Introduction of High Purity Corundum Refractory Brick For Industrial Furnace And Kiln

Corundum Brick is a kind of refractory product with corundum as the main crystal phase and contains over 90% aluminium oxide content. Corundum fire bricks have very high cold crushing strength that can reach up to 340MPa and high apparent initial softening temperature that is over 1700℃. Corundum refractory brick can be used in blast furnace, hot blast stove, glass furnace and etc.

Properties of High Purity Corundum Brick

* High temperature resistance;
* High compression strength;
* High dense structure;
* Good thermal shock resistance;
* Strong resistance to acid and alkaline slag erosion;
* Good chemical stability;
* Good resistance to metal and glass liquid;
