Semi-solid die casting instead of conventional casting was used to produce bearing cage, Model of semi-solid die-casting was established based on power cut-off (PLCO) model and ProCast 2008 to simulate the effects of processing parameters on deformation process, through orthogonal experiment and analysis of defects, the reasonable technological parameters for using A356 aluminum alloy to finish semi-solid die casting of bearing cage were obtained: the pouring temperature was580°C, the preheating temperature of the mould was 200°C, and the injection velocity was 20 mm/s.

A two-dimensional model coupling of the electromagnetic field, the temperature field and the flow field of preparation of A356 aluminum alloy semi-solid slurry by electromagnetic stirring (EMS) was established. The Power Law Cut-Off (PLCO) model was used to model the semi-solid slurry. The effect of process parameters such as stirring frequency, stirring current, pouring temperature and crucible preheated temperature on the electromagnetic field, temperature field and flow field were investigated by finite element code ANSYS combined with secondary development INTEL FORTRAN software and corresponding experimental verification. The results show that the electromagnetic field and flow field increase as stirring frequency and stirring current increase. Similarly, temperature field and flow field increase as pouring temperature and crucible preheated temperature increase. However, too high stirring frequency, stirring current, pouring temperature and crucible temperature may lead to rapid increase in the flow field, as a result, strongly turbulent flow might occur. The reasonable process parameters for preparation of A356 alloy semi-solid slurry by EMS were obtained. The simulation results are significantly approved with corresponding experimental ones, that verifying the reliability of the calculation models and the software algorithm.
