Abstract

See full text

A method for producing liquid pig iron or liquid steel intermediate products from fine-particled material containing iron oxide. The fine-particled material is prereduced in at least one prereduction stage and reduced in a final reduction stage to sponge iron. The sponge iron is melted in a melt-down gasification zone, with carbon carriers and oxygen-containing gas supplied. A CO- and H2-containing reduction gas is generated and introduced into the final reduction stage, is converted there, is drawn off and introduced into at least one prereduction stage, converted there and drawn off. A first quantity fraction of the fine-particled material containing iron oxide is introduced into a melt-down gasification zone via at least one prereduction stage and one final reduction stage, and a further quantity fraction of the fine-particled material containing iron oxide is introduced into the melt-down gasification zone directly or together with the carbon carriers and the oxygen-containing gas.
