|Abstract:||In article the description of a new two-stage method of deformation continuously cast blooms at a stage of incomplete crystallization (patent UA №75537) is given, and also results of its complex research by methods of mathematical and physical modeling with reference to conditions of manufacture continuously cast blooms by section 335х400 mm are submitted. Results of computing experiment with use of the developed mathematical model realized with use of the finite - element method, have allowed to specify the mechanism of influence of chemical compound casting steel, parameters of process casting and external deformation influence on resulting physical-geometrical condition continuously cast blooms, and formed in metal stress - deformed condition. Rational parameters of deformations process which providing a minimum level of occurrence disruption of continuity is determined. Physical modeling of process with use of a new method (patent UA №77236) has allowed to identify results of numerical modeling, and also to develop methodology of research new technology on the basis of principles mechanics of deformation a solid body. By complex researches is shown, that in case realization of a new method achievable efficiency of penetration of deformation in the field of the metal, adjoining with front of crystallization, on 15…35 % are higher, than in case of deformation blooms by the smooth roll at the classical one-stage scheme of deformation.|
