Beschreibung
Zusammenfassung:	The invention relates to the field of metallurgy, in particular û to a method for heating bars with a liquid core in the soaking pit and can be used for heating bars before the treatment with pressure at metallurgical plants. The method for heating bars with a liquid core in the soaking pit involves exposure of bars at reduced thermal power, increase of thermal power to maximal, rise of temperatures in the soaking pit to that specified at maximal thermal power; soaking bars at a stationary temperature in the soaking pit. At that, bars at the temperature of 840-920 DEGREE C are kept at the thermal power which is of 25-30 % of that maximal during 8-12 % of common time of heating, and increasing the thermal power to maximal is performed at a rate of 4-6 % per minute. The invention provides decreasing specific consumption of fuel for heating bars, diminishing metal losses of scale-forming and metal loss, decrease rejects in rolling steel ingots.
