FIELD: metallurgy.
SUBSTANCE: claimed method includes reducing of metal fines to produce prereduced metal fines with free carbon excess. Prereduced metal fines in hot state are transferred into electric arc furnace bath in inert gas curtain. Molten metal in bath is agitated to prevent crust formation on bath surface. Then prereduced metal fines are fused in electric arc furnace to produce target product.
EFFECT: optimized process for crude iron melting in electric arc furnace.
