Anti-slagging high-temperature wear-resistant composite material and preparation method thereof
The invention discloses an anti-slagging high-temperature wear-resistant composite material. The material is prepared from corundum fine powder, aluminum dihydrogen phosphate, kyanite, pure calcium aluminate cement, silicon dioxide micro powder, rho-aluminum oxide, fine ceramic powder, magnesium aluminate spinel, sodium tripolyphosphate and explosion-proof fibers. The material has high strength and good wear resistance and can resist the abrasion of solid materials and the scouring of hot air flow; the composite material has excellent volume density, stability and acid and alkali resistance soas to resist erosion of acid and alkali substances in a furnace; the composite material has good thermal shock stability so as to resist damage of the temperature change of the furnace to the material; and the composite material has good erosion resistance so as to avoid cracking of the lining of the furnace due to erosion, so that the service life of the furnace is greatly prolonged.
本发明公开了一种抗结渣高温耐磨复合材料，由刚玉细粉、磷酸二氢铝、蓝晶石、纯铝酸钙水泥、二氧化硅微粉、ρ‑氧化铝、精细陶瓷粉末、镁铝尖晶石、三聚磷酸钠、防爆纤维组成。本材料具有高强度和良好的耐磨性，以抵抗固体物料的磨损和热气流的冲刷，具有优良的体积密度及稳定性和耐酸碱性，以抵抗炉内酸碱性物质的侵蚀，具有良好的热冲击稳定性，以抵抗炉温的变化对材料的破坏，具有良好的抗侵蚀能力，以避免侵蚀而引起炉衬崩裂，使用周期大大延长。
