Abstract

본 발명은 고로세 취입되는 미분탄을 제조하는 방법에 관한 것으로써, 연소성이 불량하여 고로미분탄 취입조업에 사용할 수 없는 석탄을 고휘발분탄과 혼합하여 고로취업조업에 사용이 가능한 혼합미분탄을 제조하고자 하는데, 그 목적이 있다.The present invention relates to a method for producing pulverized coal blast furnace blown coal, which is poor in combustibility and can not be used in blast furnace coal injection operation by mixing with high volatile coal to produce mixed pulverized coal that can be used in blast furnace employment operation , Its purpose is.

본 발명은 저휘발분탄과 고휘발분탄을 최종혼합분탄의 휘발분함량이 25%이상이 되도록 혼합하는 것을 특징으로 하는 고로취입용 혼합미분탄의 제조방법을 그 요지로 한다.The present invention has a summary of the method for producing mixed pulverized coal for blast furnace injection, characterized in that the low volatile coal and high volatile coal is mixed so that the volatile powder content of the final mixed coal is 25% or more.
