Brief: Watch this overview to discover why many professionals pay attention to this approach. Learn how industrial-grade aluminium refine flux enhances high degassing efficiency and hydrogen removal in molten aluminium, ensuring superior casting quality.
Related Product Features:
  • Industrial-grade aluminium refine flux effectively removes dissolved hydrogen gas and non-metallic inclusions from molten aluminium.
  • Acts as a 'detergent' or 'purifier' for molten aluminium, improving mechanical properties and pressure tightness.
  • Prevents porosity and inclusions by reducing surface tension and agglomerating oxide particles.
  • Available in various types including covering, cleaning/refining, degassing, and wall-cleaning fluxes.
  • Common components include NaCl, KCl, Na₂SiF₆, Na₃AlF₆ (Cryolite), C₂Cl₆, MgCl₂, and MnCl₂.
  • Best applied via rotor injection, plunging (bell method), or simple addition depending on scale.
  • Requires proper skimming of dirty flux slag post-application to avoid re-contamination.
  • Critical safety measures include adequate ventilation and PPE due to toxic and corrosive fumes.
Faqs:
  • What is the primary purpose of aluminium refine flux?
    The primary purpose is to remove dissolved hydrogen gas and non-metallic inclusions like oxides, carbides, and nitrides from molten aluminium, ensuring higher quality castings.
  • How does aluminium refine flux work?
    It works through chemical reactions that degas the molten aluminium and physical actions that reduce surface tension, allowing oxide inclusions to agglomerate and float to the surface for removal.
  • What safety precautions should be taken when using aluminium refine flux?
    Always use adequate fume extraction and ventilation, wear appropriate PPE including a respirator, face shield, gloves, and apron, and ensure the flux is dry to prevent steam explosions.
