FIELD: metallurgy; production of wide range of steels in electric-arc steel melting furnaces.
SUBSTANCE: proposed method includes forming molten phase on furnace hearth followed by blowing the metal with inert gas through holes in hearth located in one vertical axis with electrodes; before tapping of metal, intensity of blowing is increased from 0.13 to 0.35 m3/h.
EFFECT: reduction of melting losses; reduction of specific consumption of inert gas for mixing molten-metal pool.
