increase. The grain size of the inner and outer layers of the ring is smaller than that of the middle layer, and the outer layer grain size is slightly smaller than that of the inner layer; the tensile strength, yield strength and elongation of the ring parts reaches 320 MPa,285 MPa and 15%, respectively.
