Forging / Ring Rolling
The Ring Rolling Process
Ring rolling produces seamless rolled rings with circumferential grain flow — the strongest possible structure for bearings, gears and flanges. Monmet supplies rolled rings in a wide range of tonnages and large outside diameters in carbon, alloy and stainless steels.
Process
A pierced doughnut preform is rotated between an idler and a driven roll while a side mandrel reduces wall thickness and grows diameter. The result is a one-piece ring with no weld seam and a continuous circumferential fiber pattern.
Typical Applications
Slewing bearings for cranes and wind turbines, gear rings, large flanges (ANSI 600#–2500#), pressure vessel courses, tube sheets and bull gears.
Profiles
Rectangular, contoured (T, L, U) and custom step profiles supplied in the as-rolled state or heat treated and rough machined.
