METHOD FOR REPROCESSING OF JUNKS OF MAGNESIUM CONTAINING BASED-BASED ALLOYS Russian patent published in 2005 - IPC

Abstract RU 2244027 C1

FIELD: non-iron metallurgy, in particular reprocessing of aluminum waste.

SUBSTANCE: claimed method includes junk charge into premelted flux at ratio of 1:(5-10); heating up to melt temperature; smelting under flux layer, and separation of metal from flux. Equimolar mixture of sodium chloride and potassium chloride with addition of 2.9-52.6 % (in respect to total flux weight) magnesium fluoride is used as flux, and in melting process flux layer with thickness of 4.5-20 cm is maintained. Method affords the ability to conserve original composition and eliminate additional burdening with magnesium.

EFFECT: decreased burn-off loss, especially for magnesium, metal of improved quality.
