Abstract
The flow pattern of molten steel in a slab continuous caster mold is very important for removing the nonmetallic inclusions in the molten steel and preventing the entry of mold flux/slag into the molten steel. Different flow patterns are created by different operating conditions and submerged nozzle configurations. In this study, a three dimensional analysis system for turbulent fluid flow problems with free top surface has been developed to numerically simulate the molten steel flow in the mold. It can evaluate the effects of operating condition and nozzle design on the flow pattern and thus on the flotation of inclusions and flctuation of melt surface layer. The results of the simulations are very useful in determining the optimum operating condition and submerged nozzzle design to obtain cleaner continuous by cast slabs.
