Magnesium aluminate spinel brick as well as preparation method and application thereof
The invention provides a magnesium aluminate spinel brick as well as a preparation method and application thereof, and relates to the technical field of refractory materials. The magnesium aluminate spinel brick provided by the invention is prepared from the following raw materials: 20 to 50 weight percent of magnesium lightweight porous aggregate, 15 to 30 weight percent of compact magnesium fine powder, 20 to 50 weight percent of compact magnesium aggregate, 10 to 30 weight percent of compact magnesium aluminate spinel aggregate, 1 to 3 weight percent of yellow dextrin and 1 to 3 weight percent of water. The magnesium aluminate spinel brick provided by the invention has the advantages of high porosity, low thermal conductivity, good wear resistance and good erosion resistance, and can be used for a transition zone working layer of a rotary cement kiln.
本发明提供了一种镁铝尖晶石砖及其制备方法和应用，涉及耐火材料技术领域。本发明提供的镁铝尖晶石砖，包括以下制备原料：镁质轻质多孔骨料20～50wt％，致密镁质细粉15～30wt％，致密镁质骨料20～50wt％，致密镁铝尖晶石骨料10～30wt％，黄糊精1～3wt％，水1～3wt％。本发明提供的镁铝尖晶石砖具有气孔率高、导热率低、耐磨性好、抗侵蚀性能好的优点，可用于水泥回转窑过渡带工作层。
