Abstract

본 발명은 제철소에서 발생되는 분말철의 고로취입방법에 관한 것으로서, 그 목적은, 분말철을 고로의 풍구에 취입할 때 분말철을 용융환원시킬 수 있는 탄화수소 매체로 조정제된 폐윤활유를 사용하므로서, 분말철을 분말 상태 그대로 취입할 수 있는 효과적인 고로취입방법을 제공하고자 하는데 있다.The present invention relates to a blast furnace blowing method of powder iron generated in steel mills, the object of which is to use waste lubricating oil adjusted to a hydrocarbon medium that can melt reduced powder iron when blowing powder iron into the blast furnace blast furnace, An object of the present invention is to provide an effective blast furnace blowing method which can blow powder iron as it is.

상기 목적을 달성하기 위한 본 발명은 조정제된 폐윤활유에 50중량% 이하의 철분말을 혼합하여 슬러리를 제조한 다음, 이 슬러리 연료를 고로 풍구내로 분사하여 구성되는 분말철의 고로 취입방법에 관한 것을 그 요지로 한다.The present invention for achieving the above object is to prepare a slurry by mixing up to 50% by weight of the iron powder to the adjusted waste lubricating oil, and then relates to a method for blowing the powder iron blast furnace composed of spraying the slurry fuel into the blast furnace tuyere That's the point.
