Abstract
The mechanism of reduction of iron and chromium oxide from synthetic e lectric are furnace stainless steelmaking slags has been studied. The activation energy for reduction of FeO depends on the FeO content of t he slag and the nature of the product formed. The rate of reduction of both FeO and Cr2O3 is controlled by diffusion of ions in the slag pha se. The reduction of Cr2O3 primarily takes place at the slag/Fe-C drop lets interface. IS/1352b.
