In any casting plant the melt treatment is the most important process because the effectiveness of the treatment determines the quality of cast product. Effective handling of the molten metal is key to successful casting of the alloy. The amount of an alloying element present in alloy and how the melt is treated, have a considerable impact on the mechanical properties and, consequently, the quality of the castings. The properties of these alloys are dependent on the degree of refinement of the microstructure and melt treatment Generally the molten casting alloy is contaminated with inclusions, oxides, slag, insoluble materials and dissolved gases. For effective treatment various process like fluxing, grain refinement and degasification are performed. The degasification is a process to remove the dissolved gases from the molten material. In this paper influence of various degasification process variables for the removal of hydrogen gas from molten aluminum alloy are investigated through experimental work and the impact of degasification on quality of cast products is examined.
