ABSTRACT:
A process for the direct production of sponge iron particles and liquid pig iron from lump iron ore is described, in which the iron ore is reduced as a loose bed in a direct reduction unit by means of hot reducing gases to sponge iron and is subsequently melted in a melting gasifier by means of the introduced carbon and blown in oxygen-containing gas, accompanied by the production of reducing gas. At least part of the reducing gas, after cooling to the temperature necessary for reduction, is introduced into the reduction zone of the direct reduction unit. A considerable part of the carbon and reducing gas is provided by a mixture of hydrocarbon-containing plastic and petroleum coke and/or coke (fines). The reducing gases are primarily at least partly obtained by cracking from the plastic and by thermal gasification from the coke.
