FIELD: metallurgy.
SUBSTANCE: method includes partial restoration of iron oxides in hard state in tank for prior restoration, melting of partially restored iron oxides to melted iron in tank for direct melting. During direct melting side gas containing sulfur is formed, which is let out from direct melting tank. First flow of side gas is used, which is let out of tank at prior restoration stage for prior restoration of iron oxides in tank for prior restoration. Second flow of side gas is used, which is let out from air heating tank or oxygen-saturated air prior to feeding to direct melting tank.
EFFECT: removed undesired admixtures.
