<p>In a process for producing liquid pig iron (13) or liquid metallurgical preparations from starting materials which consist of preferably lump-shaped and/or pellet-shaped iron ore (4) and if required flux powder (5), the starting materials are directly reduced into sponge iron in a reduction region (2), the sponge iron is loaded into a melting and gasifying region (12), where it is molten together with carboniferous substances (10) and oxygen-containing gas, generating a CO- and H2-containing reduction gas which is extracted from the melting and gasifying region (12) and led into the reduction region (2), where it is reacted and extracted as top gas, the top gas being scrubbed and the thus produced sludge being at least partially agglomerated. In order to utilise the thus obtained agglomerates with the lowest possible energy consumption, they are recycled in the reduction region (2).</p> |
