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. .
