Abstract. L-section rings are widely used in key basic parts, such as flanges and rotary supports. When the radial length of the ring step is large while the axial depth is shallow, traditional ring rolling with profile mandrel may result in forming defects such as incomplete filling of the steps. This paper proposes a near-net rolling technology for L-section rings with profile axial conical rolls. Firstly, a finite element model for the rolling process of L-section ring was established. Then the revolution laws of the ring geometric dimension and the metal flowing behavior during the rolling process with profile axial conical rolls were studied. Further, the influence of key process parameters on the forming effects was revealed, including radial-to-axial deformation ratio, rolling ratio, and roller motion. Finally, the feasibility of the proposed process method was verified by FE simulation and rolling experiments. The research results provide a technical guidance for the near-net rolling forming of L-section ring, contributing to the high-performance, efficient, and cost-effective manufacturing of parts like L-section flanges and rotary supports.
