6. Special alloy rolls (such as nickel-based and cobalt-based alloys)
Core components: nickel/cobalt + chromium/molybdenum/tungsten and other elements
Performance characteristics: ultra-high temperature strength (resistant to more than 1000℃), thermal corrosion resistance
Main functions:
Aeroengine:
Manufacturing turbine blades and combustion chambers, withstanding extreme high temperatures and high pressures (such as Inconel 718 nickel-based alloy rolls).
Energy industry:
Used in nuclear power steam generators and petrochemical cracking furnace tubes to resist high-temperature oxidation and corrosion.
2. General advantages and industrial value of alloy rolls
Material performance optimization:
Through alloying design (such as adding alloying elements), it can be customized to meet single or composite performance requirements such as high strength, corrosion resistance, high temperature resistance, and conductivity, replacing the limitations of a single metal.
Processing convenience:
The roll form is convenient for continuous production (such as stamping, welding, stretching), and is suitable for large-scale industrial manufacturing (such as automotive sheet metal parts, container cylinders).
Cost-effectiveness:
Compared with castings or forgings, alloy rolls can achieve thin specifications and high precision through rolling processes, reduce material waste, and reduce processing costs.
Environmental adaptability:
Maintain stable performance in extreme environments (such as oceans, high temperatures, and strong corrosion) to extend the service life of equipment.
