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.

Understanding Carbon Steel Rolled Rings

Creating carbon steel rolled rings is a process that uses carbon steel. It contains up to around 1.2% carbon while other present elements are in quantities too small to impact its properties. With this material, carbon rolled rings are commonly used for pressure and structural vessel applications. To understand more about carbon steel rolled rings, below are the facts you need to know.

All About Carbon Steel Rolled Rings

Why Choose Carbon Steel

Manufacturers engaged in rolled ring production will tell you that carbon steel is among the most cost-effective option when it comes to steel. Since it is cost-effective, the rolled rings process can attain the high strength a stainless steel can offer. However, you can still achieve good quality products that can be hardened through tampering and quenching.

Carbon Steel Grades

High-grade carbon steel rolled rings is often used in applications that don’t require high temperature or high strength environments. Below are the carbon steel grades you need to familiarize yourself with.

  • A Grade – This type of carbon steel is ideal for oil field applications since it is corrosion resistant. It comprises alloy substance such as nickel or manganese. Thus, it can enhance the toughness and hardenability of the metal produced.
  • High Carbon Steel – Akin to A Grade carbon steel, this type also comprises manganese to improve hardenability and toughness. It can be heat treated or welded for higher durability.
  • Low Carbon Steel – This is commonly known as re-sulfurized carbon steel as it contains sulfur to provide exceptional machinability.
  • Plain Carbon Steel – The least expensive type but provide a good welding factor. It comprises high carbon content and low alloy content. Hence, plain carbon steel can offer excellent surface hardness and good toughness.

Capabilities of Carbon Rolled Ring

Carbon rolled rings utilize a foolproof forging process that creates seamless rolled rings with outstanding circumferential grain flow and ample internal structure. Also, the precision rolling procedure offers exceptional surface smoothness and concentricity.

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.
