Numerical simulation for double-roller rolling process with deep-cylinder ring

Deep-cylinder rings, as the key mechanical parts of heavy energy equipment, have wide application in nuclear reaction pressure vessels, oil hydrogenation reactors and coal liquefaction devices. Double-roller rolling (DRR) is a new rotary plastic forming technology for deep-cylinder ring manufacturing, which has the advantageous of low energy and material consumption, high efficiency, good quality and large processing range, comparing to the conventional processing technology of free forging. In this paper, a numerical simulation investigation on DRR process of deep-cylinder ring is carried out based on ABAQUS FE software. A 3D coupled thermo-mechanical FE model is developed, the forming feasibility and basic deformation laws in the rolling process is analyzed. The results can provide a scientific guidance for the process design and optimization of the DRR with deep-cylinder ring.
