Wind Power Hub QT400-18AL EN-GJS-400-18-LT Large Wind Power Turbine Casting Iron Hub
Wind power casting hub is a key component of wind power equipment. It connects the blade and the main shaft. Its function is to bear the thrust, torque, bending moment and gyro moment of the wind on the blade, and then transmit the torque of the wind wheel to the mechanism.
The hub has a special structure, complex shape, large volume and difficult processing. Generally ductile iron castings, made of QT400-18AL, have strict requirements in terms of mechanical properties, metallographic structure, and chemical composition. They must undergo ultrasonic and magnetic particle inspections, and no shrinkage, cracks, cracks, pores, and slag inclusion defects are allowed. .
