Study of Two Phase Emulsion Systems

Two phase emulsion is widely used to increase the reaction efficiency. Slag–metal emulsion is used widely in metallurgy to increase the efficiency of the process. Previously, Pb–salt emulsion system at high temperature has been studied experimentally and mathematically. In this work the study has been extended to Al–salt and Sn–salt systems to cover wider physical properties at much higher temperature, both experimentally as well as mathematically. Further the mathematical model has been verified against various published emulsion systems, having a wide variety of physical properties. Using this model, the effect of various physical properties of slag and iron, such as viscosity, density and drop size, on the iron–slag emulsion system has been studied. It is found that the iron droplets of the size of 100 µm or lesser may be entrapped in the slag if sufficient time is not allowed to settle them into the metal phase.
