Abstract The effects of flow control devices, casting speed of liquid steel, and inclusion size on inclusion removal in the continuous casting tundish were investigated using water modeling systems. Upward molten flow is investigated in this paper. Convection fluid flow, fluid flow pattern, and buoyancy force support the motion of non-metallic inclusions toward the tundish slag. To understand the fundamentals of the process, physical and mathematical modelings have been conducted in this work. Physical modelling is carried out with the utilization of a 1:4 scale model. Numerical modelling is carried out in line with the physical modeling to examine details of the flow pattern and rotational effect caused by the upward flow with the commercial CFD package environment, FLUENT. The mathematical model proposed is validated by comparing the predicted and measured results with VoF (Volume of Fluid) method.
