Abstract

본 발명은 용선예비처리 설비에서 용융물 운반용기인 토페토 래들 카(Torpedo Ladle Car)에 수선된 용선의 표면부분이 응고되거나 대형지금(地金)이 형성되어 있을 경우 간단하게 지금을 용해시킬 수 있는 방법과 장치에 관한 것으로, 보다 상세히 설명하면 용선표면의 지금(地金)형성부분에 착호제인 코크스와 목재를 사전투입한 후, O2를 취입(Blowing)시켜 지금을 용해시킨후 부원료 취입랜스가 용선내부로 침적되어 용선예비처리작업을 가능하게 함으로서 용선수금 원활하에 따른 생산성 향상과 전후 공정의 부하를 경감하여 제강작업에 만전을 기할 수 있도록 한 용선운반용기 내부에 고착된 용선 지금(地金)의 용해방법과 그 용해장치를 제공한다.The present invention is a method that can simply dissolve the present when the surface portion of the molten iron is solidified in the molten iron container Torpedo Ladle Car solidified or formed in the molten iron preliminary treatment facilities And more specifically, the coke and wood, which are the protective agents, are pre-injected into the now forming part of the surface of the molten iron and then blown with O 2 to dissolve the present, and then the raw material blowing lance is molten. The chartered vessels fixed inside the chartered vessel are designed to allow for the preliminary treatment of the chartered vessels, thereby improving productivity due to smooth payouts and reducing the load on the post-war process. Provide a dissolution method and dissolution apparatus.
