Computational Modeling of Macroscopic Transportation in Continuous Castings

Macroscopic transportation in a continuous casting is modeled using the SIMPLER algorithm and the finite difference method. The simulation software Visual Cast has been developed to describe meniscus profile, fluid flow, solidification and centreline segregation based on the volume of fluid function and the mass, momentum, energy, and species conservation equations. It is found that the meniscus profile is coherently related to the position of circumfluence in the continuous casting mold. When the vortex above the flow jet from the nozzle is close to the meniscus, the level fluctuation becomes prominent. The centreline segregation is affected by the thermosolutal convection. The species concentration in the mush of the strand rises quickly and reaches a maximum at the end of the solidification.
