Wind power flanges are annular metal components used to connect core parts such as tower cylinders, nacelles, and hubs in wind turbine generators. They can transmit loads like wind pressure, gravity, and vibration, ensuring the structural stability and safe operation of the unit in complex environments. As the "key joints" of wind turbines, they are built around high-strength materials, precision manufacturing, and long-term corrosion resistance, featuring properties such as fatigue resistance, corrosion resistance, and high load-bearing capacity to guarantee the safe and efficient operation of the unit. Suitable for both onshore and offshore wind power, they are critical components that ensure the efficient operation and long service life of wind turbines.

Ring forgings are a product of the forging industry and a type of forging. They are ring-shaped objects formed by applying external force to metal billets (excluding plates), which undergo plastic deformation to achieve the required shape under appropriate compressive force. Such force is typically applied using hammers or pressure. The forging process creates a fine grain structure and enhances the physical properties of the metal. As common industrial products, ring forgings can be found everywhere in daily life.
