Gleeble thermal simulation tests established the elastoplastic constitutive equation of GH3044. Using this constitutive relationship, the influence of three initial billet designs on ring rolling deformation and post-forging residual stress was simulated in the Forge finite element software. The results indicate that when there is a significant difference between the thickness and height dimensions of the ring, the primary rolling direction in the initial billet design should avoid aligning with either the excessively tall or excessively thick direction of the ring. After the ring rolling process is completed and cooled, the edges and corners of the ring’s end face experience compressive stress, while the core is subjected to tensile stress. This distribution aligns with the strain field distribution pattern of the ring.
