Low-thermal-conductivity spinel refractory homogeneous brick as well as preparation method and application thereof
The invention provides a low-thermal-conductivity spinel refractory homogeneous brick as well as a preparation method and application thereof, and belongs to the technical field of refractory materials. The low-thermal-conductivity spinel refractory homogeneous brick provided by the invention is prepared from the following raw materials: magnesia particles, magnesia fine powder, magnesium aluminate spinel particles, light hollow spheres, additive micro powder and a binding agent. The low-thermal-conductivity spinel fire-resistant homogeneous brick provided by the invention is uniform in material, the hidden danger that weak parts are easy to appear in a composite structure formed by different materials is avoided, and the problem that the composite brick is broken in the use process is avoided. Meanwhile, the low-thermal-conductivity spinel refractory homogeneous brick provided by the invention takes a periclase-spinel system as a matrix, is stable in high-temperature performance, is resistant to corrosion of alkali metals, volatile salts and the like, and is suitable for severe environments of rotary cement kilns or lime calcining kilns.
本发明提供了一种低导热尖晶石质耐火均质砖及其制备方法和应用，属于耐火材料技术领域。本发明提供的低导热尖晶石质耐火均质砖，制备原料包括镁砂颗粒、镁砂细粉、镁铝尖晶石颗粒、轻质空心球、添加剂微粉与结合剂。本发明提供的低导热尖晶石质耐火均质砖，其材质均一，不存在不同材质形成复合结构容易出现薄弱部位的隐患，使用过程中不会出现复合砖断裂的问题。同时，本发明提供的低导热尖晶石质耐火均质砖以方镁石‑尖晶石体系为基体，高温性能稳定，耐碱金属、挥发盐类等的侵蚀，适用于水泥回转窑或石灰煅烧窑的苛刻环境。
