Abstract [en]

This paper presents a three-dimensional numerical model simulating fluid flow, heat transfer and concentration distribution in 105t steel ladles before and during casting. The model was developed by combined implementation of a numerical simulation package, TEMPSIM, and a computational fluid dynamics (CFD) simulation package, PHOENICS. In this study, TEMPSIM was used to calculate the heat transfer in ladle linings and predict the heat losses from the steel melt to the linings which are transient and sensitive to ladle configurations. These data were used as input into PHOENICS for CFD modeling of fluid flow and heat transfer as well as transport of six tracer elements in steel bath in the ladle. The modeling results were compared with concentrations measured in an industrial experiment where six tracer elements were added at different positions in the ladle and at different times before and during casting. With the use of this model, the stratification phenomenon and the effect of drainage flow, as well as the behavior of added tracer elements, in the steel ladle during the casting period, were described and discussed.
