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.

Economic Advantages of Seamless Rolled Ring Forging

The process of seamless rolled ring forging involves the use of many different types of materials. These rings can be made of carbon, stainless steel, or alloy. Alloy steel contains an additional alloying material aside from carbon to improve the heat treat response or mechanical and physical properties of the rolled rings.

On the other hand, stainless steel material is used to create finished products that look elegant and can withstand rust and corrosion. Lastly, companies use carbon material to produce lightweight and heat resistant rolled rings.

How Cost-Effective is Seamless Rolled Ring Forging

Material Costs

Rolled ring forging can significantly reduce material costs! Typically, it uses fewer starting metal components to create the desired shapes. For instance, if the process requires a torch cut part, the complete center slug and entire corner stock are lost. With other forging processes, other parts are produced to a size that results in minimal waste.

Efficiency in Production

Using a rolled ring forging process, the same material can be created from several and various sizes of starting billets or ingots. It allows for a broader variety of inventoried material grades. The flexibility of the production process implies that forges materials of almost any grade can be designed and produced rapidly and more economically.

Reduced Reduction Rates

This type of forging eliminates or reduces rejections by yielding to enhanced structural integrity and using forging-quality materials. Additionally, the rolled ring forging process provides weld-free parts created with cleaner and quality material.

Machining Economies

Seamless rolled ring forging can likewise yield tool life advantages, lead time, and excellent machining. The reduced cost comes from forging a size that’s near its actual measurement instead of doing it with an alternative metal component like a bar or plate. With this type of process, it will require less machining to finish the product.

Get Seamless Rolled Ring Forging Products at Ferralloy Inc.

If you want to cut on production costs, seamless rolled ring forging is your best option. At Ferralloy Inc., we guarantee you that we only offer high-quality, engineered products.

Significance of Using Seamless Rolled Rings

Seamless rolled rings are shaped and bent through the process of ring rolling by using quality and efficient rolling mills. A circular preform of metal is perforated using the open die forging method to create a hollow shape that looks like a donut. Before placing the donut over the idler roll or the mandrel roll, the shaped metal is heated above the recrystallization temperature. With this, you’re guaranteed that finished products are only of the highest quality. Continue reading to know the significance of using seamless rolled rings.


Are Seamless Rolled Rings Worth the Investment?


Before anything else, it is best that you should know the various types of seamless rolled rings. Primarily, it is divided into 3 – stainless, alloy, and carbon rolled rings. Stainless rolled rings are quality steels that can withstand heat and corrosion. It contains a few alloy elements and about a minimum of 10% Chromium. Likewise, it is commonly used in chemical and food processing applications.

Alloy seamless rolled rings are also made of steel but contain a bigger quantity of alloy elements. Alloying elements provide steel with fatigue resistance and improved strength. Hence, the combination of these materials makes the finished product worth the investment.

As for carbon rolled rings, it contains steel and carbon. However, it is often combined with other elements that are small. Carbon seamless rolled rings are used for pressure vessel and structural applications.


Rolled and welded plates, as well as, casting methods are both metalworking processes that allow manufacturers to create rolled rings. Cast rings are known to be subject to inclusion defects that require additional machining, as well as, weld repair. Once the fabricated ring goes through a complicated welding process, the integrity of its part is reduced. Aside from its integrity, the shape becomes distorted and its corrosion resistance is also jeopardized.

On the other hand, with the seamless rolled rings process, the directional grain flow will result in an increase of the forging’s overall strength. More so, the maintenance of the part’s corrosion resistance and shape is guaranteed since there is an absence of welding.
