Introducing alumina hollow ball bricks

Alumina hollow ball is a new type of high-temperature insulation material. It is made by melting and blowing industrial alumina in an electric furnace. The crystal shape is a-Al2O3 crystallite. With alumina hollow balls as the main body, it can be made into products of various shapes, with a maximum temperature of 1800 °C, high mechanical strength of the product, several times that of light products, and a bulk density of only half of corundum products. In gasifiers for the petrochemical industry. Carbon black industrial reactor. Metallurgical industry, induction furnace and other high temperatures. Ultra-high temperature kilns are widely used and the energy-saving effect is very satisfactory.

Alumina hollow ball brick is made of alumina hollow ball and alumina powder as the main raw material, combined with other binders, fired at 1750 °C. It is an ultra-high temperature material, energy-saving insulation material.

Peculiarity:

1. High operating temperature: up to more than 1750 degrees, good thermal stability, small change rate of reburning line,

2. Optimize the structure and reduce the weight of the furnace body: the commonly used high-temperature resistant materials are heavy bricks, the bulk density is generally 2.6-3.0g/cm, and the alumina hollow ball brick is only 1.1-1.5g/cm, the same 1M3 volume, and the weight of alumina hollow ball bricks can be reduced by 1.1-1.9 tons.

3. Save materials: the same temperature, the same price, if you use alumina hollow ball bricks, you can save 1 yuan per cubic meter.1-1. Use 9 tons of heavy bricks, you can save 80% of refractory insulation materials.

4. Energy saving: Alumina hollow balls have obvious thermal insulation characteristics and low thermal conductivity, which can play a good thermal insulation effect, reduce heat dissipation, and improve thermal efficiency, so as to achieve the purpose of energy saving. The energy saving effect can reach more than 30%.

It can be used for high temperature and energy-saving (>30%) inverted flame kiln. Shuttle kiln. Molybdenum wire furnace. Tungsten rod furnace. Induction furnace. nitriding furnaces, etc.
