  Refining carried out in Ingot degassing unit

  Spinning Nozzle Inert Flotation (SNIF) – inert gasoline flotation thru a rotating purge device. the primary components of the SNIF P140UНВ secondary Ingot Degassing machine.

  the main components of the setup of the degassing unit

  SNIF installation works on the principle of blowing system gasoline, generally argon, through rotating graphite devices, the variety of which may be from one to 4, depending on the layout and setup.

  The rotation of the purge assembly at the side of continuous delivery of argon creates a massive wide variety of fuel bubbles that are absolutely distributed within the volume of the aluminum soften, thereby growing a “reactor with precise mixing.” when argon bubbles glide, the hydrogen dissolved in aluminum is desorbed into growing bubbles and removed from the melt.

  when a small amount of chlorine (generally less than 0.5% of the method gasoline glide) is delivered to the system gas, non-wettable non-metallic inclusions are separated from aluminum, connected to a degassing unit, and glide to the floor. Chlorine also reacts with dissolved alkali metals (Na, Li, Ca, and ok) to form chlorides that go with the flow to the surface and pass into slag. The Na content inside the 5xxx series within the AMg3do “SNIF” alloy is zero.0006%, after zero.0003% – zero.0002%, this is the Na content decreases by 2 or greater times. Non-metallic particles and salts are then eliminated from the SNIF system.
