Description

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.
