Behavior Comparison of (Al, Pb, Sn)–Molten Salt Emulsions Involving Gas Bubbling

Abstract

In a steelmaking process, metal droplets are emulsified into slag and this phenomenon is called “metal emulsion” Metal emulsions have great potential for improving the reaction efficiency in the steelmaking process. In our previous studies, emulsion formation was experimentally evaluated using a low-melting-point metal and a chloride salt, and the influence of the gas flow rate on emulsion formation was clarified. In this article, the results of previous studies are first summarized and then compared with the results obtained for other systems; finally, empirical equations are proposed.
