Brief introduction:
Mullite insulating bricks are high alumina refractories with mullite as the main crystalline phase which we call mullite lightweight insulating bricks. General alumina content of 65% to 75%. Mineral composition in addition to mullite, which contains low alumina also contains a small amount of glass phase and quartz; high alumina also contains a small amount of corundum.
Characteristics:
Low thermal conductivity, has a very good thermal insulation effect; high refractoriness; higher aluminum content in the reducing atmosphere still maintains good performance; high compressive strength in the hot state.
Application:
At present, it is widely used in the upper structure of glass melting kiln material channel brick, change plate, processing kiln upper structure, firing kiln, melting kiln, refining device, heating device, and other thermal insulation layer of thermal equipment.
