FIELD: metallurgy.
SUBSTANCE: invention relates to methods for reducing iron oxide to metallic iron at a plant with full metallurgical cycle of production, where there is a coke furnace and/or a steel-melting furnace with oxygen supply. More specifically, the present invention relates to methods for reducing iron oxide to metallic iron using COG coke gas or COG and gas from main steel-melting furnace with BOFG oxygen supply.
EFFECT: invention is aimed at maximization of iron amount of direct DRI reduction, hot iron of direct reduction of HDRI or hot briquetted iron HBI, which can be produced from a predetermined amount of COG or BOFG, while minimizing the equipment.
