Ring Rolling Process

1. Cutting

Starting stock cut to size by weight is first rounded, then upset to achieve structural integrity and directional grain flow.

2. Upsetting

Workpiece is punched, then pierced to achieve starting “donut” shape needed for ring rolling process.

3. Forming

Completed preform ready for placement on ring mill for rolling.

4. Peircing

Ring rolling process begins with the idler roll applying pressure to the preform against the drive roll.

5. Ring Rolling

Ring diameters are increased as the continuous pressure reduces the wall thickness. The axial rolls control the height of the ring as it is being rolled.

6. Sizing

The process continues until the desired size is attained.
