The use of boundary conditions, material data etc., in Computational Fluid Dynamics (CFD) for steelmaking processes faced is reviewed. The research state of fluid flow and its related phenomena on ladle refining processes and continuous casting mold processes is emphatically discussed. It should be recognized that the aim of computerized modeling in steelmaking processes is not to get exact numerical values or detailed descriptions of a given process but, instead, to get an insight into the processes. It is...
