Remeltingan overview ScienceDirect Topics
A variant of the VAR process called skull melting is widely used for casting Ti and other reactive metals. In this case the water-cooled Cu crucible has a tilt capability for pouring castings. The electrode is melted at a very high rate and after the crucible is filled with metal it is immediately tilted to pour the metal into a mold.
