ABSTRACT

Model experiments were carried out to investigate the motion of nonmetallic inclusions moving through a slag-steel interface and the resultant deformation of the interface. Silicone oil and water were used as the models of slag and steel, respectively. As the models of the inclusions, solid spheres made of three different materials were employed. The behavior of a solid sphere approaching from the top of a horizontal silicone oil-water interface and subsequently passing through the interface was recorded on a high-speed video camera. The fall velocity of the sphere, amount of silicone oil accompanied by the sphere descending in the lower water layer, the size of the deformed interface were determined using an image-processing technique. The adequacy of a semiempirical equation derived previously for the critical diameter of a sphere being in equilibrium at a horizontal liquid-liquid interface was examined. The effect of the wettability of sphere materials on the behavior of the interface was also discussed.
