FAQ
Advantages
① Corundum‑based refractory bricks feature great high‑temperature tolerance and excellent resistance against molten aluminum corrosion. Operating persistently above 750 °C, the furnace lining can serve 12‑18 months, significantly outperforming fiber linings which only last 3‑6 months.
② It delivers decent anti‑corrosion and thermal‑shock resistance. Under frequent material charging and discontinuous production modes, lining spalling and aluminum leakage rarely occur.
③ Boasting prominent heat‑retaining performance, the lining cools down slowly after shutdown, which cuts energy loss for non‑stop production runs.
④ For localized lining damage, operators only need to swap defective single bricks instead of reconstructing the whole lining, bringing down maintenance expenses effectively.
Drawbacks
This furnace comes with substantial dead weight, which calls for reinforcement on plant building foundations. It demands a lengthy drying period of 3‑5 days. Its upfront masonry investment exceeds that of full‑fiber furnaces, and heat‑up speed is moderately limited. This solution fits high‑tonnage aluminum melting furnaces with large recycled‑material input and long‑term 24‑hour continuous casting production lines.
