In steel making processes, the level of impurities in the product is affected by the interplay between molten iron and molten slag. An accurate measurement of interfacial tension is necessary in order to understand the interfacial phenomena and to improve the quality of steel products. By oscillating a levitated core-shell-structured droplet of molten iron (core) and molten slag (shell), the interfacial tension will be measured using the electrostatic levitation furnace in the international space station. This research investigates the influence of test parameters, such as the radius ratio of core and shell, off- and in-phase oscillation, thermophysical properties of molten slag, and the eccentricity of core and shell on the measured interfacial tension.
