Lightweight standard size high alumina fire resistant heat insulation brick for furance lining
Lightweight standard size high alumina fire resistant heat insulation brick for furance lining
1.Description
High alumina fire resistant heat insulation brick is made of high purity high alumina bauxite as the main material by shaping at high pressure and sintering at high temperature.High alumina insulating brick is a kind of porous material with Al2O3 content above 48%. Its refractoriness is 1770-2000 °C.The bulk density is 0.4-1.35g/cm3,the porosity is 66%-73%, crushing strength is 1.3-8.1MPa, thermal conductivity is 0.291-0.582W/(m.K) (1350°C)
2.Feature
1.Low levels of iron and other impurities
2.High mechanical intensity
3.High refractoriness, can contact with the flame directly, suitable for various atmosphere
4.High porosity, low volume density, low thermal conductivity
5.Good heat insulating performance and energy-efficient
6.Excellent thermal shock resistance
7.Strong resistance to the corrosive gas and slag
8.Long service life
