Metal melting process especially for melting titanium and its alloys in the production of dental castings

摘要

The metal melting process, uses thin bodies as the solid starting material, and a melting crucible. A crucible dividing line (23) extends centrally from the open top (12) of the crucible and then diverges as a sloping line or an arc towards an off-center bottom end (15) of the crucible. The crucible lower portion (14) tapers towards the bottom end (15) and is asymmetrical relative to the crucible center axis (16) or center plane (24). An Independent claim is also included for a melting crucible which is divided longitudinally along a dividing line (23) which is at least locally off-center.
