Abstract
Description
3: 용해로 4: 천정부
첨부된 도 2는 본 발명의 적용되는 파이넥스 공정에 따른 제선 공법을 설명하기 위한 개략도이고, 도 3은 도 2의 구성요소인 유동층 환원로를 나타낸 확대도로써, 상기 파이넥스 공정은 분철광석을 여러단계의 유동층 환원로(1)에서 단계적으로 환원시켜 용해로(3)에 8∼50㎜의 성형탄과 함께 장입하여 용선을 만드는 것으로, 약 8mm의 분철광석이 여러단계로 나누어진 유동층 환원로(1)를 지나 환원된 철광석으로 변화되고, 이것을 성형하여 펠렛 형태(HCI;Hot Compact Iron)로 용해로(3)에 장입하여 원하는 쇳물을 경제적으로 생산하려는 새로운 제선 공법이다.
