Abstract
Apparatus for melting preferably highly reactive metals, such as titanium for example, in a vacuum melting furnace, for example a vacuum arc furnace for the remelting of metals, with one or more melting positions, a melting crucible (5, 28) being provided at each melting position, these crucibles being closed vacuum-tight after the end of the melting operation and then separated from the melting furnace, the furnace being provided with a single manipulator and by this manipulator each single crucible (5, 28) can be closed vacuum-tight by means of a separate crucible closure plate (13, 37).
Claims6
Apparatus for melting highly reactive metals, in a vacuum melting furnace, having a plurality of melting positions, comprising:
- a melting crucible provided at each melting position, these crucibles being closed vacuum-tight after the end of the melting operation and then being separated from the melting furnace, separate crucible closure plates, and a single manipulator and by this manipulator every crucible being closable vacuum-tight by means of one of said separate crucible closure plates.
