Abstract

본 발명은 고로원료로 사용되고 있는 소결광을 제조하는 방법에 관한 것으로서, 무연탄을 소결원료층의 상부로, 코크스를 하부로 편석되게하여 소결광을 제조함에 있어 무연탄의 입도관리에 의하여 소결원료의 장입시 자동적으로 무연탄을 상부로, 코크스를 하부로 편석되게 하므로서 별도의 설비없이 회수율 및 생산성이 우수한 철광석 소결광을 제조하고자 하는데, 그 목적이 있다.The present invention relates to a method for manufacturing sintered ore which is used as blast furnace raw material, and to produce sintered ore by segregating anthracite to the top of the sintered raw material layer and coke to the bottom. In order to produce an iron ore sintered ore excellent recovery and productivity without additional equipment by allowing the anthracite coal to be segregated to the top, and the coke to the lower, there is a purpose.

본 발명은 열원으로서 코크스를 사용하여 소결원료를 소결하는 철광석 제조방법에 있어서, 코크스일부를 무연탄으로 치환하여 무연탄을 소결원료층의 상부로, 코크스를 하부로 편석하게하고; 상기 무연탄의 양이 코크스에 대하여 10-30 wt% 이고; 그리고 상기 무연탄의 입도가 0.5~2.0mm인 철광석 소결광의 제조방법을 그 요지로 한다.The present invention relates to an iron ore manufacturing method for sintering a sintered raw material using coke as a heat source, comprising: replacing a coke portion with anthracite to make anthracite coal upper and sintered coke lower; The amount of anthracite is 10-30 wt% with respect to coke; And the summary is made into the iron ore sintered ore manufacturing method of the particle size of the anthracite coal is the main point.
