Abstract：

In order to determine the deformation characteristics of V-shaped four-anvil radial forging for continuous casting round billet, the four-anvil radial forging process was simulated by finite element analysis software Simufact, and the deformation penetration problem and the distribution of axial stress and mean stress in the center of forgings were mainly analyzed. However, the surface metal deformation of forgings is large, and the deformation in the center is small, furthermore the minimum equivalent strain is in the center of a certain distance from the end. In the forging process, the axial stress in the center of deformation zone is tensile stress, and the maximum axial stress in the center changes slightly with the increasing of forging reduction. Under the given simulation condition, the maximum axial tensile stress in the center is 22 MPa, the mean stress in the deformation zone is negative, therefore, the stress state in the deformation zone is hydrostatic pressure. Furthermore, the hydrostatic pressure in the center of forgings is obviously smaller than that in the surface layer, and it increases with the increasing of forging reduction. Under the given simulation condition, the maximum hydrostatic pressure in the center of forgings is 49 MPa.
