Abstract：

For the radial forging process of axle, the metal flow laws and strain distribution characteristics of axle head and axle body for cylindrical steel billet during the radial forging process were illustrated, and the forging penetration state of each contact point during hammer forging was calculated by using the forging penetration condition of circular cross-section axle by horizontal flat anvil. Then, on this basis, the minimum rotation angle for the radial forging of steel billet was calculated to be 13.3°, and the selection of pass reduction ensured not only greater than the minimum reduction required by the forging penetration conditions, but also met the pass reduction required by the microstructure and performance of forgings. Furthermore, based on the pass reduction required to complete the dynamic recrystallization of the pass or the static recrystallization between passes, the number of passes and the pass reduction distribution for forging the Φ256 mm steel billet into a non-powered axle with the axle body size of Φ219 mm and the axle neck size of Φ150 mm were reasonably designed, and the refinement and uniform recrystallization grain structure was obtained, achieving the refinement and homogenization of the axle grains.
