Investigation of Two Immiscible Liquids Wetting at Elevated Temperature: Interaction Between Liquid FeMn Alloy and Liquid Slag

Abstract The goal of the current work is to develop a methodology study wetting behaviour two immiscible liquids at high temperatures, and investigate parameters which influence properties. between synthetic FeMn alloy slag has been investigated using sessile drop technique. Two experimental procedures were implemented under both Ar CO atmospheres: (a) placed next each other on graphite substrate; (b) one droplet dropped top other. FactSage applied calculate reactions their equilibrium. presents demonstrates suggested methodologies. results indicate that relatively stable temperatures up 100 K above melting points, regardless size atmosphere. MnO reduction accelerated higher temperature, especially in CO, thus increasing slag, eventually fusing together. At even separates from due changing chemical composition during non-equilibrium reduction.
