Comprehensive analysis of titanium forging rings!
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.
