Abstract

The effect of thickness of vortex gating system on microstructure, velocity and porosity of A314 cast alloy was investigated. Three different thicknesses of 20, 25 and 30 mm were simulated and casted. The data of simulation showed the thicker gating reduced the velocity of the melt. In addition, increased thickness in vortex gate contributes to better eutectic interlaminar spacing. The best quality of casting (less porosity) was obtained with large thickness of vortex gating system.
