Alumina Silica Fire Brick
Alumina silica fire brick contains Al2O3 and SiO2 refractory materials, alumina silica brick is a series of aluminum silicon refractory brick. Aluminum silicon series firebrick has a wide range of applications and occupies a very important position in the refractory application industry. alumina silicate bricks dosage accounts for more than 40% of the whole refractory products.
Alumina Silica Fire Brick Description
Alumina silica fire brick is a kind of alumina silica refractory materials, alumina silicate refractory brick has features of high refractoriness, good erosion resistant and high strength. Aluminum silicate refractory brick includes many types of firebricks such as silica brick, fireclay brick, High alumina brick, mullite brick and corundum Brick. alumina silica fire brick can be used for all kinds of thermal equipment.
Classification of Alumina Silica Fire Brick
According to the order of increasing content from SiO2 to Al2O3, aluminum silicon fire brick is classified into the following categories
Silica brick: the content of SiO2 is greater than 93%,
Clay brick: the content of Al2O3 is 30%-48%,
High alumina brick: the content of Al2O3 is greater than 48%,
Mullite brick: the content of Al2O3 is greater than or equal to 72%, and the content of SiO2 is greater than or equal to 28%,
Corundum brick: the content of Al2O3 is more than 90%.
Application of Alumina Silica Fire Brick
Silica brick is mainly used to build coke oven, glass kiln, ceramic kiln, carbon calcinations furnace and is not suitable to be used in heating equipment with temperature fluctuation under 600 ℃.
Clay brick is always used in blast furnace, hot blast heater, heating furnace, power boiler, lime kiln, rotary kiln, ceramic kiln and calcining kiln.
High alumina brick is mainly used in steel manufacture, non-ferrous metals industry and other industries.
Mullite brick is used in all kinds of industry furnace hot-face lined and backing lining in metallurgical industry, petrochemical industry, building materials industry, ceramic industry, and mechanical industry.
Corundum brick can be used in blast furnace, hot blast stove, glass furnace and etc.
