摘要：

为了保证重大装备在重载、变载、冲击、高温、低温、腐蚀、辐射等严酷工作条件下长期稳定服役，对超大型环件的组织状态和力学性能的要求不断提升。通过锻压成形制造高性能无缝超大型环件，成为国家重大装备极端制造发展的重大需求。为此,总结了我国对于直径Φ5～Φ10 m超大型金属环件径-轴向轧制成形技术装备产学研合作的研究实践进展，建立了超大型金属环件径-轴向轧制物理模型，揭示了超大型金属环件径-轴向轧制成形规律，确定了超大型金属环件径-轴向轧制的力学、运动学、材料学条件，攻克了超大型环件轧制关键技术，并且研制了超大型环件径-轴向轧制系列装备。通过近20年的研究与生产，形成了超大型环件轧制理论，开发了超大型金属环件径-轴向轧制成形成套技术，将我国建设成为国际先进的超大型环件自主开发基地，有力促进了我国重大装备的创新发展。

In order to ensure a long-term stable service of major equipment in severe working conditions, such as heavy load, varying load, impact, high temperature, low temperature, corrosion, radiation, etc., the requirements of microstructure state and mechanical property of super-large ring were developed gradually. So a seamless super-large ring with high performance manufactured by forging and stamping technology became a great demand of extreme manufacturing development for national major equipment. Therefore, the research development of university-industry collaboration for radial-axial rolling technology and equipment of super-large metal ring with diameter of Ф5-Ф10 meters in our country was summarized, and its physical model was established. Then, its deformation law was revealed, and its conditions of mechanics, kinematics and material were confirmed. Furthermore, its key technology was overcome, and a series of equipment were developed. Over nearly twenty years study and production, the rolling theory of super-large ring was established, and the complete technology of radial-axial rolling for super-large metal ring was developed. Thus, the above works make our country to be an international advanced self-development base of super-large ring, which greatly promotes innovative development of major equipment in our country.
