N2 - It is important to know the behavior of jets from a top-blown lance in order to control the reactions in the converter. However, there are few studies on the jet characteristics under incorrect expansion and the interference behavior of multiple jets. In this study, the characteristics of jet under incorrect expansion and the interference behavior of multiple jets were investigated by experiments using a cold model. Furthermore, hot model experiments using a 6 t converter were conducted in order to investigate the correlation between the velocity of jet and dust generation. There is good correlation between dust generation and the velocity of jet, and dust decreases by utilizing incorrect expansion for soft-blow.
