Refining flux FOR REMOVAL magnesium from aluminum alloys

摘要

FIELD: metallurgy.;SUBSTANCE: flux for fining of aluminium alloys from magnesium contains following components, wt %: sodium chloride 15-25, potassium chloride 15-25, fluorsilicate sodium 10-25, mixture of cryolite and fluoric aluminium 60-25, herewith cryolite and fluoric aluminium are contented in flux in the form of mixture with cryolite ratio 0.9-1.7. In particular cases of invention implementation in the capacity of cryolite component there are used fluoride-carbonic products of wastes processing of aluminium manufacturing.;EFFECT: it is increased effectiveness of flux fining of aluminium alloys from magnesium at manufacturing of repeated nonferrous metals.;1 tbl, 5 ex
