Abstract

In order to make high-purity ferro-manganese from $Mn_3O_4$ dust, the application of aluminothermy process to the reduction of $Mn_3O_4$ dust was investigated in previous work. The result showed the fact that can be obtained high purity ferro-manganese which have over about 93% of manganese content and lower impurities such as C, P, S than those of KS D3712 specification. The addition of silicon powder instead of aluminum powder was investigated as reductant in the thermite reaction process of $Mn_3O_4$ dust in this work because its production cost is lower than that of aluminum powder. In case of addition of silicon powder only as reductant, the experimental result showed the unstable ignition and no thermite reaction of mixture, but in case of simultaneous addition of silicon and aluminum powders as reductant, showed the fact that can be obtained high purity ferro-manganese which have much low content of impurities such as C, P, S component.

이전의 연구에서는 $Mn_3O_4$ 분진으로부터 고순도 훼로망간를 얻기 위해, Al 테르밋법이 검토되었다. 그 결과는 Mn 함유율이 약 93% 이상이고, KS D3712 규격 이하의 낮은 C, P, S의 불순물을 함유한 고순도 페로망간을 얻을 수 있음 보여주었다. 본 연구에서는 제조 코스트가 Al 분말보다 저렴한 Si 분말이 $Mn_3O_4$ 분진의 테르밋 반응법의 환원제로 검토되었다. 그 결과 환원제로 Si 분말을 단독으로 첨가할 경우는 착화가 불안정하여 테르밋 반응이 일어나지 않았으나, 환원제로 Si 분말과 Al 분말을 동시에 첨가할 경우는 C, P, S의 불순물 함유율이 매우 낮은 고순도 페로망간을 얻을 수 있었다.
