Hycast - SIR

Inline melt refining

State of the art degassing

The drain-free Hycast I-60/I-25 Siphon Inert Reactor (SIR) in-line filter system is the benchmark for refining, degassing and particle removal of molten aluminium in-line between the furnace and casting machine. This technology has been in operation since its introduction in 2001 and is throughly tested and verified in operation.

Technical features:

  • Unique melt refining concept with elevated metal above launder through underpressure
  • Bottom-mounted rotor system
  • Excellent removal of Hydrogen and inclusions
  • No mechanical filtration system required downstream for extrusion ingot lines
  • Exceptionally low dross generation due to reactor inert atmosphere
  • Low operational cost due to few rotors - gas usage only when in operation
  • Easy maintenance and no complex hydraulics
  • Available with or without chlorine

Design features:

  • Small footprint and easy to adapt to existing casting lines
  • Few components and short installation time
  • Sloped reactor bottom to drain metal into launder after casting
  • Electrical preheating system with hot air (no preheating needed between casts during normal operation)
  • Precast monolithic refractory lining with short relining times
  • Two standard designs for all flow rates, I-25 and I-60

I-25 SIR

  • I-25 SIR for metal flow rates up to 25mt/hour
  • Unique design with one bottom-mounted rotor
  • Elevated metal level inside reactor to achieve excellent removal efficiency
  • 100% inert reactor
  • 100% drain free reactor
  • Fully automated
  • Suitable for all alloy series
