Non-metallic inclusions represent one of the most prevalent and severe defects present in steel castings. The most common forms of inclusions are those resulting from reoxidation of the steel during pouring. A computational model is developed to predict the formation of reoxidation inclusions during pouring of steel castings, the subsequent advection and buoyant movement of the inclusions, and their final size and location in the solidified casting. Air entrainment during filling is modeled using a novel approach that takes into account the turbulent motion of the melt at the free surfaces. Experiments are conducted to better understand the physical mechanisms leading to reoxidation during mold filling. The predictions compare favorably to the experimental data.
