Abstract
Filling process of vacuum die casting magnesium alloy steering gear was simulated by numerical simulation to understand the filling characteristics of liquid metal under the high vacuum conditions. Based on the simulated results, the filling and solidification of the alloy at high vacuum, low vacuum and conventional die casting were analyzed comparatively. The results show that filling capacity of liquid metal can be improved effectively with increasing in the vacuum degree, eliminating the gas hole defects in the steering gear, however, it is not related to the shrinkage porosity (hole).
