1、 Definition and Characteristics

Titanium forging ring is a ring-shaped component made of titanium or titanium alloy as raw material and processed through forging technology. Its core features include:

1. High strength and lightweight: Titanium alloy has a high specific strength, and forged rings can significantly reduce structural weight while bearing high loads.

2. Corrosion resistance: The titanium surface oxide film endows it with excellent corrosion resistance to seawater, acidic media, chloride ions, etc.

3. High temperature resistance: Some titanium alloys can work stably for a long time below 400 ℃.

4. Process adaptability: Forging process can refine grain size, improve material density and mechanical properties, and is suitable for complex working conditions.

2、 Manufacturing process

1. Main process route:

Free forging: suitable for small batches or irregular forging rings, with high flexibility but low material utilization.

Ring rolling: Seamless ring parts are formed through radial rolling, with high efficiency and good dimensional accuracy, suitable for large-scale production.

Forging: Used for forging rings with high precision or complex structures, with high mold costs.

2. Key technical links:

Heating control: Titanium alloy forging requires strict temperature control below the β phase transition point to avoid grain coarsening.

Deformation rate: It is necessary to balance plastic deformation and crack risk, usually using multi fire forging.

Heat treatment: Solid solution and aging treatment can optimize the comprehensive mechanical properties.

3. Quality control indicators:

Chemical composition, microstructure, ultrasonic testing for internal defects, dimensional tolerances.

3、 Application Fields

1. Aerospace:

Utilize the high temperature resistance and lightweight characteristics of engine compressor rings, rocket fuel tank flanges, etc.

2. Chemical and Energy:

The flange and pipeline connection ring of the reaction vessel are resistant to strong acids, strong alkalis, and high-temperature and high-pressure media.

3. Ocean Engineering:

Deep sea equipment structural components, ship power system sealing rings, resistant to seawater corrosion and erosion.

4、 Selection and usage suggestions

Material selection:

Universal corrosion-resistant scenario: Industrial pure titanium.

High strength and heat-resistant scenarios: TC4 or TC11.

Process matching:

For high-precision requirements, ring rolling technology is preferred, and for complex structures, forging and machining are used.

Surface treatment:

Acid pickling and passivation enhance corrosion resistance, while sandblasting or polishing meet special surface roughness requirements.

Summary: Based on the above analysis, titanium forged rings, as high-performance structural components, have irreplaceability in the high-end manufacturing field, and their preparation technology continues to evolve towards high precision and low cost.
