Chrome corundum Bricks is produced with high quality of sintered corundum, synthetic mullite and chromium oxide as raw material and processed under high temperature and high pressure. They have high bulk density, high compressive strength, good thermal shock resistance, good corrosion resistance to acid and alkali. The bricks are not affected by H2, CO gase.
It can be used as lining of glass kiln, brushed glass flow hole cover brick and backing of molten iron pretreatment device, garbage incinerator, coal water slurry pressurized gasifier, etc.
