Graphite For Degassing Shafts:-
Graphite Degassing Units are systems used for degassing hydrogen from molten aluminum. During the smelting process of aluminum, or aluminum alloys, hydrogen is produced through a chemical reaction with steam. Diffused throughout the aluminum, it creates voids, and ultimately cause structural defects. It will effectively weaken the casting. To combat this unwanted effect, most aluminum foundries will inject an inert gas, such as nitrogen or argon, which draws the hydrogen out from the aluminum / aluminum alloy.

The Graphite Degassing Units are assemblies of a graphite rotor and a graphite degassing tube (shaft). The rotor is designed and machined specifically to be capable of stirring uniformly the molted aluminum, and to disperse the gas. For that to happen, there is need for precision machining. The machining process, must strictly conform to customers drawing and tolerances. The rotor and the shaft must match perfectly, and the concentricity's must be high. These parameters are necessary to avoid creating unwanted disturbances throughout the molted material, as well as avoiding damage caused by mechanical stress.

Special treatment applied to the graphite components: An impregnation anti-oxidation treatment is usually applied to the system's components.
