Rolled Rings

Ring Rolling

Ring rolling is a specialized metal forming process used to manufacture seamless rings of various sizes and shapes. It involves shaping a metal workpiece by subjecting it to controlled deformation between two rotating dies. The dies exert pressure on the workpiece, causing it to deform and take on the desired ring shape.

During the ring rolling process, the workpiece is typically heated to a specific temperature to improve its plasticity and reduce the forces required for deformation. This temperature is carefully controlled to ensure proper shaping and prevent material defects.

Ring rolling finds applications in various industries, including aerospace, automotive, energy, and industrial sectors. Typical products produced by ring rolling include seamless rolled rings, bearing races, flanges, gears, and other components that require strength, durability, and precision.

Overall, ring rolling is a versatile and efficient manufacturing process that allows for the production of high-quality seamless rings with excellent mechanical properties and complex geometries.

Types of Ring Rollings

1. Seamless Rolled Rings:

A ring rolling machine is used to shape a metal blank into a circle to produce seamless rolled rings. There are no connections or welds in these seamless rings. They are ideal for demanding applications in sectors including aerospace, oil and gas, and power generation because of their superior strength, structural integrity, and fatigue resistance.

2. Welded Rolled Rings:

To make a ring-shaped piece of metal, the ends of a metal strip or plate are welded together. They are frequently utilised in applications that call for greater diameters or thicker cross sections. Agriculture, machinery, and the transportation and transportation industries can all benefit from the economical solutions offered by welded rolled rings.

3. Contoured Rings:

Contoured rings feature an irregular cross-section or a non-circular shape. They are utilised in situations where the ring must fit a particular geometry or carry out a specific task. Forging or precision machining techniques can be used to create contoured rings, which can be customised to fit the specific needs of sectors including hydraulic systems, aircraft, and the automotive.

4. Flanged Rings:

On either one or both of the ring’s sides, flanged rings have an expanded rim or flange. The flange adds more surface area for connecting or attaching reasons. In sectors including automotive, construction, and heavy machinery where reliable mounting or fastening is crucial, flanged rings are frequently utilised.

5. Serrated Rings:

Serrated rings have several ridges or serrations running the length of its diameter. When the ring is utilised as a locking mechanism or for sealing applications, these grooves improve the grip or offer sealing capabilities. Serrated rings are frequently used in fields including oil and gas, fluid power, and industrial machinery.

6. Profiled Rings:

A profiled ring is one that has a cross-sectional profile that has been specifically created to satisfy the needs of a given application. To accommodate particular components or systems, these rings may have intricate curves, features, or shapes. Numerous industries, such as the automobile, aerospace, and industrial machines, use profiled rings

Ring rollings are metalworking processes used to produce seamless rings with specific dimensions and properties. The process involves shaping a circular metal blank into a ring shape using a combination of radial and axial forces.
Ring rollings can be performed with a wide range of materials, including carbon steels, alloy steels, stainless steels, titanium, nickel-based alloys, aluminum, and more. The material selection depends on the desired properties and application requirements of the ring.
Selecting the right ring rollings involves considering factors such as the desired material, dimensions, strength requirements, and application specifications. Working closely with experienced engineers or ring rolling manufacturers can help in selecting the most suitable options.
Yes, ring rollings can often be customized to meet specific requirements. Manufacturers can tailor the dimensions, materials, and properties of the rings according to the application needs.
Ring rolling is a forming process for the production of rings. Commonly a headed and pierced ring is used as raw part to be expanded and possibly profiled with a ring rolling machine. Two or more rotating dies (rollers) are used for this purpose. By reducing the wall thickness and the height of the ring, the diameter of the ring increases while maintaining a constant volume. Profiled rollers enable the production of near net shape ring cross sections.
