FIELD: metallurgy.
SUBSTANCE: method involves steel making in a steel-making unit, pouring of molten metal into a ladle, examination of molten metal chemical composition, alloying, deoxidation, vacuumising and casting. Alloying and deoxidation of molten metal is performed additionally with rare-earth metals and/or their alloy combinations. Nitrogen alloying is performed before deoxidation is completed by introduction to the ladle of solid nitrogen-containing materials and/or by gaseous nitrogen blowdown, and total amount of deoxidising agents, which is introduced to the molten metal to achieve the specified content of oxygen in steel, is determined as per the following formula: ΣR=1.2÷3.0(ao-[%O"ГОТ"], where ΣR - total content of deoxidising agents, wt %, ao - oxygen activity in molten metal, wt %, and [%O"ГОТ"] - specified oxygen content in steel, wt %.
EFFECT: invention allows improving quality of molten steel, reducing the content of non-metallic inclusions and improving mechanical and operating properties of steel.
