Abstract
본 발명은 중저탄소 훼로망간의 제조방법에 관한 것으로, 좀 더 상세하게는 종래의 전로법을 개량하여 용탕침투 깊이/전체 용탕 깊이를 0.3-0.5로 유지하여 온도가 조절되도록 상취가스를 분사하면서 생석회일부 및 고탄소 훼로 망간 슬랙 소량을 산화기에서 투입하고, 산화기 말기에 생석회 나머지를 투입한 후, 튜이어의 위치를 전체용탕 높이의 0.2-0.3 범위로 유지하여 고탄소 훼로망간을 환원시켜 정련하므로써 종래의 중저탄소 훼로망간을 고수율로 회수할 수 있는 중저탄소 훼로망간의 제조방법에 관한 것이다.The present invention relates to a method for producing low and low carbon ferro-manganese, and more specifically, by improving the conventional converter method to maintain the molten metal penetration depth / total melt depth to 0.3-0.5 while spraying the fresh gas to control the temperature of quicklime lime After a small amount of manganese slack is added to the oxidizer, and the remainder of quicklime is added to the end of the oxidizer, the position of the tuber is maintained within the range of 0.2-0.3 of the total melt height to reduce the high carbon ferro-manganese. Therefore, the present invention relates to a method for producing a low to low carbon ferro manganese, which can recover a conventional low to low carbon ferro manganese.
