Abstract A mathematical model was developed to describe the inclusion dynamic growth process in the continuous casting mold. This model includes Eulerian method to predict turbulent flow and inclusion distribution in the continuous casting mold, and Lagrangian method to trace single inclusion in the inclusion concentration field and to study its collision and aggregation. Numerical results show that fluid flow is the key factor to affect inclusion’s distribution. In the continuous caster, the liquid steel and the inclusions have the upper and lower recirculation, and have “W” distribution at the exit. For the single inclusion, the seed inclusions can grasp the other inclusions continuously, thus, the bigger inclusions are dendritic with some tips and arms.
