Zusammenfassung:	The present invention relates to a method for producing a sintered ore and an apparatus for producing the same. The method for producing the sintered ore, to produce pre-reducing sintered ore by comprising the steps of: performing a sintering process using suction air of a ventilator (17), after inserting and igniting a sintering material (50) including iron ore fine into a sintering trailer (15); and converting by-product gas generated in the sintering process into reducing gas to supply the converted gas to the sintering material (50) which at this time is completing the sintering reaction in the sintering process. Therefore, the present invention can produce the pre-reducing sintered ore capable of improving reactivity and reducing carbon dioxide necessary for the reaction, so the use of a low grade material (iron ore fine) can be increased. 본 발명은 소결광 제조방법 및 소결광 제조장치에 관한 것으로, 분철광석을 포함하는 소결원료(50)를 소결대차(15)에 장입하고 점화한 후, 배풍기(17)의 흡입공기를 이용하여 소결공정을 수행하는 단계와, 상기 소결공정 중 소결반응 완료시점에 있는 소결원료(50)에 상기 소결공정에서 발생된 부생가스를 환원성가스로 변환하여 공급하는 단계를 포함하여 예비환원 소결광을 제조한다. 본 발명은 고로 반응성을 상승시키고 고로 반응에 필요한 이산화탄소를 저감시킬 수 있는 예비환원 소결광의 제조가 가능하므로 저품위 원료(분철광석)의 사용을 증가시킬 수 있는 이점이 있다.
