Formula and firing process of high-temperature light mullite brick
The invention discloses a high-temperature light mullite brick formula and a firing process thereof, and relates to the technical field of refractory materials. The high-temperature-resistant high-strength concrete is prepared from the following components in parts by weight: 40 to 44 parts of aluminum oxide, 18 to 24 parts of kyanite, 10 to 15 parts of soft clay, 18 to 23 parts of high-temperature mullite, 25 to 35 parts of sawdust, 15 to 23 parts of burning-off type polyethylene balls and a reinforcing agent, the sawdust is used for forming a microcosmic air passage and reinforcing a pore passage; the sintering temperature of the mixture is 1200-1800 DEG C; the reinforcing agent is quartz stone powder; the invention aims to solve the problem of low strength of the existing lightweight heat-insulating refractory material prepared by an ignition loss method.
本发明公开了一种高温轻质莫来石砖配方及其烧制工艺，涉及耐火材料技术领域。本发明按重量份计，包括以下成分：氧化铝40~44份，蓝晶石18~24份，软质黏土10~15份，高温莫来石18~23份，锯木屑25~35份，烧除型聚乙烯球15‑23份以及加固剂；所述锯木屑用于形成微观气道以及对孔道进行加固；混合物烧结温度为1200℃~1800℃；所述加固剂为石英石粉末；以解决现有通过烧失法制备的轻质隔热耐火材料的强度较低的问题。
