An alumina based Composite wear plate and preparation method

An alumina based Composite wear plate and a preparation method, belonging to the technical field leaning coking device. Composite wear plate characterized in that the parts by weight composition is the following: Al2O3 powder 75 to 85 parts of zirconium silicate powder 10 to 15 parts of cooked 2 to 6 parts of talc, 2 to 4 parts by Suzhou clay, fused silica, 2 to 6 parts, CeO2 0 ~ 3 parts, Y2O30 ~ 3 parts. Preparation method characterized by: the total mass of the raw material feed was added 30% water and 3% of an organic dispersant ball mill mixing the slurry rear; then used directly in slip casting or spray granulator after molding; Finally, with a weak reducing atmosphere, low firing temperature of the firing holding time longer wear plate firing system; the present invention while maintaining excellent wear resistance and high temperature properties of alumina ceramic, it has greatly improved resistance material thermal shock properties, good to meet the pilot power requirements of the turner environmental conditions of the thermal shock resistance.
