Lightweight Insulating bricks are castable refractories that have great thermal insulation materials, which comes as a result of their small bulk density and low thermal conductivity.

 

Moreover, the lightweight insulating bricks brands have other features that are exclusive for thermal insulation lining of several thermal tools, and some lightweight insulating bricks can also be used in a straight line for work lining.

 

There are numerous insulating bricks manufacturers in china, so when considering to buy some for your next project, you have to look out for a professional and reliable manufactures of these products.

 

In this article, we would be talking about things you need to know about Lightweight insulating bricks. Follow thru to learn more.

 

Various Type of Lightweight Insulating Fire Brick And Their Properties

1. Lightweight high alumina brick is factory-made with foam method, its resistance to heat is decent and is widely used for thermal insulation.

 

2. Lightweight silica bricks have high refractoriness under load and great thermal stability

 

3. Silicon carbide lightweight insulating fire brick they have exceptional characteristics which are good resistance to erosion, crack resistance, and high-temperature power.

 

4. Diatomite brick is manufactured with natural porous raw materials, with a good thermal insulating material and thermal conductivity is low.

5. Zirconia lightweight insulating fire brick is produced with the foam method.

It has excellent properties of high melting point, high specific resistance, a high index of refraction, and a low thermal expansion coefficient.

It can be used in a super high-temperature furnace for thermal insulation.

 

6. Alumina Lightweight Insulating Fire Brick is made with the foaming process, low reheating linear change rate, and longer service life ability with good thermal strength.

It is used for thermal insulation in a super high-temperature heating system.

 

7. Zircon Lightweight Insulating Fire Brick is manufactured with foam process with good structures of little thermal conductivity and decent resistance to thermal shock, it can be used in great high-temperature furnace aimed at thermal insulation.

 

8. Calciclase Lightweight Brick is made of CaO, Al2O3, and SiO2 as the leading components, its bulk density is very low and resistance to chipping is great.

 

9. Magnesian Lightweight Insulating Fire Brick is great with heat resistant ability and extraordinary service temperature.

 

10. Lightweight Fireclay Brick is manufactured with a firing method that can be used widely

 

11. Mullite Cordierite Lightweight Insulating Fire Brick has a low thermal expansion and good resistant properties.

 

Manufacturing Process of Lightweight Insulating Bricks

Lightweight Insulating bricks are also shaped refractory bricks that possess a porous structure with high porosity and thermal insulating properties.

 

Their major characteristics are lightweight, low thermal conductivity, low bulk density, energy-saving, and its ease of construct. They can serve at a temperature of about 900 – 2000oC, and when doing this, you should consider the following factors;

 

1. You should cut into blocks from a naturally porous light weigh protolithic material.

2. Your raw material for bricks making should be natural lightweight substances.

3. Combustible material that can burn with ease should be added into a pug.

4. The foaming agent should also be added to the pug.

 

Conclusion

There are several types of insulating fire bricks according to the different raw material structures used.

 

Since the lightweight insulating bricks brands are manufactured independently, it is better to purchase from dependable manufacturers that has a good understanding of which type will suite your project.
