Notes:
Guide rolls play an important role in controlling both the ring circularity and the stability ofcold ring rolling process. However, it is difficult to predict and control the motion of the guide rollsdue to the complexity of process associated with the coupled effects of multi-factors. In this paper, areasonable controlling model of the guide rolls is proposed, and the functional relationship betweenthe motion track of the guide rolls and their setup parameters and process ones is established, bywhich the guide rolls motion track can be determined. On this basis, a 3D-FE simulation model forcold ring rolling is developed under the ABAQUS software environment and the effects of the initialposition and motion track of the guide rolls on the forming stability, ring circularity, rolling force, andoscillating are investigated. Taking the forming stability and ring circularity as objects, the optimuminitial position and motion track of the guide rolls are obtained
