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.

Development and Characterization of Ring Rolling

Have you ever wondered how the ball and roller bearing races, pressure valves, pipes, and turbines are made? These metal pieces are produced through a process known as ring rolling. This is a specific category of metal rolling wherein a smaller diameter ring is rolled into a reduced cross-section and an accurate ring of larger diameter. Below are the facts about what ring rolling is, as well as its developments and characterization.

Facts to Know About

What is it?

Ring rolling is accomplished by using two rollers, one idle and one driven. The rollers move on either side of the ring’s cross-segment to create an efficient and precise motion. To guarantee the ring will maintain an unbroken width pattern the entire forming process, manufacturers use an edging roller during the industrial metal rolling process.

What are the Characteristics?

The process will retain the same volume of the metalwork. In this way, the geometric reduction in thickness will be reimbursed entirely because of the upturn in the ring’s diameter. Among the many characteristics, the most notable one is the manufacturing of seamless rolled rings. This procedure is used to produce not only flat rings but also rings that are designed to have different shapes and cross-sections.

Another significant characteristic of this process is that it can produce accurate parts and components with little waste of material. Additionally, the process involves an enhanced grain orientation that provides the metal robust strength appropriate for several applications.

What are the Developments?

This technique is gearing towards the new metalwork process with heightened geometries and more complex cross-section geometries. The applied knowledge gathered through the years by experts is insufficient to estimate the precise interface of various process parameters. Nonetheless, experts and manufacturers can still rely on simulation software to produce an accurate ring rolling model and evaluate the material properties and material flow with accuracy.

Rolled Ring Forgings | 3 Different Types

Rolled ring forgings are metal parts that are created through a process referred to as ring rolling. Rolled ring forgings are a very popular metal part. They are used for bearings, clutches, couplings, drives, flanges, gears, glass-lined reactors, machines, robotics, valves, and more. However, it’s important to note that all rolled ring forgings are not the same. Different types of rolled rings are used for different applications based on their unique properties and benefits. What are the different types of rolled ring forgings? Keep reading to learn about 3 of the most common types of rolled rings!

3 Types of Rolled Ring Forgings

what are the different types of rolled ring forgings

Stainless Rolled Rings

This type of rolled rings is made out of stainless steels. Stainless steels are steels that are heat and corrosion resistant and contain a minimum of 10% to 12% chromium along with other alloying elements. Stainless rolled rings are commonly used for food and chemical processing applications.

Alloy Rolled Rings

Alloy rolled rings are made out of alloy steel. Alloy steel is steel that contains additional alloying elements other than carbon in order to enhance its physical and mechanical properties. Typically, this type of rolled rings has enhanced strength and fatigue resistance. They are commonly used for gear and bearing applications in addition to a variety of industrial equipment applications.

Carbon Rolled Rings

This type of rolled rings is made out of carbon steel. Carbon steel is steel that contains up to around 1.2% carbon and all other elements are present in quantities too small to impact its properties. Carbon rolled rings are commonly used for pressure and structural vessel applications.

No matter which type of rolled rings is right for your project, you can count on us to provide it for you. Here at Ferralloy, Inc., we are known for our high quality rolled ring forgings and our ability to deliver them on time and at a competitive price. Contact us online today to learn more!
