底吹き液体噴流によって撹拌される円筒浴の旋回運動に及ぼすスラグの影響

摘要

Model experiments were carried out to understand the effects of slag on the swirl motions of a molten steel jet generated through a centered bottom nozzle. Two types of swirl motions were observed. One appeared when the silicone oil layer was thin, while the other appeared when the silicone oil layer was thick. The starting time, damping time, period and amplitude of the two swirl motions were investigated and correlation methods of them were proposed.
