FIELD: metallurgy.
SUBSTANCE: into content of fining flux for removing of magnesium from aluminium alloys, containing chlorides of alkali metal, fluorsilicate sodium and cryolite, it is introduced additional amount of cryolite. Additionally cryolite ratio in mixture of cryolite and fluoric aluminium is equal 0.89-0.67. Particular ratio of flux components provides increasing of reagent amount (AlF3) in flux. Content of fining flux provides elementary discharge per 1 kg of extracted magnesium at the average for 1.65 kg lower, than the other similar flux.
EFFECT: process simplification of fining, saving rate and removing of magnesium from all aluminium alloys, which are manufactured at plants of second nonferrous metals.
