Mathematical Analysis of Inclusion Removal from Liquid

The mechanism of inclusion removal from liquid steel by gas bubbling and bubble attachment in the tundish is complex due to the great nuer of variables involved and it is even more difficult to study because of the turbulent flow conditions The main objective of this work is to analyze and improve the understanding of the alumina inclusion removal rate by bubble attachment and by
