FIELD: metallurgy.
SUBSTANCE: invention relates to steel melting out of iron-ore iron-rich pellets in arc furnace. are supplied continuously to the metal evaporation zone, created upon contact of the electric arcs with melted metal, and their melting is performed with assurance of the optimal waste of metal in said zone considering ratio of iron-ore iron-rich pellets consumption in said zone with parameters of heat state of slag-metal bath of the furnace.
EFFECT: reduced waste of metal in furnace, increased production of good steel, and reduced power consumption for pellets melting in the furnace.
