Abstract: 본 발명에 의한 탈린용선을 이용한 전로 용강의 제조방법은 일반용선 및 탈린용선의 취련 작업 중 발생된 슬래그를 탈린용선의 작업에 적합한 정량화된 10 내지 15톤의 슬래그로 맞추어 생석회 및 열간브리켓의 투입으로 잔류 슬래그를 고화시켜 탈린용선의 장입 중 폭발을 방지하고, 탈린용선의 취련 작업 중 잔류 슬래그에 함유된 유용한 성분인 CaO, FeO, MnO 및 SiO
2 을 활용하여 부원료의 투입량을 절감시킬 수 있으며 특히 품질 향상, 안정적인 용강의 생산성 증대 및 원가 절감의 효과 이외에도 탈린용선의 장입에 앞서 잔류 슬래그를 완전 배제하는 작업을 방지하여 슬래그 처리비용을 절감하고 환경오염을 방지하는 장점이 있다.
