CALGAS 1100 is a rotary degassing system suspended via an overhead hoist or a fork lift.
A metered amount of inert gas is injected into the molten aluminium through a rotating graphite shaft and rotor assembly. The rotor shears the inert gas into tiny bubbles and disperses them evenly throughout the melt. Unwanted hydrogen gas and non-metallic inclusions are attached to the inert gas bubbles and rise to the surface.
Advantages
-
Improves casting quality by reducing oxides and hydrogen
-
Reduces the loss of aluminium in the dross removal process
-
Reduces oxide buildup on furnace walls
-
Reduces loss of flux through furnace emissions
-
Efficiently uses nitrogen or argon inert gas
