Abstract
The kinetics of reactions between drops of Fe-C, Fe-C-P and Fe-C-S alloys and synthetic oxidizing slags at 1550°C have been studied. The reaction kinetics are obtained either from chemical analysis of quenched samples, or, for decarburization, * by continuous measurement of the flow rate of evolved gas. The marked effect, on the kinetics, of the metal emulsification during carbon removal is evidenced. A decrease in slag oxygen potential results in the slow-down of decarburization. Sulfur shows a tendency to limit interfacial reactions, but it enhances metal emulsification. Both mass transfer processes and interfacial reactions, as well as nucleation, are believed to play their part on the rate of decarburization.
