Direct Observation of Molten Steel Meniscus in CC Mold during Casting

Abstract

Free surface fluctuations of molten steel in the mold of a continuous caster are considered to have a significant effect on the surface quality of the cast. To find out the relationship between the surface wave motion of molten steel near the mold wall during casting and mold oscillation, the meniscus of molten steel in the mold was directly observed through a quartz glass window mounted on the mold wall. As a result, it was confirmed that the meniscus fluctuates at the same period and phase as those of the mold oscillation.
