Abstract

A method for producing iron containing products includes: operating a blast furnace plant to produce liquid pig iron from blast furnace charge material, whereby metallurgical gas having blast furnace top gas is generated; operating a direct reduction plant to produce direct reduced iron products from iron ore loaded into the top of a direct reduction furnace, a stream of reducing gas being introduced into the direct reduction furnace, the direct reduction plant including a reformer or heater device from which the stream of reducing gas is discharged, whereby top gas is generated by the direct reduction furnace; where a first stream of direct reduction plant top gas is treated in an enriching stage configured for enriching in reducing species, and forwarded to the blast furnace plant to be used therein as reducing gas; and where a first stream of the metallurgical gas (B3/B6) is forwarded to the reformer or heater device of the direct reduction plant to be used therein as fuel gas. Also disclosed is a corresponding metallurgical plant.
