New Method and Experimental Study for Fast Evaluating Filling Mould Ability of Al-Si Alloy by Surface Tension

Abstract

On the basis of analyzing the relationship between filling mould ability and surface tension of Al-Si alloy, a new method was put forward that filling mould ability can be fast evaluated by surface tension. To fast test surface tension of Al-Si alloy in front of furnace, a new apparatus had been developed and a new mould had been designed to appraise the ability of filling acute angle of Al-Si alloy by authors. By means of the self-developed new apparatus and new mould, the relationship between surface tension and filling mould ability had also been proved and gotten by many experiments on Al-Si alloys. Depending on the relationship the filling mould ability of Al-Si alloy can be evaluated by surface tension in few seconds before cast.
