FIELD: metallurgy, possibly steel melting, particularly steel killing in ladle, in steel melting aggregate and in aggregate for out-of-furnace treatment of steel.
SUBSTANCE: process comprises steps of adding aluminum to melt steel; using aluminum in the form of ferroaluminum containing 20 - 40% of aluminum with substitution factor in relation to secondary pig aluminum 1.2 - 1.6 and with lump size 20 - 80 mm. It provides total consumption of aluminum lowered by 1.2 - 1.6 times.
EFFECT: improved assimilation of aluminum, lowered total consumption of aluminum.
