Frame Casting Wind Turbine Main Frame Carrier QT400-18L Large sand castings
The primary parts that undergo casting include rotor hubs, axle pins, and main carriers. Main carrier are cast components in a wind turbine, and they are subjected to high stress. A wind turbine is a device that aids in converting the kinetic energy of wind into usable power. Casting refers to an industrial method of pouring liquid material into a mould which contains a hollow cavity of desired shape and then liquid metal is allowed to solidify. A wind turbine casting refers to components that are cast or molded to specifications all of which are then assembled to form wind energy systems. The components of wind turbines vary as per requirements, deployment area or location, type as well as required output size height and various other factors. The primary parts that undergo casting include axel pins, rotor hubs, and main carriers.
