How Pyrotek’s Rotary Degassing/Fluxing Systems Work:
In spinning-rotor degassing/fluxing systems, a metered amount of inert gas or flux is injected into the molten aluminium, through the rotating graphite shaft and patented STAR rotor. The STAR rotor shears the inert gas into tiny bubbles and disperses them evenly throughout the melt. Unwanted hydrogen gas and non-metallic inclusions are attracted to the inert gas bubbles and rise to the surface. The flux injection allows a steady flow of flux below the metal line which promotes oxide entrapment.

The combined effect of gas injection and fluxing helps improve the quality of aluminium alloys and reduces operating costs.
