Abstract

본 발명은 고로용 원료인 소결광을 제조하는 방법에 관한 것으로써, 고료용 원료인 소결광 제조방법에서 원료의 사전처리 공정중 조립에 사용되는 생석회 대용으로 분 소성 백운석을 사용하고, 이를 소결하는 경우에 발생되는 소결광의 강도저하를 방지하기 위한 수단으로 미분 철광석 입자, 원료처리 집진 더스트 및 제강공정 발생 슬러그를 미분화하여 첨가하되 이들을 조립 공정의 부착입자로 하여 소결시융액 형성용 코팅제로 사용함으로서 소결광의 강도 저하를 방지할 수 있는 소결광 제조방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method for producing sintered ore, which is a raw material for blast furnace, and in the case of sintered ore, which is a raw material for raw materials, using pulverized dolomite as a substitute for quicklime used for granulation during pretreatment of raw materials. As a means to prevent the reduction of the strength of the sintered ore generated, finely divided fine iron ore particles, dust treatment raw material dust, and slugs generated in the steelmaking process are added to the micronized particles. An object of the present invention is to provide a method of manufacturing a sintered ore capable of preventing a decrease.

본 발명은 소결광을 제조하는 방법에 있어서, 소결배합원료에, 소결배합원료 중량에 대하여 바인더인 분소성 백운석 : 1-2중량%, 및 전로슬래그, 미분철광석, 및 소결원료 처리공장에서 원료처리시 비산되는 미분을 포집한 미분더스트로 이어진 용액 형성용 코팅제 그룹으로부터 선택된 1종 또는 2종 이상의 용액형성용 코팅제 : 중량 5% 이하를 첨가하여 조립한 다음, 소결하여 소결광을 제조하는 방법을 그 요지로 한다.The present invention relates to a method for producing a sintered ore, when the raw material is processed in a sintered blend raw material, powdered dolomite as a binder with respect to the weight of the sintered blend raw material: 1-2 wt%, and converter slag, fine iron ore, and sintered raw material processing plant One or two or more solution-forming coatings selected from the group of solution-forming coatings formed by collecting fine powders scattered to the ground: 5% or less by weight is added, granulated, and then sintered to produce a sintered ore. do.
