Definition:
Insulating Refractory Brick generally refer to refractory bricks with a density less than 1.3 g/cm3. Due to the characteristics of low density, high porosity, small thermal conductivity, good thermal insulation and certain compressive strength, light-weight refractory bricks have been widely used in heat treatment equipment.
Insulating Refractory Brick is also known as high aluminum insulation brick. Lightweight refractory material with alumina content above 48%, mainly composed of mullite and glass phase or corundum. The bulk density is 0.4 to 1.35 g/cm3. The porosity is 66%～73%, and the compressive strength is 1～8MPa. Good thermal shock resistance.
The materials of ordinary light-weight heat-resistant refractory bricks are clay, high-alumina high-strength floating bead bricks, low-iron mullite, high-aluminum poly light-insulating refractory bricks, and diatomaceous earth heat-resistant refractory bricks.
For strength products, high-quality plate-like corundum and mullite are used as aggregates, sillimanite composite is used as a matrix, special additives and a small amount of rare earth oxides are mixed, and then subjected to high-pressure molding and high-temperature firing.
Advantage:
(1) Light weight:
(2) Insulation and heat insulation:
(3) Sound absorption and sound insulation:
(4) Small shrinkage value:
(5) Impermeability:
(6) Environmental protection:
Application:
Insulating Refractory Brick mainly used for the insulating lining of hot surfaces or backing heat-insulating layers of other
refractory materials. The refractory linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, ubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc.
