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.

Complex Facts About Ring Rolling

When it comes to forging, it is ideal that you get advice from specialists. We know this matter involves intricate and elaborate details. At Ferralloy Inc., we make sure that you are provided with detailed information about the engineered products we offer.

Seamless Rings: Are Seamless Rings Right for You?

The process of forging seamless rings plays a significant role in the manufacturing of other important components. Forging is a technique of manufacturing strong, typically metal, components for use in machinery. The foraged items can be made for when apparatuses are required for the expansion of wind turbines or high-quality gears for mechanics. Seamless ring forging is used to manufacture durable, high-quality products.

The What And How of Seamless Rings

Materials Used

A distinguishable aspect of seamless rings is dependent on the material used. With every tool and metal component in the manufacturing industry, it’s vital they are created to be almost indestructible. This includes literal hardness, strength, and the ability to resist wear and tear as they age.

Among the three elements, the most important is the ability to withstand wear and tear. Because most of these products will be used in engines and machines, they will get beat up pretty well. These tools and components must also sustain heat as these are exposed to high temperatures.

Types of Steel

How are seamless metal rings made?

The types of steel used for seamless rings are:

  • Stainless steel
  • Alloy steel
  • Carbon steel

Stainless steels contain a higher amount of chromium than other types of steel. As a result, seamless rolled ring forgings made of this type of steel are corrosion resistant and therefore, should not rust.

Alloy steels have great strength, hardness, wear resistance, and enhanced toughness. However, additional heat treatment may be required in order to achieve these attractive properties.

Lastly, carbon steels possess properties that are similar to iron. Within carbon steels, there are additional classifications: low carbon steel, medium carbon steel, and high carbon steel. The lower the carbon content, the cheaper and easier it is to shape. 

Process

How are seamless rings made?

The seamless ring process begins by taking a circle-shaped metal that has already been pierced to look like a doughnut, thus the ring name. The shape is then heated beyond the required temperature for recrystallization. Finally, it is shaped into the desired shape.

Seamless Rings | Frequently Asked Questions

Seamless rolled rings are one of the most widespread components in metalworking today. These cylindrical metal parts, which are relatively short in height and possess a hollow middle section, are so popular that it’s hard not to run into these components on a daily basis. A wide range of industries utilize rolled rings, from the nuclear industry to pharmaceutical companies and everything in between. However, despite being so prevalent, chances are that you still have a plethora of questions regarding this type of metal component. But don’t worry, we are here to help! Keep reading to finally get the answers to some of the most frequently asked questions about seamless rings.

How Are Seamless Rings Made?

Seamless rolled rings are produced through a process called rolled ring forging. Rolled ring forging consists of taking a circular metal preform and piercing it to form a doughnut shape. The ring is then heated and rotated to reduce its wall thickness and increase its diameter until the desired shape and size is achieved.

What Materials Are Used for Seamless Rings?

Seamless rolled rings can be made from any forgeable material. These materials include alloy steels, stainless steel, carbon, Haynes, Inconel, superalloys, aluminum, and more. The ability to create seamless rolled rings out of a wide range of materials is one of the many reasons why it is such an appealing metal part.
