    摘要: A method for refining molten Al alloy and a non-halogen based flux for refining molten Al alloy which make it possible to perform refining such as removal of gas and inclusions at a high reduction level, and are free from a problem that the flux remains in the molten Al alloy, wherein a refining flux is injected into molten Al alloy obtained by melting an Al raw material to refine the melt, thereafter, the resultant is supplied to a mold, so as to cast the Al alloy. At this time, alum is used as the refining flux.
