Low creep high alumina brick for Hot Blast Stove

Low creep high alumina brick is made of corundum, mullite “sillimanite, andalusite and kyanite” and high-quality bauxite clinker as raw material by shaping at high pressure and sintering at high temperature.

Low creep high alumina brick characteristic:

1. The content of AL2O3 is ≥48%.
2. High refractoriness. The temperature is up to 1750~1790oC, it belongs to high-duty refractory.
3. 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.
4. 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.

Low creep high alumina brick application:

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