Title

Fluid Flow and Inclusion Motion in Horizontal Continuous Casting Tundishes

Abstract

The configuration of the tundish for a two-strand horizontal continuous caster were designed and optimized through water modeling, mathematical modeling and industrial trials. Three designs of the tundish were studied: the original tundish without any flow control devices, the tundish with a turbulence inhibitor at the bottom, and the tundish with an inlet launder and a tilted dam. In the water modeling, the residence time, the fraction of the dead zone, and fluid flow pattern were investigated. In the mathematical modeling, fluid flow, heat transfer and inclusion motion and removal were calculated. In the industrial trials, the total oxygen, nitrogen, and inclusions in the steel samples from the tundish and the billets were investigated. The results indicated that the tundish with an inlet launder and a tilted dam was the best of the three designs.
