抄録

Sequential casting of different steel grades with a level DC magnetic field (LMF) has been performed by 8-ton scale pilot casting machine. According to the results of casting experiment it has been clarified that the mixing length at the ladle change region decreased with LMF and was affected by density difference of molten steel between the first and the second ladle. The fluid flow phenomena in strand pool with LMF and the mechanism of the difference of mixing behavior by density difference have been elucidated by numerical analysis. Moreover the criteria of stability in the strand pool has been proposed in consideration with temperature and solute difference of molten steel between the former and the latter ladle.
