Numerical Simulation and Optimization in Solidification of Zinc Alloy
Numerical method was used to simulate the solidification process of zinc-aluminum alloy Zamak 5, shrinkage porosity of the zinc-aluminum alloy ingot with big diameter (114mm) was simulated using the shrinkage criterion, orthogonal test was designed to analysis the influence of different casting parameters as casting temperature, preheating temperature of the mold and the heat transfer coefficient between the mold and the environment. The result shows that the shrinkage value was minimal when the casting temperature was 480, the preheating temperature was 200 and the heat transfer coefficient was 200.
