Seamless Rolled Ring Forging Process

Seamless Rolled Ring Forging Advantages

When acquiring metal rings for any application, issues can often be traced to the metal forming process. Cast rings are often plagued with poor strength and integrity. Rolled and welded or cut rings from plate are susceptible to fatigue, and carry excess material and processing costs. Custom forging performed by Ringmasters experts, however, allows greater versatility and improved quality while reducing material cost. Other benefits include:

• Controlled directional grain flow
• Increased strength
• Superior structural integrity
• Elimination of inclusions and porosity
• Minimized waste
• Eliminates welding, which reduces part fatigue and breakage risks

Compared to Hot Rolled Burnout Plates

The unidirectional grain flow inherent in hot rolled plate produces exposed grain ends when cutting the ring shape. This renders the material more liable to fatigue and more sensitive to stress corrosion cracking. The forging process shapes the material to the desired ring size so there is no need to remove excess corner stock or center holes. Additionally, material availability and plate size for large burnout plates may be difficult to obtain. Overall, forging allows greater size versatility while minimizing material waste, often reducing costs.

Compared to Castings

Cast rings typically do not have a desired grain structure. This greatly impacts the impact toughness, ductility and fatigue strength of the ring and can lead to a potential crack or fracture. Forging provides controlled directional grain flow or increased strength and offers superior structural integrity, eliminating inclusions and porosity commonly found in castings.

Compared to Rolled and Welded Rings

Fabricated rings are susceptible to porosity and inclusions in the material. Extensive welding on a rolled and welded ring reduces part integrity, jeopardizes corrosion resistance and may cause distortion of the ring's shape. With the absence of welding through the seamless rolled ring forging process, part integrity, corrosion resistance, and shape can be maintained&#;ultimately achieving a stronger ring while reducing risk of part fatigue and breakage.

When it comes to supplying your next job, it will take all sorts of parts and components that are made in different ways. One method of producing pieces are through rolled ring forging. There are a lot of benefits to the process that can really make a difference for your next project.

The Process

When it comes to the rolled ring forging process, it can be broken down into six steps. In the first step, the billet is cut to the proper size and is then upset to achieve the right properties. After that, the center is punched to create the ring that is rolled. After the donut is ready for ring rolling, the ring is placed on an idler roll and is manipulated by axial rolls and the drive roll. The ring diameter slowly increases as more pressure is applied and once the desired size is reached, the process is done.

Many Advantages

When it comes to this kind of forging, there are a lot of benefits. Given the forging process, one of the biggest benefits is how strong the final product is. The rings that are produced are stronger than other components and they maintain their strength in high-temperature environments. They are also cost effective compared to other methods of production. There is less machining involved, which cuts down on cost. In addition to how strong and cost-effective it is, you can also use a wide range of materials in production. You can forge allot, stainless steel, carbon, aerospace metals, and more.
