FIELD: metallurgy.
SUBSTANCE: method includes mixing initial charge components based on secondary aluminium production wastes and a binder, subsequent moulding of the mixture. When mixing, sodium aluminate is used as a binder, and a reinforcing component in the form of borosilicate glass fibre is additionally introduced in the amount of 0.3-3.6 wt %. The produced mixture is briquetted, the ready briquettes are placed in a sealed container with a gas-discharge path, and consumption of the binder depends on specific surface of the secondary aluminium production wastes and determined according to empirical equation.
EFFECT: invention makes it possible to produce a complex steel melting flux with low energy consumption and high strength properties of briquettes with simultaneous stabilisation of refining slags.
