Abstract
During continuous steel casting slag entrainment from the tundish into the mould has to be
avoided. Since slag entrainment most likely occurs at low tundish levels, this paper focuses on the
behaviour of the steel phase and the covering liquid slag during tundish draining. The process of
slag entrainment is modelled both numerically by a volume of fluid (VOF) approach and physically
by corresponding water-oil experiments. Thereby, the influence of a centric stopper and
additional inserts on the critical suction level is studied. With help of the numerical model these
results are subsequently extrapolated to real plant applications with steel and slag as liquid
phases. The numerical simulations have been proven to reasonably depict the onset of slag
entrainment during tundish draining and their results agree with corresponding experiments.
