Ring rolling is a particular category of metal forming/rolling in which a ring of smaller diameter is rolled into a precise ring of larger diameter and a reduced cross section. The work will essentially retain the same volume; therefore the geometric reduction in thickness will be compensated for entirely by an increase in the ring’s diameter.
This is attained by the use of two rollers, one driven and the other idle, acting on either side of the ring’s cross section. Edging rollers are typically used during industrial metal rolling manufacture, to ensure that the part will maintain a constant width throughout the forming operation.
Rings manufactured by ring rolling are seamless. The resulting grain structure is circumferential, which gives better mechanical properties. This forming process can be used to manufacture not only flat rings, but rings of differently shaped cross sections as well, producing very precise parts with little waste of material.
