Abstract
Proper tundish design plays a vital role in improving the metallurgical quality of the final product in the continuous casting process of steel. Key design objectives include increasing the residence time (RTD) of molten steel, reducing dead volume, and preventing the formation of direct flow paths. These factors promote the effective separation of impurities through argon gas injection and their flotation to the slag layer, ultimately enhancing product quality. In this study, the effect of implementing a longitudinal flow-control dam on the flow pattern inside a six-strand tundish is numerically investigated. Computational Fluid Dynamics (CFD) simulations are used to compare flow behavior with and without the dam. The results indicated that the dam significantly reduces dead volume, improves outlet flow uniformity, and enhances residence time. The model was validated using data from an industrial billet casting unit, confirming the practical feasibility of the approach.
