Sažetak
An analysis of the process of heating a graphitized hollow electrode (GHE) during steel processing at the “ladle-furnace” unit was carried out. Coefficients of the heat transfer by convection have been calculated for the inner and outer GHE surface: 1, 60 and 1, 80, and 5–17 W/(m2∙°C), respectively. Values of the electrode temperature gradient in the high-temperature zone were obtained, which, for the first heating period, reached 8, 286 °C/m, for the third ‒ to 6, 571 °C/m. It was established that during the cooling periods of the electrode, the temperature gradient is significantly reduced and amounts to the inner surface of 379 °C/m ; to the outer surface ‒ 3, 613 °C/m.
