Technological feasibility of combined process and installation of continuous casting and deformation to obtain high mechanical properties and fine-grained structure of steel sheets for weld pipes are considered. The problem of metal stress-strain state under solidified metal cobbing by the die walls of assembly mold is stated taking into account a force of the liquid phase pulling from the permanent crystallizer of installation. Parameters of cyclic deformation focus for thin slab sheets production, initial data for design and boundary conditions of the problem are given. A design scheme for determining stress-strain state of metal in circular deformation focus is presented. Results are obtained by solving the problem of continuum mechanics by finite element method: flat statement of contact problem of elastic-plasticity was used in conditions of large deformations and displacements. ANSYS software was used to solve the problem. The calculation results are presented in form of stress diagrams along the strip symmetry axis and on part of contact line of deformation focus with the die wall. Regularities of distribution of tangential stresses on contact surface of circular deformation focus are presented. Evaluation of solidified metal flow on the boundary with liquid phase during solidified metal cobbing by die walls is provided taking into account a force of liquid phase pulling from permanent crystallizer. The estimation of stress state scheme of metal in circular deformation focus during thin slab cobbing with a high degree of deformation is described in order to improve quality of steel sheets for weld pipes production. The main parameters of continuous casting and deformation plant for weld pipes steel sheets production are given. © 2017, National University of Science and Technology MISIS. All rights reserved.
