Investigation of Influence of Cooling Rate on Back Diffusion at Solidification of Continuously Cast Steel Billet
Original language description
Parameter of back diffusion (the mass Fourier number) occurs in majority of the used micro-segregation models. It characterises diffusion of elements in solid phase in respect to the secondary dendrite arms spacing and to the local time of solidification. The presented paper calculates parameters of 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.
