摘要
PROBLEM TO BE SOLVED: To suppress a heat generation amount from a furnace wall in a vertical pyrolysis furnace for manufacturing ferrocoke, suppress deformation of a furnace body iron cover due to thermal strain and enhance the life of a refractory applied to the furnace wall.SOLUTION: The vertical pyrolysis furnace for manufacturing ferrocoke 1 has an iron cover 12 as an outermost shell and is constituted by applying two or more refractory layers inside of the iron cover, where the refractory layer is applied so that thermal resistance R of an iron cover side is larger than thermal resistance R of an inner side and the sum of thermal resistances R of each refractory layer, (R), is 1.2 mK/W or more, where the thermal resistances R of each refractory layer are defined by a ratio of thickness L and thermal conductivity k (R=L/k, unit:mK/W), where the thermal conductivity k (W/(m k)) and the thickness L of each refractory constituting the refractory layer is at room temperature.SELECTED DRAWING: Figure 1
