Insulating refractory bricks (1260C-1600C)
Insulation refractory brick is a kind of high-quality refractory and heat-insulating material with high temperature resistance. Insulation refractory bricks are mainly used for hot blast stove top, blast furnace chimney and bottom, glass melting furnace regenerator, ceramic high temperature furnace lining, etc.
The insulating refractory brick is made of mullite as the main crystal phase, and the alumina content is about 65~75%. Mullite insulation bricks have high refractoriness up to 1790℃. Its apparent initial softening temperature is about 1600-1700 °C. Its cold pressing strength is about 70~260MPa.
Mullite heat insulating refractory bricks can be divided into 1350 heat insulating refractory bricks, 1450 heat insulating refractory bricks and 1550 heat insulating refractory bricks according to different operating temperatures, and can be divided into light mullite bricks and heavy mullite bricks according to different bulk weights brick.
