Description

공기분사 파이프 있는 회전로에 의한 철광석 직접환원법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 종래의 해면철 생산용 직접 환원 공장의 공정도.
제2도는 본 발명에 의한 것으로서 제1도에 예시된 공장에서 사용되는 형식의 환원로의 개략도.

Claims (1)

  1. 공급구쪽으로 예열대가 있고 배출구쪽으로 환원대가 있는 회전로의 길이를 따라 축방향으로 산소를함유하는 가스를 분사할 때 공급구쪽의 예열대의 최소한 1차부분으로 가스를 분사하고 나머지 가스를 배출구 방향으로로 속에 분사하므로서 고체탄소질 환원제와 상소를 함유하는 가스를 이용하여 산화철을 함유한물질의 직접 환원을 위해 회전로 속으로 공기를 도입하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
