Graphite in gas flushing treatments of aluminum melts

When casting aluminium melts, significant improvements in the quality of the castings can be achieved by gas flushing treatments. Gas injection tubes, gas distribution systems, and degassing tubes made of graphite are particularly well suited for this purpose, as the graphite proves resistant to the flushing gases utilized, namely chlorine, nitrogen and argon as well as their mixtures and further aggregates.
