1.Description

Light weight high alumina 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

3.Application

Light weight high alumina insulation brick can be in direct contact with the flame,this insulating brick can be used as inner lining brick of industry kilns wall and industry furnance.such as blast furnace, hot blast stoves ,electric arc furnace, cement kiln,melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other thermal industrial equipment.
