研究了环件轧制的直线进给运动、旋转轧制运动和环件直径增长运动规律，导出了相应的极限运动速度计算公式以及轧制环件极限尺寸和轧制时间，为环件轧制技术设计和过程控制提供了依据。
The law of linear feed motion, rotation rolling motion and ring diameter growth of ring rolling was studied. The corresponding calculation formula of ultimate velocity and the limit size and rolling time of the ring were deduced. Technical design and process control provide the basis.
