Why industrial kilns better be built with lightweight mullite insulation bricks ? 2

Most of the mullite insulation brick used in high temperature kiln industry are classified according to its working temperature:

mullite-insulation-brick

Low temperature lightweight mullite insulation brick, its working temperature is 600--900℃, such as light diatomite brick;
Medium-temperature lightweight mullite insulation brick, its working temperature is 900--1200℃, such as lightweight clay insulation bricks;
High-temperature lightweight mullite insulation brick, its working temperature is greater than 1200 ℃, such as lightweight corundum brick, mullite insulation bricks, alumina hollow balls brick, etc.
Mullite insulation bricks are mostly used as the insulation layer, lining and insulation of kilns. In recent years, newly developed light weight mullite insulation bricks, alumina hollow ball bricks, high alumina poly light bricks, etc., because they are produced with kyanite raw material, they can directly contact the flame.
Due to the use of mullite insulation bricks, the thermal efficiency of industrial high-temperature kilns has been greatly improved. Therefore, the wide application of mullite insulation bricks is an inevitable phenomenon.
