Application of computational fluid dynamics to steelmaking processes

Today, the numerical simulation of fluid dynamic phenomena (CFD) in steelmaking applications is state of the art. The latest simulation results for the BOF and AOD as well as the thin strip casting process are described. The basic influence of the process parameters, e.g. blowing and stirring rate, vessel dimension, location of top lance, number and arrangement of porous plugs, on the converter melt flow and mixing time is simulated. In the case of thin strip casting, the free melt flow on the moving belt is influenced by an induced electromagnetic field. The respective MHD (magneto-hydrodynamic) is presented.
