Magnesium-manganese spinel refractory material as well as preparation method and application thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a magnesium-manganese spinel refractory material as well as a preparation method and application thereof. The magnesium-manganese spinel refractory material is prepared by sintering the following preparation raw materials in parts by mass: 75-85 parts of magnesia, 10-20 parts of magnesium aluminate spinel, 1.5-5.0 parts of an aluminum compound, 1.0-5.0 parts of a manganese compound, 1.0-5.0 parts of a magnesium compound and 2.0-3.5 parts of a binding agent. In the invention, the aluminum compound and the manganese compound can form a manganese-aluminum spinel mineral phase, the magnesia, the magnesium compound and the aluminum compound can form a magnesium-aluminum spinel mineral phase, and a periclase mineral phase in the magnesia, the manganese-aluminum spinel mineral phase and the magnesium-aluminum spinel mineral phase are co-melted to form a stable structure, so that the volume stability and the chemical stability of the magnesium-manganese spinel refractory material are improved, and the kiln coating hanging performance, the thermal shock performance and the chemical erosion resistance of the magnesium-manganese spinel refractory material are further improved.
本发明属于耐火材料技术领域，具体涉及一种镁锰尖晶石耐火材料及其制备方法和应用。本发明提供了一种镁锰尖晶石耐火材料，由包括以下质量份数的制备原料烧结得到：75～85份镁砂，10～20份镁铝尖晶石，1.5～5.0份铝化合物，1.0～5.0份锰化合物，1.0～5.0份镁化合物和2.0～3.5份结合剂。在本发明中，铝化合物和锰化合物会形成锰铝尖晶石矿物相，镁砂、镁化合物和铝化合物会形成镁铝尖晶石矿物相，镁砂中的方镁石矿物相、锰铝尖晶石矿物相和镁铝尖晶石矿物相共熔会形成稳定的结构，从而提高镁锰尖晶石耐火材料的体积稳定性和化学稳定性，进而提高镁锰尖晶石耐火材料的挂窑皮性能、热震性能和抗化学侵蚀性。
