Abstract

The attachment probability of inclusions on a bubble surface is investigated based on fundamental fluid flow simulations, incorporating the inclusion trajectory and sliding time of each individual inclusion along the bubble surface as a function of particle and bubble size. Then, the turbulent fluid flow in a typical continuous casting mold, trajectories of bubbles and their path length in the mold are calculated. The inclusion removal by bubble transport in the mold is calculated based on the obtained attachment probability of inclusion on bubble and the computed path length of the bubbles. The results are important to estimate the significance of different inclusion removal mechanisms. This work is part of a comprehensive effort to optimize steelmaking and casting operations to lower defects.
