Nonmetallic inclusions in molten steel can result in poor quality of a continuous casting product. In addition to being used as the reservoir and distributor of molten steel in continuous casting, tundishes are used to remove inclusions in molten steel. The design of a tundish to improve the efficiency of inclusion removal requires a detailed knowledge of the flow behavior of the molten steel in the tundish. In this study, a 2-D mathematical model was developed based on a computational fluid dynamics technique, called SOLA-SURF, to analyze the flow behavior of molten steel in tundishes. Computed results describing the flow field, particle pathlines, particle residence times, and residence time distribution curves during steady state operation are presented. The effects of employing various combinations of flow control devices such as dams, weirs, and slotted dams on the flow field were also studied. The variations in flow field during the start and end of casting operation and during ladle transfer were also investigated. The information provided by the analysis has proven to be very useful to optimize tundish design and obtain cleaner continuously cast steel.
