Model Study of the Dynamics of Flow of Steel Melt in the Tundish.

Abstract

Thedynamics of steel melt flowing in the tundish is studied in a water model for a wide range of tundish design and operating parameters. Wider tundishes are found to produce short circuiting in comparison to the narrower tundishes. Empirical correlations are proposed to determine the residence times rel~vent to the tundish fluid flow system and their justification are discussed by using the momentum transfer mechanism in the turbulent flow. The utility of the correlations is discussed for the tundish design modifications.
