Abstract
본 발명은 제철원료로서 각종 분철광석을 배합하여 괴성화하는 소결광의 제조에 있어서 마그카본 폐연와를 활용하는 방법에 관한 것이다. 본 발명의 마그카본(MgO-C) 폐연와를 활용한 철광석 소결광 제조방법은 철광석 소결광의 제조에 있어서, 제강 공정의 전로 내장용 등으로 사용하 후 폐기되는 마그카본 폐연화를 파쇄하여 입도를 3㎜이하로 하되 그중 2㎜이하의 중량비가 70%이상이 되도록 조절한 후 철광석, 석회석, 규석 등 일반 소결원료 및 연로와 함께 배합하여 소결하는 것을 특징으로 한다.The present invention relates to a method for utilizing magcarbon waste smoke in the manufacture of sintered ore which mixes and hardens various iron ore as raw materials for steelmaking. Iron ore sintered ore manufacturing method using the mag carbon (MgO-C) waste lead of the present invention in the manufacture of iron ore sintered ore, crushed mag carbon waste softened to be discarded after use for the converter interior of the steelmaking process, etc. It is characterized by sintering to less than ㎜ but adjusted to a weight ratio of less than 2㎜ of more than 70% and mixed with general sintering raw materials such as iron ore, limestone, quartzite and fuel.
