Abstract
Procedure for the manufacture of liquid pig iron with simultaneous obtaining of a gas mixture that is used for the previous reduction of the mineral used, characterized in that a carbon vehicle is introduced together with a reactive medium in the deep zone of the bath, binding the carbon to the iron and the bath being supersaturated with carbon, and because in a contiguous area of the bath subjected to continuous mixing, the carbon surplus is transformed into carbon monoxide by insufflated oxygen, while the mineral previously reduced, at least partially, in An adjoining reaction chamber by means of the produced reduction gases is delivered to the vicinity of the exothermic reaction zone and melts.
