Distortion in Forged Rolled Rings

The thermal and rolling treatment of forged rolled rings sometimes leads to the creation of residual stresses, causing dimensional distortion in the results. However, there are tons of corrective measures employed by forging industries to address this concern. Ongoing studies are seeking to base newly-found corrective measures on the laws of physics.

How does Dimensional Distortion Happen?

Ring Rolling Process

First, the rings and other metal components are rounded and cut to how much it weighs. It is then processed to reach the intended integrity, directional grain, and other specifications. It is then punched and pierced to create a ring.

After that, it is placed on the ring mill to be rolled. The idler roll applies pressure against the drive roll and slowly the ring diameters are increased. Continued pressure is applied, and this reduces the wall thickness.

The axial rolls control the height as it is being rolled and this is repeated until the proper size and specifications are reached.

Distortion is Not the Only Problem

Once the metal components have been rolled at a certain forging temperature, most of them are heat treated. Due to this method, some parts of the components become ovular and distorted.

This occurs more often in huge metals with outer-diameter to wall-thickness proportions. More so, distortion is the only concern resulting from this method. Despite furnishing results that meet dimensional tolerances, residual stresses may still happen even after the product has been shipped to the customer.

The reason is that succeeding machining processes conducted by customers or other metal-production companies may cause extra distortion and deformation to the product.

Preventive Measures Must be Employed

In light of the intricacy of the issue, various ring-rolling companies approach it with only corrective measures while disregarding the essential preventive measures. There are companies which manufacture the metal components with great tolerances so it can be earlier manufactured to its final dimension and preventing any possible distortion.

Others employ corrective ring distortion measures through expansion and compression processing, partially relieving the components of residual stresses.

The Exceptional Process and Materials

Process Involved

The forging process starts with a circular metal component. Next, the component is cautiously pierced to create a hollow ring that looks like a doughnut. Then, the ring is moved and processed to recrystallization temperatures. Finally, after the recrystallization process, it is placed onto the idler roll and under pressure, directed towards the drive roll to produce the desired product.

Types of Rolled Rings

There are three main types of rolled rings:

  • Carbon – commonly used for pressure and structural vessel applications
  • Alloy – used for gear and bearing applications in addition to a variety of industrial equipment applications
  • Stainless Steel – mostly used for food and chemical processing applications.

Materials or Components Used

Seamless rolled rings can be made from any forgeable material! Furthermore, these include, but are not limited to:

The ability to create seamless rolled rings out of a wide range of materials is one of the many reasons why so many companies choose to work with them.

Advantages of Using Seamless Rolled Rings

Seamless rolled rings are used by various industries for many reasons. Moreso, some of the common reasons are a broader range of materials, better performance under heat, reduced costs, and greater strength. These rings can be created from numerous forgeable materials, including aerospace metals, carbon, stainless steel, and alloy.

Additionally, unlike the other ring components, it is easier to predict how these rings will react. These rings can maintain their strength despite the fluctuating temperature. To know more about seamless rolled rings, contact Ferralloy Inc. today!
