Product Description
High alumina insulating bricksHigh alumina insulating bricks are also known as high alumina heat insulating bricks. It is a new type of lightweight insulating material which contains approximately 48% alumina,mullite and glass phase or corundum. Light weight alumina insulating brick adopts inorganic 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. 
Features--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,productivity and significant economic results can be achieved.
ApplicationLight Weight High Alumina Insulating Brick is widely used in lining or insulating layers of various industrial furnaces, and kilns in petrochemical, machinery, ceramic industry, such as:--lining and insulating layer of high temperature kilns.--carbon black stove, gasifier, hydrogen manufacturing furnace and shuttle kiln,etc. advantage:1.light weight
2.low density
3.high strength,good thermal shock resistance
4. Low heat storage, low thermal conductivity
5.saving energy
6.Precise size
7.good thermal insulation effect
8.good quality and low price
