Lightweight thermal insulation bricks Lightweight thermal insulation refractory brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.

Lightweight thermal insulation bricks Lightweight thermal insulation refractory brick are mainly made of bauxite clinker, combined with clay as raw materials, mixed with binders and sawdust.

 

Lightweight thermal insulation bricks Lightweight thermal insulation 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.
LLightweight thermal insulation bricks Lightweight thermal insulation refractory 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.

 

 

Features:

1 .High degree of fire resistance, high purity products can reach 1650-1800℃.
2. Good thermal shock resistance.
3. Chemical stability.
4. Low density, good thermal insulation effect.
5 .Low thermal conductivity, stable quality.

 

Compared with dense refractory bricks, JM 28 Mullite Insulation Standard Brick have the following advantages:


(1) With low heat storage and high thermal efficiency, it can speed up the turnover of intermittent operation kilns, improve production efficiency, reduce fuel consumption and save energy.


(2) Low thermal conductivity, which can reduce the thickness of the furnace wall and roof, reduce the quality of the furnace body, and simplify the structure of the furnace.


(3) The furnace temperature can become uniform. Conducive to improving product quality.


(4) The temperature outside the furnace is low, which is convenient for operation, improves labor efficiency, and improves labor conditions for kiln installation and discharge.

 

 

Application:

  • Nonferrous Metal Furnace
  • Rotary & Shaft Kiln
  • Various Incinerator
  • Reheating Furnace
  • Permanent Lining For EAF Ladle
  • General Industrial Furnace etc.
