Cold model study of the surface profile in a continuous slab casting mold : Effect of second phase

Most of the water modeling work carried out so far has simulated only the flow of liquid steel, without any slag phase. But, in the actual system, a flux layer is used to cover the meniscus. Only a few investigators have made an attempt to simulate the slag phase over the metal. Sobolewski and Hurtuk used cork pieces in their water model to simulate the slag entrainment in the melt. Tanaka et al. made water modeling studies using oils as the second phase. They studied the vortex depth formed at the oil-water interface. The present work aims to characterize the complete meniscus profile in the presence of a second phase.
