红柱石复合耐火砖及其制备方法和应用
摘要：
本发明提供一种红柱石复合耐火砖，包括主料和添加剂，所述主料包括下述质量百分数的原料：铝矾土熟料大颗粒5%～10%、红柱石大颗粒10%～20%、莫来石大颗粒14%～20%、红柱石小颗粒14%～30%、红柱石细粉15%～35%、高岭土微粉5%～10%、硅微粉2%～5%；所述添加剂的质量为所述主料质量的4.5%～5.5%。本发明还提供一种上述红柱石复合耐火砖的制备方法和应用。所述红柱石复合耐火砖成分搭配合理且具有良好的热震性、较好的热稳定性和较高的荷重软化温度，从而提高了应用所述红柱石复合耐火砖砌筑火道墙的碳素焙烧炉使用寿命。
摘要（英）：

The invention provides an andalusite composite refractory brick. The refractory brick contains a main material and additives, wherein the main material is prepared from the following raw materials in percentage by mass: 5-10 percent of bauxite clinker large particles, 10-20 percent of andalusite large particles, 14-20 percent of mullite large particles, 14-30 percent of andalusite small particles, 15-35 percent of andalusite fine powder, 5-10 percent of kaolin micropowder and 2-5 percent of silica micro-power; and the mass ofthe additives are 4.5-5.5 percent of the mass of the main material. The invention further provides a preparation method and application of the andalusite composite refractory brick. The andalusite composite refractory brick in reasonable in composition, and has excellent thermal shock property, good thermal stability and high refractoriness under load, so that the service life of a carbon calciner with an andalusite composite refractory brick laid flue wall can be prolonged.
