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.

在钢化过程中，反应的界面面积扩大很重要。在这项研究中，研究了有效形成金属乳液的状况。在实验中，Al，SN和Pb用作金属相，氯化盐用作矿渣相。研究了气体流量和物理特性对乳液形成的影响。通过高速摄像头观察到金属乳液形成的现象，最后是经验方程式的。
