Product Description

Composite Refractory Material Corundum Fire Brick Corundum Mullite Refractory Brick For High Temperature Kilns

Product Description

Corundum Mullite Brick Introduce

Corundum bricks are refractory products with alumina content greater than 90% and corundum as the main crystal phase. High normal temperature compressive strength (up to 340MPa). High softening onset temperature under load (greater than 1700°C). Good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid. The thermal shock stability is related to its microstructure. The erosion resistance of dense products is good, but the thermal shock stability is poor. It is divided into sintered corundum bricks and fused corundum bricks. It can be made by using sintered alumina and fused corundum as raw materials respectively, or with bauxite clinker with high Al2O3/SiO2 ratio and sintered alumina. Unfired corundum bricks can also be made with phosphoric acid or other binders. Mainly used in iron-making blast furnaces and blast furnace hot blast furnaces, steel-making outside refining furnaces, sliding water heaters, glass melting furnaces and petrochemical industrial furnaces.
