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.
High compressive strength
Good thermal shock resistance
Resistant to acid and alkali corrosion
Chrome corundum bricks are widely used in petrochemical industry gasifiers such as glass kiln lining, brushed glass flow hole cover bricks, hot metal pre-treatment devices, garbage incinerators, coal water slurry pressurized gasifier backing, zinc smelting electric furnaces, carbon black furnaces, copper smelting furnaces, steel push type metallurgical furnaces, volatilization kilns, and taphole.
Chrome corundum bricks can also be used in industrial equipment with high temperature, high pressure, and strong corrosiveness.
