Study on the Grade-Controlled Filling of Vacuum Counter-Pressure Casting Thin Wall Aluminum Alloy

Abstract:

The grade-controlled filling behavior of vacuum counter-pressure casting thin wall aluminum alloy was studied by numerical simulation and experimental investigation. According to the analysis of filling behavior under fixed pressure and the casting structure, the technology of the grade-controlled filling of vacuum counter-pressure casting thin wall aluminum alloy was suggested. The result shows that the filling velocity was controlled on grade, resulting in the smoothly and sequential filling behavior, and the decreasing of defects in castings.
