Corundum brick classification, physical and chemical indicators and uses?
High load softening initial temperature (greater than 1700℃). Good chemical stability, strong resistance to acidic or alkaline slag, metal and liquid glass. The thermal shock stability is related to its structure. The corrosion resistance of dense products is good, but the thermal shock stability is poor.
Corundum brick is widely used in petrochemical and fertilizer industry cracking, conversion furnace, metallurgical industry and other high-temperature kiln lining, and kiln utensils.
