The rolled ring forging process plays an important role in the manufacturing of certain components. Before we get into how you can buy rolled ring forgings, let’s talk a little more about what they are and what they are used for.
Rolled ring forging begins by taking a circle shaped metal that has already had the middle removed by open die forging to form a donut shape. The donut shape metal is then heated to a temperature beyond what is required for recrystallization before it is rolled. The roll is then made to move in the direction of the drive roll. This will rotate on a continuous basis so that the wall's thickness is reduced and the ring's diameters will be increased.
It’s possible to fabricate the rings in a variety of different configurations. The ratios of wall thickness to ring height tend to range from 1:16 to 16:1, however, it’s possible to adjust these proportions.
The most popular and simply shaped ring made is a rectangular-shaped cross-section model. It is possible though to make seamless rolled ring options in any number of more complicated, customized shapes by utilizing shaped tooling methods.
