Abstract
Understanding of the flow pattern of a molten steel through tundish is an essential precondition for estimating and avoiding negative effects on steel cleanliness. To study removal of inclusion in the tundish, experiments were carried out using a one third scale water model of the tundish with a dam and a weir. The flow patterns were determined by a flow visualization technique and by a theoretical analysis of the tundish system. The velocity field was predicted by solving the turbulent Navier-Stokes equations using the K-ε model for turbulent viscosity. There was a good agreement between the experimental results and the predictions. A plant test revealed significant improvements on slab quality such as reduction of surface defects of the cold-rolled sheets.
