pure white high temperature mullite Insulation bricks
pure white high temperature mullite Insulation bricks 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 JM-23 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.
