Abstract: High Performance Ring Parts(HPRPs) are a widely applied in many industry sectors, whose manufacturing technology is an important symbol of the national mechanical manufacturing capacity. Ring rolling is a continuously partial plastic forming technology, which is an advanced forming manufacturing technology of HPRPs. On basis of the research foundation of authors in rolling of HPRPs, the theory, applications and new technologies of HPRPs rolling are systematically introduced. The forming characteristics of bearing rolling are analyzed; the ring rolling forming theory are formulated, which include the rolling condition and force and energy computational method; the applications of HPRPs rolling technology in China mechanic, aviation and aerospace industry sectors are introduced; the new development of ring rolling process and equipment are described. Combined with the progress of national key R & D plan, the construction status of intelligent rolling and green rolling of HPRPs is introduced. China has become an important country of HPRPs rolling. As an efficient manufacturing method of fundamental, key and important parts, green and intelligent rolling for HPRPs would provide the best solution for China’s double carbon target.

Key words: ring parts, ring rolling, green manufacturing, intelligent manufacturing
