Aluminum Siphon Tubes‌

Essential components for all types of ladles (open-top and vacuum ladles) in aluminum smelting operations

‌Working Principle：‌

• ‌● Immersed into molten aluminum (1,300–1,400°C) within electrolytic cells

• ‌● Utilizes ‌siphon effect‌ to transfer molten aluminum into ladles

Must withstand:

• ‌● Extreme thermal shock (repeated heating/cooling cycles)

• ‌● Corrosive fluoride electrolytes

• ‌● High-velocity erosion from molten metal

• 
  

‌Material & Construction：‌

● Two-Part Integrated Design:‌

1. ‌Upper Section:‌ Carbon steel pipe

2. ‌Lower Section:‌ Hard alloy overlay pipe

   Fabricated via ‌hardfacing welding‌ (D802, YD856, or equivalent hard alloy electrodes)

‌● ‌Critical feature:‌ Length exceeds electrolytic cell height for full immersion

‌Performance Requirements：

✔ ‌Oxidation Resistance:‌ Prevents scaling in molten aluminum

✔ ‌Heat Resistance:‌ Stable at 1,400°C

✔ ‌Thermal Fatigue Resilience:‌ Endures rapid temperature cycling

✔ ‌Erosion/Chemical Resistance:‌ Withstands molten metal & electrolyte corrosion

Key Advantages：‌

• ‌Robust Welding:‌ Seamless carbon steel/hard alloy joint ensures structural integrity

• ‌Customizable:‌ Hardfacing materials adaptable to specific operational conditions

Note: Available for both standard and vacuum ladle configurations.
