Product Description

Good Wear Resistance Performance High Alumina Corundum Brick

Product Description

Refractory Corundum Brick Introduce

Corundum brick is alumina content more than 90%, with corundum as the main crystalline phase of refractory products. Corundum bricks have very high compressive strength at room temperature (up to 340MPa) and high initial softening temperature under load (greater than 1700ºC). Good chemical stability, acid or alkaline slag, metal and liquid glass have strong resistance.

Application of Corundum Brick

Blast Furnace
Hot Blast Stove
Refining Furnace
Glass Furnace
Petrochemical Industrial Furnaces
All kinds of high temperature kiln lining in metallurgical industry
