Process Window and Repeatability of Thermomechanical Tangential Ring Rolling

International objectives towards improved resource and energy efficiency require new manufacturing processes, such as the proposed thermomechanical tangential profiled ring rolling process. A rapid cooling-down for microstructural adjustment a final calibration step via cold forming are combined into one single step. The reduction of process steps reduced number heating cycles present opportunities compared to traditional processes. Based on series experiments, this paper aims at showing potential in terms obtainable hardness microstructure. influence active cooling system feed is demonstrated. They identified essential with regard both geometry properties produced part. Finally, repeatability analyzed, disturbances ranked.
