High Alumina high temperature insulation Kiln Refractory Bricks Lightweight for Rotary Kiln

Application

By using the products widely in insulating layers of various thermal equipments for example blast furnace, hot blast furnace, coke oven and linings where no high temperatures melt corrosion occurs.


Features:

Characterized by low bulk density, maximum service temperature is 1350C., high cold crushing strength, 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, and productivity and significant economic results can be achieved.


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.
