What is Seamless Rolled Ring Forging?

In this blog post, we’ll look at seamless rolled ring forging: what it is, what it’s used for, and the industries in which you’ll find it.

Seamless forged rings are created through a process called ring rolling, which uses a machine called a rolling mill. The rolling mill can generate rings of a range of diameters and weights.

The process starts with a circular metal piece that is pierced to form a doughnut-shaped component. After this ring is formed, it’s heated to recrystallization temperature. From there it’s placed on an idler roll and moves towards a drive roll. This step causes the ring to rotate and increases their diameter and the wall thickness of the rolling rings.

Seamless rings are produced using a range of configurations: tall cylinders, smaller parts resembling washers, etc., manufactured using a shaping tool.

 

Seamless rolled rings are used for:

Bearings

Clutches

Couplings

Drives

Flanges

Gears

Glass-lined reactors

Machines

Robotics

Valves

 

You’ll find them being used in the mining, power generation, and oil industry, as well as by the military. They help power rock crushing equipment, jet engines, windmills and railways.

Seamless Rolled Ring Forging Process Operations

1. The ring rolling process typically begins with upsetting of the starting stock on flat dies at its plastic deformation temperature - in the case of grade 1020 steel, approximately 2200 degrees Fahrenheit.

2. Piercing involves forcing a punch into the hot upset stock causing metal to be displaced radially, as shown by the illustration.
