Abstract. Mode of heating of rails the RP65 for tempering in the rail-shop department of JSC «EVRAZ-NTMK» is considered. Two experiments were performed with a change of heating mode of billet. Temperature was uneven on rails, because speed of heating was increasing. A constructive solution is proposed. Frequency converters installing for each zone of the furnace, will provide different heating rates in the packages with rails, with an increase in the intensity of heating and ensuring the uniformity of the temperatures obtained at different points, thereby increasing productivity of the furnace.
Keywords: through furnace, mode of heating, rail, rollers, zone of heating, frequency converter, thermocouple, mode of speeds.
