自1842年世界第一台环型件轧机诞生以来,大型环形件轧制生产工艺流程,形成了四种主要类型.本文对这四种工艺流程进行了比较,并介绍了现代轧制工艺流程的特点,尤其着重介绍了大型环形件轧制工艺的新发展.轧制生产大型环形件是从生产火车轮箍开 Since the birth of the world’s first ring rolling mill in 1842, four major types of rolling processes have been formed: In this paper, the four processes were compared and the process of the modern rolling process Features, with particular emphasis on the introduction of large ring rolling process of new developments. Rolling production of large ring is from the production of the train wheel hoop open
