High Temperature High Alumina Insulation Brick Lightweight Low Thermal Conductivity Energy Saving

Light Weight High Alumina Brick, also known as high-aluminium heat insulating brick, Light weight high alumina bricks contain more than 48% alumina oxide. The refractory temperature can reach 1770 degrees, and the usable temperature can reach 1550 degrees.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.

Introduction of High Alumina Insulation Brick

Light Weight High Alumina Brick, also known as high-aluminium heat insulating brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulating heat. Light weight high alumina bricks contain more than 48% alumina oxide. This kind of brick does not directly exposed to high temperature inside kilns or furnaces, it only built closely to the kiln wall as insulations. It is a good insulation refractory material, which has a high compressive strength, low thermal conductivity and good insulation quality.

High Alumina Insulation Brick Features

1. High refractoriness, can reach 1650-1800ºC, can contact with the flame directly, suitable for various atmosphere. 

2. High mechanical intensity.

3. Low levels of iron and other impurities. 

4. Good thermal shock resistance. 

5. Chemical stability. 

6. High porosity, low volume density, good thermal insulation effect,energy-efficient. 

7. Low thermal conductivity, stable quality. 

8. Excellent thermal shock resistance. 

9. Strong resistance to the corrosive gas and slag.
