Product description
Corundum bricks refer to refractory products with an alumina content greater than 90% and corundum as the main crystal phase. Very high normal temperature compressive strength (up to 340MPa). High load softening onset temperature (greater than 1700°C). It has good chemical stability and strong resistance to acidic or alkaline slag, metal and glass liquid. Thermal shock stability is related to its organizational structure, and dense products have good corrosion resistance.
Application
CH Refractories manufacturing corundum brick has widely application including:
◆Hot Blast Stove
◆Refining Furnace
◆Glass Furnace and blast Furnace
◆Petrochemical Industrial Furnaces
◆All kinds of high temperature kiln lining in metallurgical industry
Advantages of CH Refractories corundum brick
◆High annual output
◆Free size design, free mould chagres
◆Good thermal shock resistance
◆Competitive price
◆Strict raw material and manufacturing process control
