What Is Forged Rings?

Forged rings is a kind of metal component in round shape, normally manufactured through forging process, usually in round shape or oval-shape, obtain even thickness and good mechanical properties. The size of forged rings can range from few centimeter to several meters. Depending on certain application scenario.

Classification of Forged Rings

Based on Materials:

Carbon steel forged rings

Alloy steel forged rings

Stainless steel forged rings

Titanium alloy forge rings

Nickel-based alloy forged rings

Based on Shape and Structure:

Round forged rings

oval-shaped forged rings

Special shaped forged rings

Based on Application Scenario:

Energy-related forged rings

Forged rings for mechanical manufacturing

Forged rings for shipbuilding

Forged rings for oil and chemical industry

Manufacturing process of forged rings

Raw Materials Preparing

Choose suitable raw steel materials, such as carbon steel, alloy steel, titanium alloy steel, nickle-based alloy steel, choose chemical component and properties of the materials according to application requirements.

Heating:

Heat the billet to forging temperature range. The forging temperature is usually above the recrystallization temperature, to ensure the materials have good plasticity.

Forging:

Place the heated billets to the forging equipment, such as Ring rolling machine.

By applying pressure to billets through roller and shafts of the forging equipment, transform it into a ring structure.

During forgings process, the outer diameter of the billet is increasing while the inner diameter is decreasing, finally the required circular dimension will achieved.

Heat treatment:

After forging, forged rings usually need to be heat treated to improve its mechanical properties and organizational structure.

Heat treatment process include annealing, normalizing, quenched and tempered. Certain processing method depending on the materials type and final usage requirement.

Machine processing:

Machine the forged rings according to the design specifications, such as turning, milling, drilling, etc. To achieve accurate size and surface roughness.

Machine processing could remove the excess materials generate during forging, to ensure the size precision of the materials.

Inspection:

Inspection of the forged rings, include dimension test, UT test and mechanical property inspection.

Ensure the forged rings meet the design requirement and quality standard.

Characteristic of the Forged Rings

High strength and high toughness: Forged rings are manufactured through forging process, metal fibers are distributed in a circular direction, obtain high strength and high toughness, could withstand large loads.

Uniform organizational structure: During the forging process, metal grains are refined and the structure become uniform, which enhances the material’s mechanical properties and fatigue resistance. High dimensional accuracy and surface quality.

Excellent corrosion resistance: Depending on the material selection, forged rings can have excellent corrosion resistance, making them suitable for harsh working environment.

Application Scenario of Forged Rings

Aerospace: Used to manufacture key component in aircraft engines, such as fan disc, compressor disc, and turbine discs.

Energy: Used in equipment such as reactor pressure vessels and steam generators for nuclear power plants.

Machinery manufacturing: Used in components such as bearing housings and flanges in automobiles and construction machinery.

Shipbuilding: Used in components such as propellers, rudder shafts, and gearboxes for ships.

Petrochemical industry: Used in equipment such as high-pressure pipelines, valves, and pumps.

Rail transportation: Used in components such as wheel hubs and gears for railway vehicles.

Advantage:

Excellent properties: Forged rings obtain high strength, high toughness and good fatigue resistance, could meet high load and complex work environment requirements.

High reliability: The forging process ensures uniform structure and dimensional stability of the ring forgings, improving product reliability.

Customized production: We can produce different size, shape and properties forged rings according to customer’s needs.

Conclusion

Forged rings is a kind of metal component manufactured through forging process, wildly used in aerospace, energy, machinery, shipbuilding, petroleum and other industries. Based on materials, forged rings could be divided into carbon steel, alloy steel, stainless steel, titanium steel and nickle-based alloy steel; Based on shape and structure, can be divided into round, oval, and special-shaped types; by size into small, medium, and large; by use into aerospace, energy, machinery, marine, and petrochemical fields; and by process into open-die forging, die forging, and ring rolling. They have high strength, good toughness, corrosion resistance, and good size accuracy. These features make them suitable for different working conditions and important parts in modern industry.
