Product Description

Low Creep High Alumina Brick for Hot-blast Stove

Characteristics:

1: The content of AL2O3 is ≥50%.

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 alkali slag corrosion.

Application:

The main markets for low creep high alumina brick are building lining of hot-blast stove, blast furnace, rotary kilns of cement and so on.
