Lightweight thermal insulation brick Mullite thermal insulation brick Kiln lining thermal insulation brick JM23 JM26
Insulating Firebrick 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. Insulating Firebricks 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.
Insulating Firebrick 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 Insulating Firebrick, 1450 Insulating Firebrick and 1550 Insulating Firebrick according to different service temperature and into Lightweight Mullite Brick and Heavy Mullite Brick according to different bulk density.
