Study on the Technology and Defects in Low-Pressure Semi-Solid Die Casting of Aluminum Alloy Wheel Hub

Abstract:

Technology and defect in the low-pressure semi-solid die casting of aluminum wheel hub under different process has been studied. The simulation software ADSTEFAN 2012 is used to analyze the solidification in different die temperature. Stereomicroscope, digital camera and optical microscope (OM) are used to study defect in the casting. The result shows that the low slurry temperature (606°C) will result in higher viscosity, and the low preheated die temperature will increase the cooling rate so that shrinkage is formed in the isolate solidification area. In the technology of casting wheels, the optimum temperature of the slurry is 614°C, preheated temperature of die is 400°C.
