PROBLEM TO BE SOLVED: To provide a vertical carbonization furnace for manufacturing a ferro-coke that uniformly heats a material, has a simple structure, and reduces a construction cost and an operation cost.SOLUTION: A vertical carbonization furnace for manufacturing a ferro-coke of the present invention that carbonizes a molding of a carbon-containing material and an iron-containing material comprises: a carbonization furnace body 2 having a cross-section along a plane vertical to a longer direction of the furnace that has a rectangular shape; and a tuyeres 5 installed on a circumferential side surface of the carbonization furnace body for blowing gas into the carbonization furnace body. Two tuyeres or more are installed on both opposed long sides of the circumferential side surface, respectively. A ratio of an interval b between the adjacent tuyeres on the long sides to an interval a between the tuyeres on short sides of a circumferential side surface, a/b, is from 0.9 to 1.1.SELECTED DRAWING: Figure 2 【課題】原料を均一に加熱することが可能であり、かつ構造が簡便で、低コストで建設・操業することが可能なフェロコークス製造用竪型乾留炉の提供。【解決手段】炭素含有物質と鉄含有物質との成型物を乾留してフェロコークスを製造するフェロコークス製造用竪型乾留炉であって、長手方向に対して垂直な平面における断面の形状が長方形である乾留炉本体２、および乾留炉本体の周側面に設けられた、乾留炉本体内へガスを吹き込むための羽口５を備え、羽口は、周側面の対向する長辺のそれぞれに、２つ以上ずつ設けられており、長辺上における隣接する羽口の間隔ｂに対する、周側面の短辺方向における羽口間の距離ａの比ａ／ｂが０．９〜１．１である、フェロコークス製造用竪型乾留炉。【選択図】図２
