good job and nice quality! Hope our next business

—— Carsten Schmickler

very nice company.waiting for my next visit

—— Neetu Arora

good quality, but price is higher than other supplier.

—— Bipin Vagal

thank you for your products and service. During the project, the staff from your company cooperated with our side perfectly. The goods are all follow our order. The after-sale service also good.

High Alumina Light Weight 0.8g Insulation Bricks

 

Definition:

 

   

High Alumina Light Weight 0.8g Insulation Bricks is also called high alumina insulating brick. It contains more than 48% Al2O3 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.

 

High Alumina Light Weight 0.8g Insulation Bricks 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.

 

 

Advantage:

 

 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.

 

Application:

 

  High Alumina Light Weight 0.8g Insulation Bricks ,also know as high alumina insulation brick. The lining and the heat insulation layer of the kiln ,and the part of the erosion of the material without strong high temperature meiting .The surface contact temperature shall not be higher than 1350℃.
High qulity high alumina bricks can be used in direct contact with the flame of the furnace lining ,but should not be used directly by slay erosion occasions.
