Abstract

본 발명은 소결조업시 발생되는 전기집진기의 분진과 백운석을 소성하기 전 수세하는 과정에서 발생되는 백운석 슬러지를 적절히 배합한 후, 소성하여 소결공정에 필요한 조재제로 활용하므로서, 품질특성이 우수한 소결광을 제조하는 방법을 제공하고자 하는데, 그 목적이 있다.The present invention mixes the dust of the electrostatic precipitator generated during the sintering operation and the dolomite sludge generated during the washing process before firing the dolomite, and then sintered to produce a sintered ore excellent in quality characteristics by utilizing as a preparation agent for the sintering process To provide a way to do that, the purpose is.

상기 목적을 달성하기 위한 본 발명은 제철용 고로원료인 소결광을 제조하는 방법에 있어서, 소결조업시 배출되는 전기집진기의 분진과 백운석을 소성하기 전 수세히 발생되는 백운석 슬러지를 0.5∼2의 중량비로 배합한 후, 1200∼1250℃의 온도에서 소성하여 소결조재제를 만들고, 상기 소결조재제를 소결부원료의 중량에 대하여 10∼25%의 범위로 소결광 배합원료에 첨가한 다음 통상의 방법으로 소결하는 소결광의 제조방법에 관한 것을 그 요지로 한다.In order to achieve the above object, the present invention provides a method for producing sintered ore, which is a blast furnace raw material for steelmaking, in which the dolomite sludge generated before washing the dust of the electrostatic precipitator discharged during the sintering operation and the dolomite at a weight ratio of 0.5-2. After blending, the mixture is calcined at a temperature of 1200 to 1250 ° C. to form a sintering aid, and the sintering aid is added to the sintered ore blending material in a range of 10 to 25% by weight of the sintering auxiliary raw material and then sintered by a conventional method. The summary relates to a method for producing a sintered ore.
