Numerical Modeling of the Fluid Flow in Continuous Casting
Numerical simulations were conducted to study the melt flow under the influence of control devices in a T-type two-strand bloom caster tundish via the open source Computational Fluid Dynamics software OpenFOAM. Three different cases were studied a bare tundish a tundish with two pairs of baffles and a tundish equipped with a turbulence inhibitor and a pair of baffles.

1. Introduction. Besides the basic functions of the tundish for continuous casting of steel modern tundishes plays also an important role of refining treatments to improve the quality and purity of cast steel. 1) Purity of steel is defined by the non-metallic inclusions in the steel product including their size quantity distribution chemical composition and mineralogy.

Slab molds receive liquid steel from the tundish through bifurcated submerged entry nozzles (SEN) using a slide valve as throughput control. Due to the off-centering position of the three plates rsquo orifices that conform to the valve to control the steel passage the flow inside the nozzle and mold is inherently biased toward the valve opening side. In the practical casting a biased flow
