Abrasion-resistant anti-erosion pouring material for cement kiln tertiary air duct
The invention relates to the field of refractory materials, in particular to an abrasion-resistant anti-erosion pouring material for a cement kiln tertiary air duct. The abrasion-resistant anti-erosion pouring material is prepared from, by weight, 20-50 parts of white corundum, 18-30 parts of mullite M45, 15-40 parts of fused magnesium aluminate spinel, 10-30 parts of fused hercynite, 3-5 parts of zirconium carbonate, 3-5 parts of silicon carbide, 2-3 parts of silica micro powder, 2-8 parts of alumina micro powder, 0.1-1 part of sodium tripolyphosphate and 5-10 parts of additionally added binding agents. The fused magnesium aluminate spinel comprises 15-25 parts of fused magnesium aluminum pointed crystal particles ranging from 5 mm to 8 mm in particle size, 5-20 parts of fused magnesium aluminum pointed crystal particles ranging from 3 mm to 5 mm in particle size, 5-15 parts of fused magnesium aluminum pointed crystal particles ranging from 1 mm to 3 mm in particle size and 5-15 parts of fused magnesium aluminum pointed crystal particles ranging from 0 mm to 1 mm in particle size. The fused hercynite comprises 10-20 parts of fused hercynite particles ranging from 5 mm to 8 mm in particle size, 5-15 parts of fused hercynite particles ranging from 3 mm to 5 mm in particle size, 5-10 parts of fused hercynite particles ranging from 1 mm to 3 mm in particle size and 5-10 parts of fused hercynite particles ranging from 0 mm to 1 mm in particle size. The white corundum is formed by mixing white corundum with the particle size ranging from 1 mm to 5 mm with white corundum with the particle size ranging from 6 mm to 10 mm according to the mass ratio of 1:3-5. The pouring material is high in abrasion resistance, good in high temperature resistance and high in thermal shock resistance.
