Dynamic Growth of Simple Oxide Inclusions

摘要

Steel researcher paid more attention on the description and control of size and distribution of inclusion inmolten steel. However, most of them focused on collision-growth among inclusions, a few of researcherconsidered inclusion's nucleation, Ostwald ripening[1,2]. Thus, we developed a mathematical model to studythe nucleation, Ostwald ripening and collision-growth (Brownian collision, Stokes collision and turbulentcollision) of alumina and zirconia inclusions in molten steel.
