The objective of research is to define aluminium and its production wastes melting modes in electric unit while applying protective fluxes layer. This article cites the results of researches on development of flux structure for melting of aluminium production wastes. Melting unit diagram and results of research defining aluminium production wastes melting temperature regime are exemplified. Modes of metal charging, heating-up and melting of aluminium and its production wastes are exemplified for the electric unit with movable upper and immovable lower electrodes. The article describes the results of researches and recommendations that smelting chamber temperature to be maintained in the range of 1000-1100 °С, with melting zone temperature at 1400-1500 °С. It is recommended that charging of production wastes slag was carried after flux melt and reached 700-750 °С. Tables cite fluxes compositions that allow conducting aluminium melting process in various units. In the conclusion it is stated that application of a corresponding design of melting unit in aggregate with graphite electrodes and protective fluxes provides: - reduction of irretrievable metal burn-off losses; - savings on energy expenditures; - quality upgrade of liquid smelt due to decrease of oxide inclusions and occluded gas concentration.
