Abstract：The filling and solidification of large-size A356 aluminum alloy hub castings produced by low pressure casting were simulated for three pouring process schemes, namely, single runner, double runner and triple runner. According to the simulation results, the defect distribution, filling efficiency, grain radius and entrainment of the three process schemes are compared. The results show that the triple runner process not only improves the quality of the hub and reduces the defects, but also greatly shortens the production time, which is a potential new process.
