Ring Rolling Machine for Forged Ring Production

A ring rolling machine is used to expand and form heated ring blanks into accurate seamless ring forgings. It reduces wall thickness, increases outside diameter and improves ring shape through controlled rolling between the main rolling wheel, mandrel and supporting components.

This machine is suitable for manufacturers producing forged rings for machinery, automotive, railway, shipbuilding, petrochemical, aerospace, energy and general engineering industries. It is commonly used for flanges, bearing outer rings, gear blanks, sleeves, wheel hubs and wind power components.

For buyers looking for a reliable ring rolling solution, we can support machine selection according to required outside diameter, roller width, productivity, motor power, ring material and production layout.

Roller width, rolling wheel size and slider stroke should match your ring profile and section requirements.

Production Capacity

Select the model based on required pieces per hour, shift output and future production growth.

Material Type

Carbon steel, alloy steel, stainless steel and non-ferrous alloys may require different forming conditions.

Workshop Layout

Machine dimensions, feeding direction, heating furnace position and handling equipment should be planned together.

Automation Requirement

Manual, hydraulic and CNC configurations can be selected depending on production volume and precision needs.

Benefits

Improved Production Efficiency

Ring rolling allows heated blanks to be formed quickly into finished or near-finished ring shapes, reducing overall processing time.

Reduced Machining Allowance

The process improves blank accuracy, helping reduce turning and cutting work after forging.

Better Forging Quality

Hot ring rolling supports improved metal flow and internal structure, which is important for demanding forged ring applications.

Lower Production Cost

Better material use, faster forming and reduced secondary machining can help reduce unit production cost.

Suitable for Batch Production

The machine is suitable for repeated production of standard ring parts such as flanges, bearing rings and gear blanks.

Supports Custom Projects

Machine configuration can be selected according to ring size, material grade, workshop layout and automation requirements.

Typical Applications

Flange Manufacturing

Used for producing pipe flanges, welding neck flanges, pressure vessel flanges and industrial connection rings.

Bearing Ring Production

Suitable for manufacturing bearing outer rings and other precision circular forgings used in mechanical systems.

Gear Blank Forming

Used to produce gear blanks before machining, helping improve material structure and reduce machining allowance.

Automotive Components

Applicable for hubs, sleeves, transmission parts and circular forged components used in vehicle manufacturing.

Energy and Wind Power Parts

Suitable for producing large ring components used in energy equipment, wind power and heavy machinery.

Petrochemical and Engineering Rings

Used for forged ring parts required in pipeline systems, pressure equipment and industrial machinery.

Process Flow

1. Billet Heating

The steel or alloy blank is heated to the required forging temperature before ring rolling begins.

2. Piercing or Preforming

The heated blank is pierced or preformed into a ring-shaped blank suitable for rolling.

3. Ring Positioning

The ring blank is placed between the rolling wheel, mandrel and guide rollers for controlled forming.

4. Diameter Expansion

The rolling wheel and mandrel reduce wall thickness while expanding the outside diameter of the ring.

5. Size Control

The ring is controlled during rolling to achieve the required diameter, width and dimensional tolerance.

6. Finished Ring Handling

After rolling, the forged ring is removed for cooling, heat treatment, inspection or machining.
