Refractory composite material as well as preparation method and application thereof
The refractory composite material comprises bauxite tailings with the particle size smaller than or equal to 50 mm and high-aluminum slag, the high-aluminum slag is dust collection powder generated in refractory material production and/or dust removal powder generated in brown aluminum oxide production, the content of Al2O3 in the dust collection powder and/or the dust removal powder is 50-70 wt%, and the mass ratio of the bauxite tailings to the high-aluminum slag is (7-9): (1-3). The raw materials are low in cost and can be directly used as production raw materials of refractory materials, grinding materials and brown aluminum oxide, and the production cost of products can be greatly reduced.
一种耐火复合材料，包括铝矾土尾矿，粒度≤50mm，以及高铝矿渣，所述高铝矿渣为耐火材料生产产生的收尘粉和/或棕刚玉生产产生的除尘粉，收尘粉和/或除尘粉中Al2O3含量为50‑70wt％，铝矾土尾矿和高铝矿渣的质量比为7‑9：1‑3。本发明原料成本低，可直接作为耐火材料、研磨材料、棕刚玉的生产原料，可极大的降低产品的生产成本。
