High Grade Bauxite Al2O3 48% High Alumina Refractory Bricks


Definition:

High Alumina Andalusite Fused Mullite Refractory Bricks is a kind of refractory material. The main component of this refractory brick is Al2O3.


Due to different resources, national standards are not completely consistent. For example, European countries stipulate that the lower limit of Al2O3 content for high aluminum refractory is 42%.


In China, the Al2O3 content in high-alumina bricks is usually divided into three grades: Ⅰ etc.-Al2O3 content> 75%; Ⅱ etc.-Al2O3 content is 60 ~ 75%; III etc.-Al2O3 content is 48 ~ 60%.


Low Creep High Alumina Refractory Bricks is a neutral refractory with alumina content above 48%.


It is formed by calcining alumina and other raw materials with high alumina content. High thermal stability, fire resistance above 1770℃. It has good slag resistance and is used for lining steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc.


High-load soft, low-creep high-alumina brick is a high-grade refractory material made of super-grade alumina, fused corundum, and fused mullite as the main raw materials.


Advantage:


Competitive Price. Make the products competitive in your market.

Abundant Experience. Prevent cracks and twist in bricks.

Different Moulds. Save mould fees for you.

Strict Quality Control.

Meet clients’ quality requirement.

Large stocks. prompt delivery.


Application:

High Alumina Andalusite Fused Mullite Refractory Bricks mainly used for the insulating lining of hot surfaces or backing heat-insulating layers of other
refractory materials. The refractory linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, ubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc.
