Low thermal conductivity mullite brick is also known as low thermal conductivity multilayer mullite brick. The product is a composite structure composed of working layer, thermal insulation layer and high fiber thermal insulation layer. The product is formed at one time and has a compact structure, which solves the problems of cracks and peeling caused by the mismatch of thermal conductivity of composite materials. The low thermal conductivity mullite brick is a new type of refractory brick, which is resistant to high temperature, brain erosion, corrosion, thermal shock, and heat insulation. After one year of use in the transition zone and decomposition zone of the cement kiln, it has significant performance and use effect compared with the silica mullite brick.
1. It still has a thickness of 13-15cm, and can be used for more than 3 months, extending the service life
2. The surface temperature of the cement kiln barrel has been reduced by 50-80 ℃, saving about 1100 tons of standard coal every year, with remarkable energy saving effect
3. Reduce carbon dioxide emissions by about 2700 tons, sulfur dioxide emissions by about 20 tons, and nitrogen oxide emissions by about 20 tons each year, with obvious environmental protection effects.
In a word, the low thermal conductivity mullite brick, after being used in more than 50 cement kilns, not only fully meets the use requirements, but also obviously realizes the purpose of energy saving, power saving, environmental protection and life extension, and has won praise from users
