By a non-transformed arc plasma torch whose gas is nitrogen,scrap of high-carbon ferrochrome was heated and melted in a sealed furnace. When the liquid bath was at 1600℃,top blowing of oxygen began to decrease the bath's carbon without stopping plasma operation for its temperature addition and maintennace of at least 1750 ℃. The liquid bath was agitated by bottom-blowning nitrogen. In the experiments low carbon Fe-Cr have been obtained whose composition respectively was 0.45% carbon,50.75% chrome and 0.42% carbon, 70.25% chrome. Loss of chrome could be less than 5%.
