Abstract
Способ электрошлакового переплава в водоохлаждаемом кристаллизаторе, включающий одновременное пропускание через расходуемый электрод рабочего тока и импульсного разрядного тока с напряжением 20 - 50 кВ, отличающийся тем, что, с целью повышения эффективности обработки и улучшения качества переплавляемого металла, обработку ведут попеременно чередующимися круто возрастающими-полого спадающими и полого возрастающими-круто спадающими импульсами разрядного тока с максимальной амплитудой тока в импульсе 5 - 50 кА и с частотой импульсов 0,5 - 500 Гц при отношении времени крутого возрастания (убывания) импульса к общему времени разряда его 1/20 - 1/10.The method of electroslag remelting in a water-cooled mold, including the simultaneous transmission of a working current and a pulsed discharge current with a voltage of 20–50 kV through a consumable electrode, characterized in that, in order to increase processing efficiency and improve the quality of the metal being smelted, the treatment is alternated steadily increasing-hollow falling and hollow rising-steeply falling discharge current pulses with a maximum current amplitude in a pulse of 5-50 kA and a pulse frequency of 0.5 to 500 Hz with respect to the time of steep increase (decrease) of the pulse to the total discharge time of its 1/20 - 1/10.
