“Reducing Furnace And Apparatus For Manufacturing Molten Iron Comprising The Same”
Abstract: 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.
