The main loads acting on the backup-walls of the assembled mold of the combined continuous casting and deformation unit in production of steel sheets for welded pipes are described. The technique for determining the total stresses in backup-walls of the installation of the compression forces and the temperature load is given. The temperature boundary conditions for determining the temperature fields in the backup-walls of the assembled mold of the unit for steel sheets for welded pipes production are depicted. The dependence for determining the heat flux density of the deformation center hot metal influencing working surface of the backup-wall during workpiece drafting is considered, as well as the technique for determining values of effective heat transfer coefficients for backup-walls cooling by water. The procedure for determining temperature fields and thermoelastic stresses on backup-walls of the installation is described using the ANSYS package. The article considers the initial data for determining temperature fields and thermoelastic stresses in backup-walls of the assembled casting mold of the installation. The results of temperature fields and thermoelastic stresses calculation are achieved in five sections of the backup-wall and are provided for the typical lines. The nature of temperature distribution along the backup-wall thickness during cooling by water at idle and at contact with the workpiece during its compression is shown. For the calculated temperature fields, axial and equivalent stresses, that arise in the backup-walls without channels when the workpiece is drafted and cooled with water at idle, are determined. The values and regularities of distribution of axial and equivalent stresses along the thickness of the contact layer and along the height and thickness of the backup-walls during drafting of the workpiece and at idle are presented. The values and regularities of the distribution of total axial stresses along the thickness of the contact layer, the height and thickness of the backup-walls from the drafting forces and the temperature load are given. © 2018, National University of Science and Technology MISIS.
