Refractory brick factory supply IFB series Insulating firebrick
grade 23 26 28 30 32 for Refining Furnace and hot blast stove
Product Description
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.
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.
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.
Insulating firebrick 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.
