Product Description
Corundum brick
Characters of Corundum brick
Corundum brick is a kind of refractory products made of Al2O3 content more than 90%,with corundum as primary crystalline phase. It has very high compressive strength (up to 340 MPa). High RUL (more than 1700 ºC). Good chemical stability against acid or alkaline slag, metal and glass, etc. Corundum brick can be divided into two kinds: sintering corundum brick and fused corundum brick two kinds.
Applications of Corundum brick
It is mainly used for blast furnace and blast furnace hot blast stove, furnace refining furnace, sliding water apparatus, glass furnace, and petrochemical industrial furnaces, etc.
