What are seamless rolled rings used for?

Seamless rolled rings are employed in multi-million to multi-billion dollar industries such as mining, power generation, oil and gas industry, aviation and aerospace, defence sector, etc. Hence, it is very essential that we understand the process that gives rise to these mechanical components.

What are the advantages of seamless rolled rings?

In Engineering, advantages (or disadvantages) must be taken into account before initiating a complex mechanical process. Clearly, the uses of seamless rolled rings as listed above indicate that there is plenty of need for more of them. Below are some of the advantages that this forging process brings.

1. Strengthens the metal at high temperatures thereby offering durability when used in other industrial applications.
2. Highly cost effective.
3. The entire forging process defines the character of the metal used. Thereafter, a determination is made if the use of this metal is worth it or not.
4. Fewer restrictions.

Seamless Rolled Rings Forging Process

To summarize, the whole process takes place on rolling mills that are calibrated to generate rings of various sizes. Typically, the outer diameter spans from a couple of inches up to 300 inches. Weight-wise, these rolled rings could weigh anywhere from 1 lb to over 300,000lbs, depending upon the requirements.

Now that you have a basic understanding of the said process, it’s time to get down to the specifics.

Rolled ring forging process in detail:

In the primary stages of this process, the raw material is also known as ‘ingot,’ ‘billet,’ or simply ‘stock,’ is set between a flat dies after being heated to high temperatures where it behaves almost like a plastic, thus making it easier to give it any preferred shape.

Thereafter, the centre is punched through-and-through to create a ring rolling ‘donut.’ Since the ‘ingot’ is maintained at hot temperatures, the displacement of the metal in the middle takes place radially.

Moving ahead, ID and OD pressures are applied to the ring consecutively increasing the ring diameter. This goes on until the desired ring diameter is achieved after which, the seamless rolled rings forging process comes to an end.

Multiple shapes & sizes:

What gives seamless rolled rings a definite shape is a ‘shaping tool.’Using this tool, the forged rings can be given any shape or size, from cylindrical to washer-like parts.

What materials are used in this process?

Basically, it depends on the unique requirements of each client.While stainless steel or an alloy of iron ore are highly preferred, titanium, aluminium and other metals or alloys are not too far behind.

Regardless the metal or alloy used, the remaining process stays the same. But of course, special considerations are made for shaping, sizing, heating or cooling the metals since each has a distinct heating and cooling temperatures.
