Lime rotary kiln heat preservation layer heat insulation castable as well as preparation method and application thereof
The invention discloses a lime rotary kiln heat preservation layer heat insulation castable as well as a preparation method and application thereof. The invention relates to a heat-insulating castable for a lime rotary kiln heat-insulating layer. The heat-insulating castable comprises the following raw materials in parts by mass: 70-75 parts of premixed fine powder; 100 parts of cordierite particles; 9-12 parts of a magnesium dihydrogen phosphate solution; wherein the premixed fine powder comprises calcium akermanite fine powder, enstatite fine powder, magnesium rhodonite fine powder and dodecacalcium heptaaluminate fine powder. The process for preparing the lime rotary kiln insulating layer from the castable is simple, high-temperature firing or medium-temperature heat treatment is not needed, and the preparation cost is low; the prepared heat insulation castable for the lime rotary kiln heat preservation layer can be rapidly sintered under the condition that the temperature does not exceed 1000 DEG C, good bonding strength is formed, and energy is saved; the castable is small in heat conductivity coefficient and low in thermal expansion coefficient; explosion-proof fibers do not need to be added into the castable, and the bursting resistance is good; the castable is good in fluidity, uniform in dispersion and uniform in heat transfer at high temperature.
本发明公开了一种石灰回转窑保温层隔热浇注料及其制备方法和应用。本发明的一种石灰回转窑保温层隔热浇注料，包括如下质量份数的原料：预混细粉料70～75份；堇青石颗粒100份；磷酸二氢镁溶液9～12份；其中，预混细粉料包括钙镁黄长石细粉、顽火辉石细粉、镁蔷薇辉石细粉和七铝酸十二钙细粉。该浇注料制备石灰回转窑保温层工艺简单，无需高温烧成或中温热处理，制备成本低；所制备的石灰回转窑保温层隔热浇注料能够在不超过1000℃条件下快速烧结并形成良好的结合强度，节约能源；浇注料导热系数小，热膨胀系数低；浇注料无需添加防爆纤维，抗爆裂性能好；浇注料流动性好，分散均匀，高温下传热均匀。
