refractory withstand high temperature insulating light weight high alumina brick used for boiler furnace

Light weight high alumina 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.

ميزة Of High alumina insulating brick :
1. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks.
3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.

Production Process of High alumina insulating brick:

High alumina insulating brick:Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment

Light weight high alumina brick has such advantages as high porosity, good insulation effect, high mechanical intensity, low thermal refractory fiber board conductivity and long service life. It has high cold crushing strengh,size precision and holds the most stable and lowest thermal conductivity of all insulating refractory brick at present. Its maximum insulating castable service temperature is 1350℃. Thermal efficiency and working condition can be improved, energy consumption can be lowered, productivity and significant economic results can be achieved.
Light weight high alumina brick is characterized by low bulk density. The total weight of the furnace body and walls thickness can be reduced effectively.
It has found a wide application in ceramics tunnel kiln, roller kiln, shuttle kiln, coking furnaces of iron and steel industry and other thermal equipment. It is mainly used in lining and insulating layer of areas without strong erosion by high temperature melts. When in direct contact with flame, the surface contact temperature can not be higher than 1350℃.
