Ring rolled forging is utilized in the nuclear industry, machine shops, and pharmaceutical companies, among other places. Before beginning to forge a rolled ring, a metal disc is punctured to create a concave “doughnut” shape. This ring is warmed and then turned so the walls get thinner and the diameters get bigger.

The Process of Ring Rolled Forging

There are six basic procedures involved in creating a rolled ring. Billets are sized and twisted to achieve the desired characteristics in the first phase. When finished, a hole is punched in the centre of the rolled ring. When the donut is ready, the ring is put on an idler roll and moved by the axial and drive roll. As more pressure is placed on the ring, its diameter slowly grows. Once the size goal has been achieved, the process is complete.

There are many pros

There are many reasons to use these rings is:


Forgings are more potent than other parts and stay strong even when the temperature changes.

Cost Effective

The cost of making these rings is less than that of similar products. Because the rings are close to the shape of the finished part, less machining is needed.


Because ring rolled forging needs to be made at high temperatures, the grain pattern gives the metal more strength and resistance than other parts.

Better Under Heat

It is easier to predict how heated rolled rings will behave compared to other parts. When applying heat to most other parts, users must be careful to keep the piece from melting or changing shape. With forgings, users know exactly how hot it can get before it breaks.

More Things to Choose From

You can make these rings out of any material that can be forged, like alloy, stainless steel, carbon, or aerospace metals. Because they can be used in many different ways, they are a flexible and quick solution for manufacturers who need parts for markets like the chemical, power generation, and refinery industries.

Different ways that Seamless Rings can be Put Together

Ring for slew bearing can be made in many different shapes, from flat parts that look like washers to taller cylinders that can reach over 9 feet. Most of the time, the ratio of ring height to wall thickness is between 1:16 and 16:1. But if certain types of processing can be done, it is possible to change these ratios to be higher.

The Most Common Shapes of Rings

The most common and straightforward type of ring is the one with a cross-section in the shape of a rectangle. It should be noted, though, that shaped tooling methods can be used to make seamless rolled rings in a wide range of more complicated, custom shapes characterized by curved outer and inner diameters.


For your next job, you will need a lot of different parts and pieces that are made in different ways. Rolling rings and then forging them is one way to make things.
