Kinetics of Liquid-Phase Reduction of Iron by Disperse Solid Carbon

摘要

A new method of kinetic analysis of the liquid-phase reduction of iron by disperse solid reducing agent is proposed; in this method, the reaction constant per reducing-agent particle is determined. It is established experimentally that, in the reduction of iron from slag by disperse graphite of two different fractions, the reaction is of first order with respect to (FeO). It is shown that the apparent reduction rate constant of iron oxides in slag melt, with the participation of disperse solid reducing agent, depends not only of the particle size but also on the degree of melt mixing.
