Physical modeling of Fluid flow Characteristics in a Delta Shaped, Four-Strand Continuous Casting Tundish with Different Flow Control Devices

Physical modeling using a 1:3 scale model was carried out to study the fluid flow characteristics in a delta shaped, four-strand continuous casting tundish with different types of flow control devices (FCD). The symmetric baffle with inclined holes (II shaped from top view) was not suitable in this study, while the U shaped baffle with inclined holes was suggested for the integrated fluid flow in tundish. The principles of U shaped baffle designs were proposed, and 18 types of FCD were evaluated by the residence time distribution (RID) curve and strand consistency. The RID curves of abnormal operations (with one strand closed) of the II shaped and U shaped baffles were also investigated.
