A new integrated CFD-combined reactors approach is proposed for the description of flow in metallurgical vessels. CFD simulations were used to obtain the melt flow pattern in the vessel (ladle, tundish, or continuous caster mold). From these were derived the residence time distribution curves (for flow-through systems, e.g. at tundish exit). Mixing curves were derived for closed systems (e.g. ladle). In the next step, the melt flow was represented as a “combined reactors” system consisting of a combination of unit reactors (Plug Flow, Mixer, and Recirculated Volume). An inverse simulation was used to define the volumes of the unit reactors and the melt flow rates between them by fitting to the curves from the CFD. The suggested approach is demonstrated for multiple tundish and SEN designs, and for Ar-stirred ladles. This methodology can be used to enhance traditional post-processing CFD analysis and also as a tool for on-line process control.
