Contribution to optimization of continuous casting of steel semiproducts
Original language description
This process can be described by the Fourier or the Fourier-Kirchhoff equations, which can not be solved exactly. An original three-dimensional (3D) numerical model (the first of the two) of a CCM temperature field had been assembled. The second originalnumerical model for dendritic segregation of elements assesses critical points of blanks from the viewpoint of their increased susceptibility to crack and fissure. In order to apply this model, it is necessary to analyze the heterogeneity of samples ofthe constituent elements (Mn, Si and others) and impurities (P, S and others) in characteristic places of the solidifying blank. The numerical model, based on measurement results obtained by an electron micro-probe, generates distribution curves showingthe dendritic segregation of the analyzed element, together with the distribution coefficients of the elements between the liquid and solid states. Both models will be used for optimization of concasting technology.
