To eliminate hydrogen and any impurity from the cast aluminum bath used to manufacture the industrial castings, ASEG GALLONI, together with an experienced customer has created an innovative system that combines an inert gas mixing device with vacuum.
When the aluminum/alloy loaded in the crucible has reached the molten state, two hollow graphite propellers are immersed in the bath, mixing the molten aluminum at a controllable speed and, since they are fitted with small holes, they blow inert gas at the same time. In this way, all the hydrogen and heavy scum present in the bath are made to rise to the surface. Once mixing has been completed the two propellers are extracted and vacuum casting is carried out. Thus scum remains trapped in the sprue which is subsequently cut while the alloy making up the piece is perfectly free of impurities and proposity.
