Pouring material for cement kiln tertiary air duct
The invention relates to a pouring material for a cement kiln tertiary air duct. The pouring material comprises aggregate and a matrix material according to a weight ratio of 2-8: 1-3. The aggregate has particle sizes of 1-10mm and the matrix material has the particle sizes of 0.1-0.5mm. The aggregate comprises, by weight, 28-50 parts of fused magnesia, 25-45 parts of modified white alundum, 5-15 parts of zirconium mullite and 8-20 parts of magnesium aluminate spinel. The matrix material comprises magnesia powder, silicon oxide fine powder, mullite powder, alumina fine powder and andalusite. The pouring material utilizes appropriate aggregate and the matrix material and has wear resistance and corrosion resistance, a uniform degree of expansion and good thermal shock stability. Through use of a fiber additive, pouring material integrality is improved, and pouring material flexural performances and anti-erosion performances are improved. The cement kiln tertiary air duct has the advantages of long service life, long replacement period, small production cost and high production efficiency under bad conditions.
