Forming process: Hot Ring Rolling for Producing Seamless Forged Rings

Ring rolling is a forming process for the production of rings. Commonly a headed and pierced ring is used as raw part to be expanded and possibly profiled with a ring rolling machine. Two or more rotating dies (rollers) are used for this purpose. By reducing the wall thickness and the height of the ring, the diameter of the ring increases while maintaining a constant volume. Profiled rollers enable the production of near net shape ring cross sections. The ring rolling processes enable the production of rings with diameters ranging from ten centimeters to ten meters. Though hot ring rolling is more common, cold rolling procedures have been deployed since the 1980s (e.g. for roller bearings or gear rings).
