The present invention relates to a reduction furnace including a charging device that is capable of preventing segregation and an apparatus for manufacturing molten iron including the same. The reduction furnace for reducing an iron-containing material used for manufacturing molten iron may include a charging hole where the iron-containing material is charged, a first guide plate sloped toward a first direction in the reduction furnace to guide the iron-containing material to the inside of the reduction furnace, and a second guide plate fixed and sloped toward a second direction intersecting the first direction in the reduction furnace to guide the iron-containing material dropped and guided by the first guide plate. A dropping direction of the iron-containing material dropped and guided by the first guide plate is changed when the iron-containing material is guided by the second guide plate.
L'invention se rapporte à un four de réduction qui comprend un dispositif de chargement capable d'empêcher la ségrégation et à un appareil destiné à la fabrication de fer en fusion dans lequel ledit four est intégré. Le four de réduction selon l'invention, qui est destiné à réduire un matériau contenant du fer lors de la fabrication de fer en fusion, peut comprendre : un trou de chargement dans lequel on introduit le matériau contenant du fer; une première plaque de guidage inclinée dans une première direction dans le four de réduction, qui guide le matériau contenant du fer vers l'intérieur du four de réduction; et une seconde plaque de guidage fixe, inclinée dans une seconde direction qui croise la première direction dans le four de réduction, qui guide le matériau contenant du fer dans sa chute en provenance de la première plaque de guidage. La seconde plaque de guidage change la direction de chute du matériau contenant du fer qui arrive en provenance de la première plaque de guidage.
