High Alumina Refractory Bricks

Descriptions:
High-alumina bricks are made from bauxite, a naturally occurring material containing aluminum hydroxide (al[oh]3) and kaolinitic clays. These raw materials are roasted to produce a mixture of synthetic alumina and mullite.
By definition high-alumina bricks contain between 60 and 95 percent alumina and much more robust than fireclay refractories at high temperatures and in basic environments.
In addition, these bricks exhibit better volume stability and abrasion resistance.

Applications:
High-alumina bricks are used in blast furnaces, blast-furnace stoves, liquid-steel ladles, steel refining furnaces, glass tanks, ceramic kilns, enamel kilns, rotary cement kilns and other vVarious kilns and furnaces.
