Study of cooling rate effect on back-diffusion during solidification of continuously cast steel billet

Original language description

Chemical heterogeneity of elements is predominant cause of imperfections and defects of cast and formed steel products. During crystallization and solidification of metals and alloys chemical non-homogeneities occur, i.e. chemical heterogeneities of individual elements, since the elements, both constitutive and tramp elements and admixtures, segregate. Parameter of back diffusion (the mass Fourier number) occurs in majority of the used micro-segregation models. The presented paper calculates parametersof back diffusion of determined elements (C, Si, Mn, P and S) in selected areas of cross-section of continuously cast steel billet. Calculations were made with use of our own experimental data, tabulated data and also outputs from heat model simulating temperature field of billet at solidification and cooling. On the basis of these results it is possible to formulate a hypothesis about influence of cooling rate on back diffusion of investigated elements at solidification of steel billet.
