Modeling on the Motion and Entrapment of Non-metallic Inclusions in a Steel Continuous Casting Billet Strand

摘要

The current work was to predict the particle entrapment into the full length of a billet caster strand using mathematical modeling.The modelconsideredthe effect of turbulent flow,heat transfer,solidification,and the motion of inclusions.Inclusions will be entrapped once they move to the location with a liquid fraction of 0.6.The calculated inclusion distribution in the billet agreed with the industrial measurement.A peak of inclusions close to the center of the billet was observed both by the calculation results and the industrial measurement.
