焦炉耐火干粉密封料
摘要：
本发明涉及耐火材料的组份，尤其涉及一种可用于焦炉修补用耐火干粉密封料的组份。一种焦炉耐火干粉密封料，由以下组份组成(重量％)：(1)硅石，重量％为51～89％；(2)废硅砖粉，重量％为5～25％；(3)长石，重量％为5～20％；(4)硅微粉，重量％为1～5％；粉粒细度为≤0.074mm。本发明耐火干粉密封料不仅用于修补焦炉炉墙小裂缝、砖缝，延长焦炉使用寿命，而且可以检测炉体密闭性，防止焦炉煤气、废气及污染物等的泄漏，有利于环境保护，并且施工时操作简便，需要的设备简单。
摘要（英）：

The refractory powder as sealing material for coke furnace consists of silica 51-89 wt%, waste silica brick powder 5-25 wt%, feldspar 5-20 wt%, and fine silica powder of fineness not greater than 0.074 mm 1-5 wt%. The refractory powder is used in repairing cracks in coke furnace to prolong its service life, and may be used also in detecting the sealing performance of coke furnace to avoid the leakage of coal gas, waste gas and other pollutant to protect environment.
