ABSTRAKT

Turbulent structures are important in influencing inclusion transport in continuous casting of steel. The turbulent velocity field and inclusion transport are studied in a full-scale water model using large eddy simulations. The computed fluid velocities are compared with measurements. Chaotic vortex structures were computed in the upper roll region as expected. The computed inclusion trajectories were processed to determine the inclusion removal rate to the top surface. The results agree reasonably with measurements from the water model. The removal of particle inclusions to the top surface is found to be independent of the particle initial positions at which they enter the mold.
