Alumina Bubble Brick
Alumina bubble bricks is a high-temperature thermal insulation refractory material.
It is made of molten blown alumina bubble spheres, a compound bonding agent, shaped by vibration and fired at high temperatures.
The low density and low thermal conductivity of zirconia bubble ball brick can reduce both heat loss and heat storage.
Therefore, it can reduce energy consumption and reduce the self-weight of the high-temperature furnace as a high-temperature lining material in metallurgy, petroleum, chemical industry, electronics, and other thermal engineering equipment in direct contact with flame, and it is used with good effect.

Advantages Of Alumina Bubble Sphere Brick
Reducing the weight of the furnace body, transforming the structure, saving materials, and saving energy, will achieve significant results.
1. High Use Temperature
Can reach more than 1750 degrees, with good thermal stability. The small change rate of the re-burning line, longer use.
2. Optimize The Structure And Reduce The Weight Of The Furnace Body
Now with high-temperature resistant materials are the heavy brick bulk density of 2.6-3.0g/cm, while alumina bubble ball brick only 1.1-1.5g/cm, the same volume of a cubic meter, the use of alumina bubble ball brick can reduce the weight of 1.1-1.9 tons.
3. Material Saving
Reach the same use temperature, such as the use of heavy bricks whose price and alumina bubble ball brick price is comparable, and also need considerable insulation layer refractory materials. If you use alumina bubble ball brick, each cubic meter can save 1.1-1.9 tons of heavy brick use, more can save 80% of the refractory insulation material.
4. Energy Saving
Alumina bubble ball has obvious heat preservation characteristics, and low thermal conductivity, which can play a very good heat preservation effect. Reduce heat dissipation, and improve thermal efficiency, to play the purpose of saving energy. The energy-saving effect can be more than 30%.

Performance and Application of Alumina Bubble Sphere Brick
Alumina bubble spheres brick and their products are a kind of light refractory material with high-temperature resistance and excellent energy saving, which are very stable in use under various atmospheres.
Especially in the application on the high-temperature kiln at 1800℃.
Bubble spheres brick can be used as high temperature and ultra-high temperature thermal insulation filler, high-temperature refractory concrete lightweight aggregate, high-temperature castable material, etc.
Bubble ball bricks can be used for high-temperature energy saving (>30%) inverted flame kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nit riding furnace, etc.
Reducing the weight of the furnace body, transforming the structure, and saving materials, and energy, all will achieve an obvious effect.
Alpha-alumina powder is made of high-quality industrial alumina as raw material, produced by a new high-temperature inverted flame kiln and scientific calcination process, with manual selection, clear grading, fewer impurities, and high conversion rate, stable shrinkage rate, and good consistency.
With the development of science and technology, new bubble sphere materials have attracted the attention of various parties at home and abroad, and there are already bubble sphere bricks made of glass, ceramic, and carbon in foreign countries, and they have begun to be applied in many fields of science and technology.
In addition to high-temperature resistance and good heat preservation, bubble sphere refractory bricks also have good thermal shock stability and high strength. Because of the small bulk density and small heat capacity of bubble sphere material, it can improve the thermal efficiency of the high-temperature furnace, shorten the production cycle, and also greatly reduce the weight of the furnace body. It can be directly used as the lining of high-temperature furnaces. Alumina bubble sphere bricks and their products can be used for a long time below 1800℃. It also has good chemical stability and erosion resistance at high temperatures. It is very stable for use under a hydrogen atmosphere.
Alumina Bubble Sphere Brick Application FAQ
1. When applying alumina bubble sphere brick, the rate of raising the temperature when baking should not be too fast, otherwise, it will cause cracks and reduce the compressive strength and service life.
2. Usually not used to touch the location of slag corrosion, to prevent destruction due to slag corrosion.
3. Application relative to the sex should be alumina bubble ball brick drilling mud masonry wall.
