FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy, particularly, to alloying of steel by nitride and carbonitride nanophases of alloying elements. Alloying materials together with carbamide are added into ladle with steel, total consumption of carbamide making 0.8 kg per ton of steel. Addition of alloying materials is effected in compliance with alloying process as follows: aluminium - 1.8 kg/t along with carbamide in amount of 0.5 kg/t, ferrovanadium - 0.8 kg/t, and silicon manganese - 4.0 kg/t along with carbamide in amount of 0.3 kg/t.
EFFECT: notable increase in steel quality.
