STAR™ Rotor Features
In spinning-rotor degassing/fluxing systems, a metered amount of inert gas or flux is injected into the molten aluminium, through a rotating graphite shaft and 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.
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 flux, and nitrogen or argon inert gas
Overcomes problems associated with traditional powder fluxes
