Abstract
The mathematical model of the thermal state of the sheet metal has been developed, taking into account radiation heat exchange and convection between the metal surface and the environment, the impact of descaling, heat transfer at the contact of metal with rollers, and also the heating of the metal due to plastic deformation. The model uses the results of mechanical tests obtained on the installation of the Gleeble 3800 under plane strain compression. Simulation of the rolling process is performed in the software complex «Deform 3D». The results of mathematical modeling adequately reflect the study of the thermal state of the metal produced in a sheet rolling shop. The model can be used to study the thermal state of the metal in the hot rolling production of high-quality steel grade.
