FIELD: metallurgy.
SUBSTANCE: invention relates to the method of and device for aluminium and its alloys affinage against electropositive admixtures. Device contains container with hearth lined with refractory materials, for installation of the melted aluminium alloy with electropositive admixtures and melted affinated aluminium, one or several porous membranes impregnated with electrolyte, impermeable for the melted aluminium alloy with electropositive admixtures and permeable for the electrolyte and aluminium cations, to separate the melted aluminium alloy with electropositive admixtures, used as anode with current lead, and melted affinated aluminium as a cathode with current lead, and at least one hydromagnetics agitator of the anode melt, installed at the border porous membrane-anode melt. Besides the method of aluminium and its alloys affinage from the electropositive admixtures is described.
EFFECT: assurance of increased cleaning degree.
