Product description
Bnz insulating firebrick: refers to the content of Al2O3 in more than 46% of light firebrick. The brick made of natural high alumina clinker is called ordinary light high alumina brick. Light corundum brick is made of fused alumina and its main crystal phase is corundum. Lightweight high aluminum bricks are usually produced by the foam method, with a volume density of 0.4-1.35g/cm3, a porosity of 66%-75%, a compressive strength of 1.3-8.1MPa, and a thermal conductivity of 0.291-0.582W (m.k). Ordinary light high aluminum brick using temperature of 1350-1500℃, suitable for hydrogen, CO and other gases as the protective atmosphere of the kiln. Lightweight corundum brick can be used as furnace lining with the temperature reaching 1650-1800℃, which can directly contact the flame, but it should not be eroded by slag.
Advantages of bnz insulating firebrick:
◆High compressive strength
◆Widely application with different bulk density
◆Good insulation performance, low thermal conductivity
◆Customerize mould according to different size requirements for free
Application of bnz insulating firebrick
Used in refractory hot surface linings and backing insulation layers of other refractory materials, Refractory insulation materials for industrial furnaces such as cracking furnace tubular heating furnaces, reforming furnaces, hot blast furnaces, ladle insulation linings, shuttle kilns, tunnel kilns, ceramic track kilns, and push plate kilns in the steel, metallurgical, and chemical industries.
