• diameters300"

The production of seamless forged rings is often performed by a process called ring rolling on rolling mills. These mills vary in size to produce rings with outside diameters of just a few inches to over 300" and in weights from a single pound up to over 300, 000 pounds. The process starts with a circular preform of metal that has been previously upset and pierced (using the open die forging process) to form a hollow "donut". This donut is heated above the recrystallization temperature and placed over the idler or mandrel roll. This idler roll then moves under pressure toward a drive roll that continuously rotates to reduce the wall thickness, thereby increasing the diameters (I.D. and O.D.) of the resulting ring.

Our organization offering best open die forgings like hubs, gear blank pinions, king pins, turret disc etc.

We are dealing in joint less rings like seat rings for valves, ring gears, bearing rings, flanges, gasket rings, slew rings etc.
