Functions of Step Gating System in the Lost Foam Casting Process
In order to explore whether the step gating system played a role in lost foam casting (LFC) process,this paper simulated the mold filling process of a step gating system with an auxiliary sprue and three side ingates by using the gravity LFC model of the code FLOW-3D,and analyzed its mold filling characteristics in LFC.It is found the mass flux ratio through the bottom-side ingate exceed 82% the total mass flux,much more than through the others.And it is also found the metal temperature of the middle region in the height direction is lower than the upper region or bottom region.The results show that the step gating system is not able to achieve its main roles in LFC.Our results can be used to design gating system in LFC.
