Light weight high temperature heat insulating bricks soft fire brick insulating refractory brick
Introduction of insulating refractory brick:
Light weight insulating refractory brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
The alumina content of more than 48% , mainly composed of corundum mullite and glass phase or light refractory materials.Volume density of 0.4 ~ 1.35g/cm3 . The porosity is 73% ~ 66% ,the compressive strength is 1 ~ 8MPa .Better thermal shock resistance .Usually use high alumina bauxite plus a small amount of clay ,after grinding with gas or foam to form mud casting ,forming 1300 ~ 1500℃ firing .Sometimes can also be used to replace part of industrial alumina bauxite.
Feature of insulating refractory brick:
1 .High degree of fire resistance, high purity products can reach 1650-1800℃.
2. Good thermal shock resistance.
3. Chemical stability.
4. Low density, good thermal insulation effect.
5 .Low thermal conductivity, stable quality.
