Abstract

노저에는 용탕탕류대를 가지고 노정상에는 선철, 파철, 주철 등의 지금(地金)투입구를 가지는 코크스 용해로의 용탕탕류대 바로 위의 용해대에 산소농도 25 내지 40%의 혼합 공기를 강제 송풍하는 송풍구를 다수개 설치하여, 용해대의 높이가 낮은 고온역과 환원역을 형성시키는 것을 특징으로 하는 수직형 고속 용해로.A tuyere that forcibly blows mixed air with an oxygen concentration of 25 to 40% into the melting zone just above the molten metal beds of the coke melting furnace, which has a molten metal flow basin in the furnace and a top inlet of pig iron, wrought iron, cast iron, etc. The vertical high-speed melting furnace characterized in that to form a plurality of, the high temperature zone and the reducing zone of the height of the melting zone is low.

Description
