Abstract
A method for producing a refined aluminum alloy according to an embodiment of the present invention includes a first heating step of heating a starting material of an aluminum alloy alone at a heating temperature at or above a liquidus temperature of the aluminum alloy to obtain a liquid melt, a cooling step of cooling the liquid melt at a cooling temperature below the liquidus temperature and at or above a solidus temperature of the aluminum alloy and producing aluminum alloy particles and sludge to obtain a semi-coagulated melt, a second heating step of heating the semi-coagulated melt at a heating temperature at or above the liquidus temperature and at or below a dissolution temperature of the sludge to melt the aluminum alloy particles, thereby producing a refined liquid melt to obtain a sludge-containing liquid melt, and a recovery step of recovering the refined liquid melt.
