Description

Alumina hollow ball bricks, also known as Alumina bubble brick and products, are made of alumina hollow spheres and alumina powder as the main raw materials, combined with other binders, and fired at a high temperature of 1750 degrees. It is a kind of energy-saving insulation material for ultra-high temperature materials. Alumina hollow sphere is a new type of high temperature insulation material. It is made by melting industrial aluminum oxide in an electric furnace. The crystal form is a-Al2O3 microcrystal. The alumina hollow sphere is the main body, and can be made into various shapes. The maximum use temperature is 1800 ° C, the mechanical strength of the product is high, several times that of the general lightweight product, and the bulk density is only one-half of the corundum product. It has been widely used in high-temperature and ultra-high temperature furnaces such as petrochemical industrial gasifiers, carbon black industrial reactors, metallurgical industrial induction furnaces, etc., and has achieved very satisfactory energy-saving effects.

Characteristic

Advantage
Reducing the weight of the furnace, renovating the structure, saving materials, and saving energy will all achieve significant results.
1, the use of high temperature:
It can reach more than 1750 degrees and has good thermal stability. The reburning line has a small rate of change and is used for a longer period of time.
2. Optimize the structure and reduce the weight of the furnace:
Now the high temperature resistant materials are all heavy bricks with a bulk density of 2.6-3.0g/cm, while alumina hollow ball bricks are only 1.1~1.5g/cm, the same cubic meter volume, using alumina hollow ball bricks can reduce 1.1- 1.9 tons of weight.
3. Saving materials:
To achieve the same temperature of use, such as the use of heavy bricks, the price is comparable to the price of alumina hollow ball bricks, and also requires considerable insulation refractories. If you use alumina hollow ball bricks, you can save 1.1-1.9 tons of heavy bricks per cubic meter, and save 80% of refractory insulation materials.
4. Save energy:
The alumina hollow sphere has obvious heat preservation characteristics and low thermal conductivity, which can play a good thermal insulation effect, reduce heat dissipation and improve thermal efficiency, thereby saving energy. Energy saving effect can reach more than 30%.

Application
Especially applied on high temperature kiln at 1800 °C. Hollow balls can be used for high temperature, ultra high temperature insulation fillers, high temperature refractory concrete lightweight aggregates, high temperature castables, etc. Alumina core bricks can be used for high temperature energy saving (>30%) downdraft kiln, shuttle kiln, molybdenum wire furnace, tungsten rod furnace, induction furnace, nitriding furnace, etc. It will achieve obvious results in reducing the weight of the furnace, transforming the structure, saving materials and saving energy.
