Summary: | PROBLEM TO BE SOLVED: To provide a melting method of an aluminium material capable of melting surely the aluminium material, and improving greatly a metal recovery rate; and to provide a melting unit of the aluminium material.SOLUTION: A molten salt flux layer 20 comprising molten salt flux containing at least KCl, NaCl and cryolite is formed on molten aluminum 3, and an aluminium material 1 is fed on the molten salt flux layer 20, to thereby melt at least a part of the aluminium material 1, while the aluminium material 1 is settling down in the molten salt flux layer 20.SELECTED DRAWING: Figure 3
【課題】アルミニウム材を確実に溶解することができ、メタル回収率を大幅に向上することが可能なアルミニウム材の溶解方法、及び、アルミニウム材の溶解装置を提供する。【解決手段】アルミニウム溶湯3の上に、少なくともKCl及びNaClと氷晶石とを含有する溶融塩フラックスからなる溶融塩フラックス層20を形成し、アルミニウム材1を溶融塩フラックス層20の上に投入し、アルミニウム材1が溶融塩フラックス層20内を沈降している間に、アルミニウム材1の少なくとも一部を溶融することを特徴とする。【選択図】図3 |
