英文摘要：
Cold ring rolling is a technology to produce high precision and performance seamless ring and its process has strong nonlinear. Real-time measurement and online control is one of the key technologies, which is the means to ensure process stabilization and improve ring quality. The process principle of cold ring rolling machine, including the system configuration of measurement and control principle is presented in this article. It describes in detail the characteristics about the computer control system, feeding servo system, measurement feedback system, process parameters and control criterion in cold ring rolling, compares the domestic cold ring rolling machine with the foreign one and points out that the research at present should emphasize on adaptive ability of the machine, servo system, rounding-roll control and process monitor.
