Title: Production of pig iron
Inventor: PAPST GERO
IPC: C21B13/14
Filed: 1986-01-20
Abstract: A process for the production of pig iron from fine ore is described, in which initially the fine ore undergoes prereduction to a degree of metallization of preferably 65 to 75%. The sponge iron obtained is then melted down and under goes a final reduction. This process takes place in a melting cyclone 2, to which the sponge iron is supplied by means of a central opening 1 and into which are tangetially blown via a lateral opening 3 a carbon carrier, an oxygen-containing gas and optionally fluxes. As a result of the angular momentum produced, the sponge iron particles are deflected to the side and melted and finally reduced by the combustion gases of the carbon carrier. The molten iron collects in an iron bath 8. The gas produced in the melting cyclone is cooled from approximately 1500 DEG  C. to approximately 800 DEG  C. in a waste heat system 10, as well as by admixing cooling gas supplied via a line 11 and is then used for the prereduction of the iron ore.
