摘要

Theoretical fundamentals on the interaction between bubbles and inclusions in the molten steel are reviewed. The mechanism of bubble–inclusion interaction, bubble size and rising velocity, liquid film formation and rupture between bubble and inclusion, collision time, film drainage time, and sliding time were discussed and calculated.
