Definition:
High Alumina Insulating Refractory Brick is an ideal insulating refractory refractory material, with advantages of high strength, low thermal conductivity, good insulation property and low price. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
Light weight high alumina brick is also called high alumina insulating brick. It contains more than 48% Ai2O3 and mainly consists of mullite and glass phase or corundum. It is usually made of high bauxite and a small amount of clay. After the raw materials are grounded, it is made into mud. Then it is cast and molded and fired at 1300~1500℃. Sometimes industrial alumimum is used to replace bauxite. Inorganic matter is added as ignition loss substance in order to increase the porosity of the refractory.
Advantage:
1. Excellent strength at ambient and elevated temperatures.
2. High compressive strength.
3. Very low levels of iron and other impurities.
4. Lightweight and energy-efficient.
5. Lower heat storage than denser refractory.
6. Heats quickly and economically to operating temperature.
Application:
The application of High Alumina Insulating Refractory Brick
1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace
