| Abstract: | <p>The slag metal emulsion may play a significant role in the global furnace decarburization kinetics in oxygen steelmaking. In recent years, the important interaction between droplet generation rate, droplet residence time in slag and droplet decarburization rate has become more evident in the literature. The decarburization kinetics of Fe-C-S droplets in CaO-SiO2-MgO-FeO slags were investigated for highercarbon droplets (approximately 4.2 % C). The effect of slag FeO, droplet mass and Sulphur content on decarburization rate were evaluated. The limit between external and internal nucleation of CO gas was investigated. A model was developed for prediction oftime to the onset of carbon boil.</p> |
