Abstract

During solidification, macrosegregation of alloying elements results in inhomogeneous properties of cast product. Segregation level of alloying elements is different because of the difference in solubilities. It is required to study the distribution of all alloying elements as it affects microstructure evolution during subsequent processes. In the present study, a numerical model is developed to predict the segregation of multicomponent (Fe–C–Mn–Si) alloy steel during solidification in a round billet continuous caster. The distribution of individual alloying elements is calculated by solving coupled turbulent flow, energy and species conservation equations. Solidification is considered to be governed by Lever rule and the liquidus temperature varies with local composition. Segregation index is then determined by calculating ratio of final to initial carbon equivalent at the center of cast billet. Casting speed and pouring temperature are parameterized to study their effect on solidification profile and segregation.
