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, hornos lanzadera, hornos de alambre de molibdeno, hornos de varilla de tungsteno, hornos de inducción, nitriding furnaces, etc..

Characteristics of alumina hollow ball bricks

High-temperature use: buena estabilidad térmica, hasta 1750 degrees or above. The change rate of the reburning line is small and the use time is long.
Optimizar la estructura y reducir el peso del horno.: Actualmente, 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.
Guardar materiales: In order to achieve the same operating temperature, si se utilizan ladrillos pesados, 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.
El ahorro de energía: Las bolas huecas de alúmina tienen propiedades obvias de aislamiento térmico y baja conductividad térmica.. They can play a good thermal insulation role, reducir la disipación de calor, y mejorar la eficiencia térmica, thereby achieving the purpose of energy saving.
