The article presents the results of experimental studies of microclimate parameters (temperature, intensity of thermal radiation) at the area of an arc steelmaking furnace, on the basis of which the adequacy of mathematical models of heat transfer implemented in the ANSYS software package is confirmed. Mathematical models of heat transfer are represented by the discrete ordinate model (DO), which most accurately describes the transfer of radiative heat in space, and the Shear Stress Transport (SST) turbulence model. The use of these mathematical models will make it possible to pre-evaluate the thermal radiation situation at the projected or reconstructed objects, and also will allow you to choose effective means of thermal protection in advance.
