Product Description:

High alumina lightweight 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.


anti -spalling high alumina brick 
Thermal conductivity low to 0.2W/m.k 
Bulk density 0.5g/cm3 
Application temp from 1250 t

Light WeightHigh Alumina Refractory Insulating Brick


This series of High Alumina Insulating Refractory Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature 



 By using the products widely in insulating layers of various thermal equimentsfor example bast furnace,hot blast furnace,coke oven and linings where no high temperatures meltcorrosion



Characterized by low bulk density,maximum service temperature is 1350C., high cold crushing strengh,size precision and hold the most stable and lowest thermal conductivity of all insulating refractory bricks at present.

The total weight of the furnace body and walls thickness can be reduced effectively,thermal efficiency and working condition can be improved,energy consumption can be lowered,produtivity and significant economic results can be achieved.
