What is the difference between hydroelectric and thermal forging?

Hydropower forgings and thermal forgings are both key components used in power generation equipment, but they have some differences in terms of production processes, materials and performance requirements.

Production process: hydropower forgings usually use hydraulic turbines, generators and other components in hydroelectric power generation equipment as raw materials, and are produced through forging, heat treatment, machining and other links. The thermal power forgings are based on the rotor, protection ring, impeller and other components in the thermal power generation equipment as raw materials, and are also produced through forging, heat treatment, machining and other links.

Materials: The materials of hydropower forgings are usually corrosion-resistant and high-strength materials such as stainless steel and nickel-based alloys, because the water flow in hydropower equipment will have a scouring and corrosion effect on the components. The thermal power forgings usually use high-quality carbon structural steel, alloy structural steel and other materials, because the thermal power generation equipment in the high temperature, high pressure, strong oxidation and other environments will have different effects on the components.

Performance requirements: hydropower forgings need to withstand the water pressure, water erosion and other effects in hydropower equipment, while ensuring high precision, high stability and long life. Therefore, hydropower forgings need to have excellent corrosion resistance, wear resistance and fatigue resistance. The thermal power forgings need to withstand high temperature, high pressure, strong oxidation and other effects, while ensuring high strength, high hardness and good fatigue resistance.

Application: Hydropower forgings are mainly used in the core components of hydraulic turbines, generators and other hydroelectric power stations, with environmental protection, high efficiency, sustainable and other advantages. Thermal forgings are mainly used in steam turbine, gas turbine and other core components of thermal power stations, with the advantages of high power and high efficiency.

In short, there are differences between hydropower forgings and thermal forgings in terms of production processes, materials and performance requirements, which is mainly due to their different application fields and working conditions.
