Low density, aluminum silicate fiber shape are over 75% lighter than lightweight insulation brick furnace lining, and 90% to 95% lighter than lightweight castable furnace lining. If plate insulation is used, it can greatly reduce the steel structure load of the kiln and extend the service life of the furnace body. The heat capacity of ceramic plates is only about 1/10 of that of lightweight heat-resistant lining and lightweight castable lining, with fast start-up and shutdown speeds, reducing energy consumption in temperature control operations. Low thermal conductivity: about 1/10 of the lightweight heat-resistant lining (castable), with good insulation effect.
With the development of refractory fiber production technology and application technology, aluminum silicate fiber shaped parts have achieved serialization and functionalization. The products can meet the usage requirements of different temperature ranges from 600 ℃ to 1400 ℃ in terms of usage temperature, and can meet the usage requirements of thermal insulation materials for different industrial furnaces in various industries.
