Low creep high alumina brick for blast furnace 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.
1.The content of AL2O3 is ≥48%.
2.High refractoriness. The temperature is up to 1750~1790℃, it
belongs to High-duty Refractory.
3.High refractoriness under load. The URL 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.
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.
