The Kinetics of Reduction of MnO in Molten Slag with Carbon Saturated Liquid Iron.

Abstract

This investigation devotes to the kinetics of the reduction of (MnO) with carbon-saturated liquid iron. The experiment condition involves high content realm of both ("I.MnO) and "/oMll It was found that the reduction is limited by the interfacial reaction. By means of a X-TV dynamic metallurgical phenomena displaying device, the slag-iron interface was proved to be the essentiai site for evolving the reduction product CO. The content variation of surface active agent ~affects obviously on the reduction rate. If no carbon is added in slag, then a hump emergeson the curve of ('10FeO) vs, reaction time. In this case, the apparent reaction order is 2, If there is a carbon addition in siag, the process is of apparent first order. Based on the three step modelof reactions in series, the aforementioned phenomena and regu larities were elucidated unitedly.
