Tertiary air duct wear-resistant anti-erosion pouring material
The invention relates to the field of refractory materials and especially relates to a tertiary air duct wear-resistant anti-erosion pouring material. The tertiary air duct wear-resistant anti-erosion pouring material comprises, by weight, 20-50 parts of white alundum, 18-30 parts of mullite M45, 15-40 parts of fused magnesia-alumina spinel, 10-30 parts of fused hercynite, 3-5 parts of zirconium carbonate, 3-5 parts of silicon carbide, 2-3 parts of silica powder, 2-8 parts of alumina powder, 0.1-1 part of sodium tripolyphosphate, 5-10 parts of an applied binder, 4-8 parts of aluminum oxynitride, 5-9 parts of Lafarge cement and 3-5 parts of water. The fused magnesia-alumina spinel comprises 15-25 parts of fused magnesia-alumina spinel particles with sizes of 5-8mm, 5-10 parts of fused magnesia-alumina spinel particles with sizes of 3-5mm, 5-15 parts of fused magnesia-alumina spinel particles with sizes of 1-3mm and 5-15 parts of fused magnesia-alumina spinel particles with sizes of 0-1mm. The fused hercynite comprises 10-20 parts of fused hercynite particles with sizes of 5-8mm, 5-15 parts of fused hercynite particles with sizes of 3-5mm, 5-10 parts of fused hercynite particles with sizes of 1-3mm and 5-10 parts of fused hercynite particles with sizes of 0-1mm. White alundum comprises white alundum with granularity of 1-5mm and white alundum with granularity of 6-10mm according to a mass ratio of 1: 3-5. The pouring material has high wear resistance, good high temperature resistance and good thermal shock resistance.
