选择特级煅烧焦宝石熟料（简称特级煅焦）微粉、α－Ａｌ２Ｏ３微粉为主要原料，加入适量添加剂，以木粉和聚苯乙烯塑料球为烧失物，采取可塑法成型、反应烧成、切磨加工等工艺手段，试制出了低成本、高性能的以莫来石为主晶相的直接舍成莫来石轻质砖。在淄博赛码公司１４５０℃梭式窑上作为内膛耐火材料使用，替代了进口产品，效果良好。 Select the special calcined coke clinker (abbreviated as super-calcined coke) micro powder and α-Al2O3 micro-powder as the main raw material, add appropriate additives, use wood powder and polystyrene plastic balls as burnt materials, adopt plastic molding, reaction firing, and cutting Grinding and other processing methods, trial production of a low-cost, high-performance direct mullite-based crystalline phase of the direct mullite light brick. It was used as a lining refractories on a 1450°C shuttle kiln at Zibo Racetrack and replaced the imported products.
