For the sake of improving the calculation procedure for heat transfer in metallurgical unit dense beds a number of experiments has been carried out that allow adjustment of the heat transfer factor between the gas flow and the pellets in the course of heating. In the course of analysis, a permanent channeling flow was detected in the
pellet bed at Re = 100 – 1400. The heat transfer factor was calculated and the pellet temperature was determined in the course of heating within ± 11.4∘C.

Keywords: heat transfer in bed, pellet firing, dense bed, heat transfer factor, hydrodynamic resistance, gas flow
