In the continuous casting the molten metal form ladle is not directly poured in the mold, it is poured in to tundish for assuring continuous flow and refining purposes. Tundish not only assures the continuous flow but also performs inclusion removal process. Design parameters of tundish comprises critical dominance over the quality of metal production. In this review, the parameters affecting the tundish over the metal production quality are reviewed. The parameters affecting the tundish are the fluid flow, flow modifiers utilized, residence time distribution (RTD), temperature distribution in tundish, inclusion removal efficiency, etc. Fluid flow modifiers utilized in optimizing the fluid flow are weir, dam, baffle and turbulence inhibiter (impact pad). All the parameters which affects the metal production through tundish are estimated and presented. It is concluded that the shape and size of tundish, inclusion removal efficiency, residence time distribution (RTD), types and locations of flow modifiers, the ladle to tundish and tundish to mold flowrate, the number of inlet and outlet strands and shrouds are the parameters which affects the quality of metal production through tundish.
