Numerical Simulation of Macrosegregation Impurities in the Solidifying Continuous Casting Steel Billet

In this study, new theoretical conceptions have been developed about an impurity segregation mechanism at the time of alloy solidification considering present microvolumes with different chemical compositions during alloy solidification. It has been concluded that this conception allows to establish and optimize technologic parameters that influence the production of the main types of macroheterogeneity. The derived model conceptions have confirmed the final condition of real continuous casting billets by using the advanced analyzing methods.
