Abstract

At present, interfacial phenomena between molten steel and oxides, usually called slag or mold flux, play an important role in steel processing for material design. Therefore, understanding interfacial tension is important for process control. From this, we propose an interfacial tension measurement technique between molten steel and oxides using a modified oscillating drop method with levitation techniques. The interfacial tension data using traditional techniques based on the sessile drop method have been obtained only at temperatures around the melting point of iron due to dissolution of containers and the substrate into molten steel and oxides in higher temperature regions. Our proposed technique to obtain the temperature dependence of interfacial tension between molten iron and oxides is to use a core-shell form droplet including an interface between two liquids using electrostatic levitation, which negates the use for containers. The experiment was performed on the International Space Station using the electrostatic levitation furnace (ELF) in the KIBO module.
