Mullite Insulating Refractory Brick Description:

Mullite Insulating Refractory 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.

lightweight 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 Insulation Brick Advantage:


1. Low thermal conductivity
2. High cold crushing strength
3. Perfect Energy saving

4. Stable volume

5. Excellent heat insulation

6. High intensity for pressure

7. Good thermal shock stability


Mullite Insulation Brick Application:



Metallurgy industry


Petrochemical industry


Ceramics industry


Aluminum industry


Glass industry



1. Low heat conductivity, with good thermal insulation effect

2. Low hot melting, due to low heat conductivity, it accumulates little heat to get obvious energy-saving in intermittent operation.

3. Low impurity content and low content of iron oxide & alkali metal oxide realize high refractoriness. High Al2O3 content makes it keep good performance under reducing atmosphere.

4. High thermal compressive strength

5. Accurate size increases construction speed, decreases fire clay usage, ensures strength and stability of masonry, prolongs the life span of lining.

6. It can be processed into special shapes to reduce brickwork amount and paving seam.



Mullite insulating brick can be used in high temperature kiln lining. Currently, it is widely used roof of hot-blast furnace, body and bottom of blast furnace, regenerative chamber of glass melting furnace, ceramic kiln, blind angle furnace lining of petroleum cracking system, shuttle kiln, roller kiln, linings of glass and petrochemical engineering furnaces.

In addition, in order to meet the production requirements of more clients and kilns, KERUI develops new products of different textures and shapes on the basis of originals, such as poly-light mullite brick tile, poly-light corundum brick, poly-light silicon brick, fire clay insulating brick, etc.
