The prospects of development of combined continuous casting and deformation processes in production of steel sheets for welded pipes are considered. Design of a pilot plant for combined continuous casting and deformation process for production of steel strips is described. Technological possibilities of installation of combined continuous casting and deformation process are described from the point of improving the quality of steel sheets for welded pipes as well as operating conditions of comb mold backup-walls of combined casting and deformation plant in production of them. Problem of simultaneous determination of stress-strain state of metal with focus on cyclic deformation and stress is posed, depending on compression force in walls of the comb molds of the installation. Initial data and boundary conditions for determination of stress-strain state of metal in focus of cyclic deformation are given using the ANSYS package. Diagrams of axial stresses are presented for preparation of sheets with section of 3×2250 mm made of 09G2S steel. Evaluation of the scheme of stressed state of metal with focus on cyclic deformation from the position of high-quality steel sheets production for welded pipes was carried out. Technique of determination of axial stresses is described depending on compression forces in steel sheets production for welded pipes in continuous casting and deformation plant. Design scheme and loading pattern of the backup-wall are given. Stress state of the backupwall is calculated in five sections, the results are presented for typical lines. The values and regularities of distribution of axial stresses in contact layer, in height and width of the backup-wall were determined depending on compression forces. Values of the greatest compressive and tensile stresses are given in relation to compression forces and their distribution in the backup-walls during production of steel sheets for welded pipes in combined continuous casting and deformation plant. © 2018, National University of Science and Technology MISIS.
