FIELD: metallurgy.
SUBSTANCE: steel microalloying by boron is performed at output by the addition to the ladle of the aluminium and complex alloy of ferrosilicon boron in amount of 4.0-7.5 kg/t of steel with ratio of aluminium to ferrosilicon boron within range (0.25-0.50), at that the ferrosilicon boron contains in wt %: 60-65 Si and 0.5-2.0 B.
EFFECT: reduced expenses for metal production, reduced time of out of furnace treatment at ladle-furnace unit, and increased quality of the metal products.
