Aluminosilicate ceramic fiber is a new type of refractory insulation material. Statistics show that using aluminum silicate ceramic fiber as refractory materials or insulation materials for resistance furnaces can save energy consumption by more than 20%, and some as high as 40%. Because aluminum silicate ceramic fiber has the characteristics of high temperature resistance, good chemical stability and low thermal conductivity, the use of aluminum silicate ceramic fibers as the lining of resistance furnaces in non-ferrous metal foundries can shorten furnace heating time, lower furnace external wall temperature, lower furnace energy consumption.
Aluminum silicate ceramic fiber has below characteristics
(1)High temperature resistance
Ordinary aluminum silicate ceramic fiber is an amorphous fiber made of refractory clay, bauxite or high-alumina raw materials in a molten state by a special cooling method. This is because the thermal conductivity and heat capacity of aluminum silicate ceramic fiber is close to those of air. It consists of solid fibers and air, with a void ratio of more than 90%. Since a large amount of low thermal conductivity air is filled in the pores, the continuous network structure of solid molecules is destroyed, so it has excellent heat resistance and heat preservation performance.
Next issue we will continue to introduce characteristics of aluminum silicate ceramic fiber. Please stay tuned!
