Abstract
The length of the transition slab may be decreased by manipulating differences in temperatures or densities of new and old grade steels. The molten steel liquidus temperature and density are related to the composition. For most elements in steel, both the liquidus temperature and density of the molten steel decrease with an increase in their mass fraction. Therefore, the temperature and density of molten steel cannot simultaneously shorten the transition slab. This study compared the effect of temperature and density on the length of the transition slab using numerical simulation methods based on flow, heat transfer, and mass transfer. The model was verified using a physical simulation and an industrial experiment. Finally, the effects of temperature and density on the transition slab length were elucidated.
