The light weight mullite bricks contains high porosity, which can save more heat and therefore reduces the cost of fuel. Meanwhile the light weight means less heat storage capacity, so less time is required when the kiln is heated or cooled. Faster periodic operation is workable.
It can be applied at the temperature range from 900 to 1600 ℃.
It is mainly used as kiln lining in high temperature(less than 1700 ℃) kilns of ceramics, petrochemical, metallurgy and machinery.
Low thermal conductivity, low heat capacity, low impurity content
High strength, excellent thermal shock resistance, erosion resistance
Ceramics roller kiln and shuttle kiln: standard brick, roller passage hole brick, hanger brick,
Metallurgy industry: hot blast furnace; inner lining of foundry kilns
Power industry: power generation and fluidised bed equipment
Electrolytic Aluminium industry: kiln inner lining
