Corundum Bricks for Flash Furnaces

Are you still struggling to decide on the appropriate corundum content for your flash furnace?

Rear Half of the Rising Flue

Short-term temperature fluctuations of 800–1450℃, large temperature differences, and frequent thermal shocks; the main components of the acidic sulfur-based flue gas are SO₂ and SO₃. It is extremely corrosive to alkaline refractory materials at high temperatures, but has excellent inertness to Al₂O₃ corundum, which is the core reason for choosing corundum bricks.

Waste Heat Boiler Lining

Recovering waste heat from high-temperature flue gas to generate steam for power generation, cooling flue gas, and settling coarse dust, with no molten copper matte splashing throughout the process. It is the primary application area for corundum bricks.

98 High-purity sintered corundum bricks and low-zirconium corundum bricks can block alkali metal penetration with extremely low porosity and resist high-speed dust abrasion with ultra-high strength.

Operational Life Extension Measures

Stable system continuous production, reducing frequent start-ups and shutdowns, and minimizing thermal shock damage;

Strictly control potassium and sodium impurities in the feed concentrate to reduce alkali metal corrosion from the source;

Regularly vibrate and clean the boiler to prevent ash accumulation, pipe blockage, and localized overheating.
