Product detais
A refractory product having a alumina content of more than 90% and a corundum-based crystal phase. Very high room temperature compressive strength (up to 340MPa). High load softening onset temperature (greater than 1700 ° C). Very good chemical stability, strong resistance to acidic or alkaline slag, metal and glass. The thermal shock stability is related to its structure, and the corrosion resistance of the compact product is good, but the thermal shock stability is poor.

The thermal shock stability is related to its structure, and the corrosion resistance of the compact product is good, but the thermal shock stability is poor. Divided into sintered corundum brick and fused corundum brick. Sintered alumina and fused corundum can be used as raw materials or alumina clinker with high Al2O3/SiO2 ratio and sintered alumina can be prepared by sintering method. Phosphorus or other binders can also be used to make unfired corundum bricks. Mainly used in ironmaking blast furnace and blast furnace hot blast stove, steelmaking furnace outside refining furnace, sliding water, glass melting furnace and petrochemical industrial furnace.
Widely used in the cracking, reforming furnace, metallurgical industry and other high-temperature kiln linings and kiln furniture in the petrochemical and fertilizer industries.
