Product Description

Mullite Insulation 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. Mullite Insulation 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.

Description for Mullite Insulation Brick
Mullite Insulation 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 Mullite Insulation Brick, 1450 Mullite Insulation Brick and 1550 Mullite Insulation Brick according to different service temperature and into Lightweight Mullite Brick and Heavy Mullite Brick according to different bulk density.

Mullite Insulation Brick Properties
Mullite Insulation Brick is a kind of quality high temperature materials with the following excellent 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

Mullite Insulation Brick Application
Mullite Insulation B rick is suitable for hot-face lining and backing of all kinds of industrial furnace in metallurgy industry, petrochemical industry, ceramic industry, machinery industry and building materials industry, such as cracking furnace, conversion furnace, heating equipment, refine equipment, regenerative apparatus, hot blast stove, soaking pit furnace, thermal treatment furnace, resistance furnace, tunnel kiln, roller kiln, bell kiln, glass melting furnace and so on.
