Removal of Inclusion with Different Morphology in a Continuous Billet Caster

Numerical simulation is applied to study the three dimensional flow field and the inclusions'trajectories in the continuous billet caster in order to have a deep insight into the effect of particle shape on the inclusion removal rate.The numerical results show that for the inclusions with the same shape,the inclusion removal rate increases with the increase of inclusion size.For the inclusion with the same size,the removal rate of the inclusion increases with the decrease of particle shape factor.For the inclusion smaller than 5 micros,the effect of the size and morphology of inclusions on the inclusion movement is very weak.
