Have you ever wondered how those doughnut-shaped rolled rings are formed? In the production of rolled ring forgings, manufacturers usually use metals or alloys that include aluminum or aluminum alloys, copper or copper alloys, titanium or titanium alloys, tool steel, carbon steel, stainless steel, alloy steel, cobalt alloy or nickel alloys.
What are Rolled Ring Forgings?
Rolled ring forgings also referred to as seamless forged rings are starting blank products that go through additional forming, machining and grinding in order to produce finished components. In most cases, its production involves a process called ring rolling on rolling mills that vary in size. Through this process, parts can be manufactured to tight tolerances and specific geometries that come with outstanding surface smoothness and concentricity. Forged ring products can have an outside diameter of a few inches like the smallest washer-ring to much larger parts that are over 9 feet in diameter.
How Rolled Ring Forgings are Produced
The first step involves the starting stock being cut to size by weight before it is upset in order to attain directional grain flow and the desired structural integrity. Next, the doughnut shape that’s needed for the ring rolling process is achieved by punching then piercing the workpiece. Once done, a completed preform will be ready for rolling. An idler roll is used to apply pressure to the preform.
