The thermal state of a hardening disc is considered. Such parameters were subjected to investigation as rotation speed, geometric dimensions of the disc, area of molten metal contact with the disc A mathematical model of the differential equation of the thermal state for a solid body was applied.. In calculations, the finite element method was used using the Comsol Multiphysics software product. Nonlinear relationships between the geometric dimensions and the temperature of the hardening disc heating were obtained. A study was made and the influence of technological parameters on the disc heating was determined. A technological mode was suggested, as a result of which a significant decrease in the mean temperature of the hardening disc is observed. Ref. 6, Fig. 6.
