Zusammenfassung:	Provided are a method for agglomerating direct-reduced irons which efficiently removes gas existing between the direct-reduced irons; an apparatus for agglomerating the direct-reduced irons; and an apparatus for manufacturing molten irons comprising the same. The method for agglomerating the direct-reduced irons comprises: (i) a step of filling at least one gas selected from a group consisting of carbon monoxide and carbon dioxide in a space between the direct-reduced irons; and (ii) a step of converting carbon monoxide into carbon dioxide and carbon while agglomerating the direct-reduced irons. 분환원철 사이에 존재하는 가스를 효율적으로 제거할 수 있는 분환원철 괴성화 방법, 분환원철 괴성화 장치 및 이를 포함하는 용철제조장치를 제공한다. 분환원철 괴성화 방법은 i) 환원철들 사이의 공간에 일산화탄소 및 이산화탄소로 이루어진 군에서 선택된 하나 이상의 가스를 충전하는 단계, 및 ii) 환원철들을 괴성화하면서 일산화탄소가 이산화탄소와 탄소로 변환되는 단계를 포함한다.
