Tertiary air duct curve prefabricated component for cement kiln
The present invention provides a with tertiary air duct curve prefabricated component for a cement kiln, and aims to resolve the problem of poor anti-erosion performance of the tertiary air duct curve of the prior art. The tertiary air duct curve prefabricated component for the cement kiln comprises the following components by weight parts of: 15-25 parts of 5-8mm black corundum, 15-20 parts of 3-5mm black corundum, 10-15 parts of 1-3mm black corundum, 10-15 parts of 0-1mm black corundum, 10-20 parts by 0-1mm of silicon carbide, 6-10 parts of silicon carbide powder not larger than 200 mesh, 5-10 parts of brown alumina powder not larger than 200 mesh, 4-7 parts of calcium aluminate cement, 3-5 parts of alumina powder, 4-6 parts of silica powder, 0.10-0.15 part of a water reducing agent, 0.01-0.02 part of explosion-proof fiber and 0.5-1 part of heat-resistant steel fiber. The invention uses black corundum and silicon carbide as the main materials for the tertiary air duct curve prefabricated component, and the black corundum can make the matrix and aggregate fully connect and cement at high temperature, effectively fill the pores of aggregate and significantly improve the high temperature properties of the material, thereby increasing the abrasion resistance and alkali erosion resistance of the tertiary air duct curve inner liner.
