Steel cleanliness still remains a major challenge for steel manufacturing due to the nature of high temperature procedure, the inevitable risk of atmosphere exposure, and other contamination in the casting process. Various improvements were introduced by the steel industry to pursue the objective of minimizing the as-cast defects. However, air entrainment continues to be investigated by researchers as one of the main sources of reoxidation. It is widely acknowledged that reoxidation of the liquid steel during pouring causes the formation of the nonmetallic inclusions. Both exposures due to diffusion of atmospheric oxygen to the stream as well as free surface folding are discussed. A review of previous work on mitigation techniques and conclusions on different factors in air entrainment will be presented. CFD modeling work of such phenomenon is discussed with focus on clean steel, process optimization, and advanced design.
