Abstract

An understanding of the dynamic behaviors of poorly-wetted fine particles penetrating into molten steel is of essential importance for the enhancement of steel refining efficiency. Many water model experiments have been carried out on a poorly-wetted single sphere penetrating into molten steel. Information on the behaviors of more than two particles, however, is very limited. In this study, the behaviors of a pair of spheres penetrating into a water bath are observed with a high-speed camera. Particular attention is paid to an air cavity or air cavities formed behind the spheres because the cavity length affects the penetration depth which is closely associated with the refining efficiency.
