Advantages of Seamless Ring Rolling Forging Process

Ring rolling forging is a type of metal forging, where a smaller diameter ring is precisely rolled into a ring of large diameter. While there are many different types of cold, warm and hot forging.

Metals play an integral role in a number of industries, like construction, manufacturing, automotive and aircraft. Metal, in its highly ductile form, is required by these industries, to manufacture units such as transportation, vehicles, etc. This makes metal forging, a very important process for these industries.

Forging is a process through which molding or forming of metals is done. There are many different forging methods that are used for forging based on the requirement of the metal. One of the forging methods is seamless ring rolled forging.

What is Seamless Ring Rolling Forging?

In this type of forging, a hole is created on a thick plate of metal. This metal then goes through a squeezing and rolling process, which results in the formation of a ring. The size of the ring depends on the amount of metal that needs to be forged. This type of forging is very common in the aerospace industry.

The rings can be either cylindrical or flat in shape. Their height can range from 0.5 inches to 8 feet, and weight can be between 1 pound and 300,000 pounds. The shape, height and weight of the ring depend on the equipment that is being used for ring rolling forgings. The ratio of 1:16 at the bottom and top is common, but this can be changed as per the requirement.

Advantages of Ring Rolling Forgings

Reduce Oxidation: Ring rolling forgings prevent metal oxidation. As a result, the structures created from this process retain their shape as they do not react with oxygen.


Increased Strength: The rings created through this process have grains that improve the strength of these rings.

Increased Durability: General weight and proportional thickness of the separate section provides the ring with enhanced impact durability.

Wide Range of Applications: Ring rolling forging allows you to create rings in unlimited shapes and designs that can be used for a broad range of applications.

Customisation: Buyer will get precisely measured rings for the required application as the rings are created as per the specifications.

Affordability: It is less expensive than most other forging methods.

Easy to Perform: Ring rolled forging process does not require any major setup.

Quick Turn around Time: When compared with the making of closed die tool, ring rolling forging requires lesser lead time.

Ring rolled forgings is important for enhancing the tangential strength and ductility of metals, which makes it a preferable forging method used in the aviation industry for manufacturing gears, couplings, engines, sealed discs, cases, wheel bearing, flanges and a lot more.  View Source:
