Zusammenfassung:Disclosed is a steel-producing mill comprising, instead of a usual blast furnace, a direct reduction plant in combination with a meltdown gasifier as a pig iron source. The mill is operated in combination with a single steel converter. The direct reduction plant, on its discharge side, is connected both with the meltdown gasifier and with the steel converter via sponge iron transporting devices. The meltdown gasifier communicates with the steel converter via a transport line for molten pig iron. As the solid charge in the refining process, sponge iron is exclusively used.
