Inclusion Density in Tundish Zones Using Fluid Flow Simulations

In the continuous casting of steels, tundish flow control devices may create uniform streamline zones and/or turbulent flow ones. Depending on the condition, inclusions may be removed throughout an agglomeration process by Stokes, turbulent or Brownian collisions or adhesion to the solid surfaces. In this work, a finite differentiation computer was employed to solve numerically the flow conditions in a tundish used in a steelmaking plant. K-ε two-equation model and three-dimensional fluid flow was applied. Simulations have shown the zones with strong stirring energy and others with uniform streamline. The change rate of inclusion number density was evaluated and compared with literature results.
