Alumina hollow ball brick application

The refractoriness of alumina hollow ball bricks can reach over 1750°C, with good thermal stability, a small change rate of the burning line, and durability. It has strong thermal insulation properties and low thermal conductivity. Alumina hollow ball bricks can be used in high-temperature energy-saving inverted flame kilns, tempat pembakaran antar-jemput, tungku kawat molibdenum, tungku batang tungsten, tungku induksi, nitriding furnaces, dll..

Characteristics of alumina hollow ball bricks

1. High-temperature use: stabilitas termal yang baik, hingga 1750 degrees or above. The change rate of the reburning line is small and the use time is long.
2. Optimalkan struktur dan kurangi berat tungku: At present, high-temperature resistant materials are heavy bricks with a volume density of 2.6-3.0g/cm. Alumina hollow ball bricks only have 1.1~1.5g/cm, and the same one cubic meter m volume, using alumina hollow ball bricks can reduce the weight by 1.1-1.9 tons.
3. Hemat bahan: In order to achieve the same operating temperature, jika batu bata berat digunakan, the price is equivalent to the price of alumina hollow ball bricks, but a large amount of insulating refractory materials is also required. If you use alumina hollow ball bricks, you can save 1.1-1 per cubic meter. If you use 9 tons of heavy bricks, you can save 80% of refractory insulation materials.
4. Hemat energi: Bola berongga alumina memiliki sifat insulasi termal yang jelas dan konduktivitas termal yang rendah. They can play a good thermal insulation role, mengurangi pembuangan panas, dan meningkatkan efisiensi termal, thereby achieving the purpose of energy saving.
