Summary:. This paper deals with the surface temperature of rolls during hot rolling of seamless steel tubes in stretch reducing mill in Zeleziarne Podbrezova. The main goal of our work was to measure the temperature of the rolls and compare it with the results coming from numerical simulation of hot rolling process. In general, the temperature of the tubes after stretch reducing should be higher than Ar3 by 30 ÷ 50 °C. The surface temperature of selected roll (so called "B-roll") was measured by means of a contact thermocouple-based method. Boundary conditions for numerical simulation of hot rolling process was set up according to the actual process conditions during rolling.
