Abstract: front page image
(EN)An apparatus for manufacturing molten iron and a method for manufacturing molten iron by using the same are provided. According to one embodiment of the present invention, the apparatus for manufacturing molten iron comprises: a melt gasifier furnace into which reduced iron and lumpy coal material are charged so as to manufacture molten iron; a reduction furnace connected to the melt gasifier furnace, manufacturing reduced iron from iron ore by using a reducing gas to be discharged from the melt gasifier furnace, and providing the reduced iron to the melt gasifier furnace; a blast furnace into which iron ore and coke are charged so as to manufacture molten iron; and a carbon dioxide removal device connected to the reduction furnace and the blast furnace, removing carbon dioxide from the exhaust gas of the reduction furnace, and blowing the same into the blast furnace.
(FR)L'invention concerne un appareil permettant de fabriquer du fer fondu et le procédé de fabrication de fer fondu l'utilisant. Selon un mode de réalisation de la présente invention, l'appareil permettant de fabriquer du fer fondu comprend : un four gazéificateur de fusion dans lequel du fer réduit et un matériau de charbon en morceaux sont chargés de manière à fabriquer du fer fondu ; un four de réduction relié au four gazéificateur de fusion, fabriquant du fer réduit à partir de minerai de fer à l'aide d'un gaz réducteur devant être évacué du four gazéificateur de fusion, et fournissant le fer réduit au four gazéificateur de fusion ; un haut fourneau dans lequel du minerai de fer et du coke sont chargés de manière à fabriquer du fer fondu ; et un dispositif d'élimination du dioxyde de carbone relié au four de réduction et au haut fourneau, éliminant le dioxyde de carbone du gaz d'échappement du four de réduction et soufflant ce dernier dans le haut fourneau.
(KO)용철 제조장치 및 이를 이용한 용철의 제조방법을 제공한다. 본 발명의 일 실시예에 의한 용철 제조 장치는 환원철 및 괴상 탄재가 장입되어 용철을 제조하는 용융가스화로, 용융가스화로에 연결되고, 용융가스화로에서 배출되는 환원가스를 이용하여 철광석을 환원철로 제조하고, 환원철을 용융가스화로에 제공하는 환원로, 철광석과 코크스가 장입되어 용철을 제조하는 고로 및 환원로 및 고로에 연결되고, 환원로의 배가스로부터 이산화탄소를 제거하고 고로에 취입하는 이산화탄소 제거기를 포함한다.
