REPAIRING MATERIAL FOR FURNACE BOTTOM OF COKE OVEN
To provide a repairing material for a furnace bottom of a coke oven which is not apt to be peeled from a repaired part.SOLUTION: A repairing material of the present invention comprises: 70-95 mass% of refractory powder (pulverized powder of silica brick and/or baked silica); and 5-30 mass% of frit having a softening point of 350°C or higher and 700°C or lower. The refractory powder preferably comprises 55 mass% or more of tridymite. A particle diameter of the refractory powder is 5 mm or less. The main raw material comprises 10 mass% or more and 50 mass% or less of the refractory powder with a particle diameter of 75 μm or less. Further, it is preferable to add an admixture by 0.5-3 mass% of a sum of the refractory powder and the frit for stabilizing a dispersion of the composition. It is also preferable to add a clay by 5 mass% or less of the sum as needed.SELECTED DRAWING: None
【課題】被補修部分から剥離しにくいコークス炉の炉底補修材を提供する。【解決手段】耐火性粉末（珪石れんが粉および／または焼成珪石）を７０〜９５質量％、軟化点が３５０℃以上７００℃以下であるフリットを５〜３０質量％を含有する。また、前記耐火性粉末は、トリジマイトを５５質量％以上含有するのが好ましい。前記耐火性粉末の粒子径は５ｍｍ以下であり、粒子径が７５μm以下の耐火性粉末が前記主原料の１０質量％以上５０質量％以下である。更に、前記組成の分散を安定させるための混和材を上記耐火粉末とフリットの合量の０．５〜３質量％、また、必要に応じて粘土を前記合量の５質量％以下を添加することが好ましい。【選択図】なし
