Applications
Cutterhead Blades:
Cutterheads of shield tunneling machines are equipped with blades for cutting through underground rocks or soil. These blades are typically made of hard alloys due to their excellent hardness and wear resistance, enabling sustained operation in challenging underground conditions.
Shield TBM Disc Cutters:
Shield TBM disc cutters are crucial components that support and guide the cutterhead, ensuring the smooth advancement of the tunneling process. These disc cutters also require wear-resistant and corrosion-resistant properties, which alloys can provide.
Cutterhead Disc Cutter Seats:
Seats for holding the cutterhead blades in place also often utilize alloy materials to ensure blade stability and durability.
Drill Bits and Cutting Tools:
In certain shield tunneling applications, drill bits and other cutting tools are used. The manufacturing of these tools also frequently involves alloy materials to ensure sufficient cutting capabilities and lifespan.
Characteristics
Hardness:
Alloys exhibit exceptional hardness, maintaining stable cutting performance under high pressure and friction, thereby extending the lifespan of tools.
Wear Resistance:
Cutting through underground rocks and soil subjects tools to severe wear. Alloys' wear resistance enables blades and cutting tools to maintain effective cutting performance in harsh environments.
Corrosion Resistance:
Shield tunneling machines can encounter moisture, corrosive substances, and other factors underground. Alloys' corrosion resistance helps protect tools from damage.
Thermal Stability:
During tunneling, tools generate heat due to friction. Alloys typically possess good thermal stability, maintaining consistent performance even in high-temperature conditions.
Strength:
Alloys generally have high strength, which is crucial for withstanding cutting and impact forces.
In summary, alloys play a critical role in shield tunneling machine applications, offering characteristics such as wear resistance, corrosion resistance, and high hardness to ensure efficient operation in complex underground environments. Different types of alloys are used based on specific engineering requirements and material properties.
