| Abstract Scope |
Twin-slab continuous casting differs from conventional slab casting because slab-width adjustment causes the submerged entry nozzle (SEN) to become off-centered, creating an inherently asymmetric mold geometry. While its influence on mold flow has received limited attention, its effect on argon bubble transport remains largely unknown. In this study, a three-dimensional Eulerian–Lagrangian model was developed to investigate argon bubble transport, escape, and capture under different slab widths. The results show that asymmetric flow produces distinct bubble transport behaviors on the two sides of the mold. On the narrower side, the shorter jet path increases bubble capture by the solidifying shell, whereas on the wider side, stronger downward recirculation transports bubbles deeper into the mold. Bubble escape through the meniscus also varies with slab width. These results demonstrate that twin-slab geometric asymmetry significantly alters bubble transport and should be considered in process optimization to reduce bubble-related defects. |
