Seamless Rolled Rings Forgings

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. Seamless rolled rings offer a controlled grain flow, which gives added strength and fatigue resistance not found in welded rings or torch cut rings.

Seamless rings can be produced in configurations ranging from flat, washer-like parts to tall, cylindrical shapes, with heights ranging from less than an inch to more than 9 feet. Wall thickness to height ratios of rings typically range from 1:16 up to 16:1, although greater proportions can be achieved with special processing. The simplest, and most commonly used shape is a rectangular cross-section ring, but shaped tooling can be used to produce seamless rolled rings in complex, custom shapes with contours on the inside and/or outside diameters.KEYWORDS for this process: forge, forger, forgers, forged
