REFRACTORY MORTAR, COKE OVEN CONSTRUCTION METHOD AND SELECTION METHOD OF REFRACTORY MORTAR
To provide a refractory mortar capable of ensuring sufficient sealing property regardless of the operating temperature of the site of use.SOLUTION: A refractory mortar to be used for joining shaped refractories together upon construction of a furnace wall using them, characterized in that the thickness MT of the refractory mortar at 100°C satisfies the following equation: MT=Mi(1+0.01αMT)≥Lj-0.005(αB1×LB1+αB2×LB2), wherein Mi is the thickness of the refractory mortar at the end of curing; αMT is coefficient of thermal expansion of the refractory mortar at 100°C; L j represents the joint thickness between Shaped Refractory 1 and Shaped Refractory 2 at room temperature when two adjacent shaped refractories are set to Shaped Refractory 1 and Shaped Refractory 2, respectively; αB1 is coefficient of thermal expansion of Shaped Refractory 1 at 100°C; LB1 is the room temperature length of Shaped Refractory 1; αB2 is the coefficient of thermal expansion of Shaped Refractory 2 at 100°C; and LB2 is the room temperature length of Shaped Refractory 2.SELECTED DRAWING: Figure 1
【課題】使用部位の稼働中の温度にかかわらず、十分なシール性を確保することのできる耐火性モルタルを提供する。【解決手段】定形耐火物を用いて炉壁を構築する際に定形耐火物同士の接合に使用する耐火性モルタルであって、１００℃における耐火性モルタルの厚みＭＴが次式を満たすことを特徴とする耐火性モルタル。ＭＴ＝Ｍｉ（１＋０．０１αＭＴ）≧Ｌｊ−０．００５（αＢ１×ＬＢ１＋αＢ２×ＬＢ２）ここでＭｉは養生終了時の耐火性モルタルの厚み、αＭＴは１００℃における耐火性モルタルの線熱膨張率、そして隣接する定形耐火物をそれぞれ定形耐火物１と定形耐火物２とし、Ｌｊは室温における定形耐火物１と定形耐火物２との間の目地厚み、αＢ１は定形耐火物１の１００℃における線熱膨張率、ＬＢ１は定形耐火物１の室温長さ、αＢ２は定形耐火物２の１００℃における線熱膨張率、ＬＢ２は定形耐火物２の室温長さである。【選択図】図１
