Description 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 macro-heterogeneity. The derived model conceptions have confirmed the final condition of real continuous casting billets by using the advanced analyzing methods. Highlights · The quasi-equilibrium theory used to study the hardening processes of alloys has been expanded and improved.· The development of a numerical model for macrosegregation impurities in solidifying continuous casting billet is suggested.· The adequacy of the developed model is checked under the industrial conditions using comparison theoretical· calculations and practical data.· The results and developments that are obtained are discussed.
