Features of Alumina Refractory Bricks

 

1. The content of AL2O3 is 65% - 75%.

2. High refractoriness under load. The RUL is higher than fireclay brick as the high content of Al2O3, however, it is lower than silica brick because of mullite crystal does not form reticular tissue.

3. Excellent slag resistance. High alumina brick is a kind of neutral refractory material so it enjoys excellent resistance to acid slag and alkali slag corrosion.

 

Application of Alumina Refractory Bricks

 

The high alumina bricks are widely applied to blast furnace,hot stove,electric stove,oven glass furnace and other thermal equipment.

 

Description of Alumina Refractory Bricks

 

1. Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
2. Al2O3 content is 75%,main mineral components are corundum and mullite phases.
3. Refractoriness is above 1770°C,refractoriness under load is 1420-1550°C.
4. Working temperature:1350°C -1650°C.
