Description

선철의 탈탄을 위한 산소 주입랜스용 노즐과 크롬함유 선철의 탈탄을 위한 노즐의 사용
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 공지의 초음속 산소분사용 노즐의 개략도.
제2도는 잘려진 원뿔형 노즐의 분기부분의 정점에서의 각에 따른 분사의 추력의 변화도.
제3도는 본 발명에 따른 초음속 산소분사용 노즐의 개략도.
제4도는 노즐의 잘려진 원뿔형 분기부분의 정점각에 따른 크롬의 수득률의 변화도.

Claims (5)

  1. 정점각이 60-70°사이인 잘려진 원추분기와로 구성됨을 특징으로 하는 초음속 산소분사에 의한 용융선철의 탈탄을 위한 노즐.
  2. 잘려진 원추분기부가 62-66°사이의 정점각, 바람직하게는 65°의 각을 가짐을 특징으로 하는 청구범위 제1항에 따르는 노즐.
  3. 잘려진 원추부를 지나 노즐의 분기부가 동축과 내측으로 향한 요면을 가지는 발생곡부에 관한 회전표면을 가짐을 특징으로 하는 청구범위 제1항이나 제2항에 따르는 노즐.
  4. 크롬함유 선철의 탈탄을 위한 청구범위 제1항에서 3항까지의 어느 한항에 따르는 노즐의 사용.
