Different from the conventional ring rolling mill, the combined ring rolling mill has not only one main roll and one mandrel to enlarge the ring blank, but also two assistant rolls to deform the ring blank with the main roll continuous feeding. The novel ring rolling process can have three working modes: 1) conventional ring rolling; 2) cross rolling with three rolls surrounding the ring blank; 3) conventional ring rolling with cross rolling. Moreover, the new ring rolling process allows the transferring from one working mode to another. The process and the mill provide more flexibility for manufacturing different ring products. The stiffness condition at different working modes and the smoothly transferring conditions are first studied carefully. Then the combined ring rolling model for deep groove ring is established and evaluated.
