FIELD: metallurgy.
SUBSTANCE: invention relates to the composition of the charge for ferrosilicoaluminium melting derived from substandard raw materials-bauxite and alumina used for complex deoxidation of steel. The charge contains, wt %: alumina bauxites 31.0-41.0, quartzite 35.0-45.0, coke 23.0-25.0.
EFFECT: invention makes it possible to increase the purity of ferrosilicoaluminium by undesirable impurities of non-ferrous metals and to reduce its cost by eliminating the metallic component from the composition of the charge without reducing the aluminium content in the resulting alloy.
