Determination technological capabilities of new processes in deformation of continuously cast blooms of at the end of solidification

Abstract

In the work you can see description of new processes in deformation of continuously cast blooms at the end of solidification which were discovered at the department of Metal Forming of Donetsk National Technical University. The 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. Complex research shown, that new methods of deformation allow managing process of it penetration in to the metal, bounding with the solidification front. In addition, it’s possible to manage width of affixing reduction zone, dynamically.
