Research Abstract

In the steelmaking process, an enlargement of interfacial area for reaction is important. In this study, the condition of effective formation of metal emulsion was investigated. In experiment, Al, Sn, and Pb were used as metal phase and chloride salt was used as slag phase. The effect of gas flow rate and physical properties on the emulsion formation was investigated. The phenomena of the formation of metal emulsion were observed by high speed camera, and finally the empirical equation wasproposed.
