Analyses are developed for predicting roll force and torque during ring rolling between plain cylindrical rolls. A nomograph is given to allow easy application of the theory. Conventional analyses for flat rolling are not generally appropriate to ring rolling, whereas the present theory considers the particular roll geometry and rolling conditions encountered in the process. Measurements of roll force and torque, taken during ring rolling experiments, are shown to be in good agreement with the theoretical predictions. The experiments are carried out on a new experimental mill having a mandrel which retracts axially for loading and unloading the ring, and is symmetrically supported between roller bearings within a four-column frame during rolling. This arrangement is believed to offer certain advantages over most commercial machines.
