FIELD: metallurgy. SUBSTANCE: apparatus has final reduction furnace with fluidized bed and melting gasificator connected to final reduction furnace. The latter has plurality of iron ore fines discharge openings. Lumpy coal is charged into melting gasificator so as to define compacted coal layer, into which reduced iron ore fines are delivered from final reduction furnace. Side wall of melting gasificator is provided with charging openings connected vis channels to openings of final reduction furnace, so reduced iron ore fines are continuously discharged from furnace and charged into compacted coal layer in melting gasificator. Apparatus is employed in molten iron production unit using coal and iron ore fines. EFFECT: increased efficiency and reduced loss of iron ore fines by direct charging of coal and reduced iron ore fines into melting gasificator. 11 cl, 3 dwg
