Description

산화철 환원로에서의 직접 환원법 및 목탄 재순환 계통
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 회전로를 사용하여 해면철(海綿鐵)을 제조하는 종래의 방법을 예시한 직접 환원공정도.
제2도는 본 발명에 의한 것으로서 제1도에 예시된 직접 환원공정의 일부를 예시한 도면.

Claims (1)

  1. 환원제의 일부를 배출구에서 공급하고 나머지를 장입구에서 공급하며 탄화된 환원제를 로의 배출물에서 제거하여 재순환시킴에 있어서 재순환되는 탄화된 환원제를 배출구를 통해 로에 순환시키는 개선점을 특징으로 하는 회전로중에서 환원제 및 연료 공급원으로서 고체 탄소걸 환원제를 이용한 산화철 함유 물질의 환원방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
