Light Weight Insulation Mullite Refractory Bricks B5 For Industrial Kiln
Mullite brick is a kind of quality refractory insulation materials
for resisting high temperature with features of light weight, low
thermal conductivity, thermal insulation and high compression
strength in the high temperature furnaces or kilns. lightweight
bricks are mainly used for the top of hot blast stove, stack and
bottom of blast furnace, regenerative chamber of glass melting
furnace, lining of ceramic high temperature furnace and so on.
Mullite brick is manufactured with mullite as the main crystal
phase and contains about 65~75% alumina content. Mullite Insulation
Refractory Brick has high refractoriness that reaches up to 1790 ℃.
Its apparent initial softening temperature is about 1600~1700 ℃.
Its cold crushing strength is about 70~260MPa.
Mullite Insulation Refractory Brick can be classified into
different types of 1350 lightweight brick, 1450 lightweight brick
and 1550 lightweight brick according to different service
temperature and into Lightweight Mullite Brick and Heavy Mullite
Brick according to different bulk density.
Mullite brick is a kind of quality high temperature materials with the following excellent performance.
Performance:
Low thermal conductivity and Low heat capacity
High Purity and low impurity content
Excellent high temperature strength
Good thermal shock resistance
Low expansive conductivity
Great resistance to acid and alkali erosion
Lightweight Mullite Insulating Bricks Features:
1.Excellent compression strength
2.Excellent heat stability
3.Low thermal conductivity
4.Low heat storage
5.High alumina, low iron and alkali flux content
6.Accurate dimension
7.designed packaging
