Lightweight refractory insulation bricks have developed rapidly in recent years, especially high-alumina mullite bricks, light-weight mullite bricks, mullite fibers and high-alumina mullite fibers, which are the necessary material for making energy saving sanitary ceramics kilns.
Lightweight insulation brick is a kind of refractory fire brick that is of low alumina content. It is different from ordinary building thermal insulation brick.
Lightweigh refractory insulation bricks are suitable for various industrial furnace hot surface lining in the temperature range of 900℃~1650℃. Such as: annealing furnace, carbonization furnace, tempering furnace, oil refining heating furnace, cracking furnace, roller kiln, tunnel kiln, etc.
Characteristics of lightweight refractory insulation bricks are low thermal conductivity, low thermal capacity, good thermal shock resistance, good corrosion resistance in acid and alkali atmospheres, etc.
