The invention concerns a vacuum arc melting and casting furnace comprising a vacuum chamber, a tilting crucible and a current connection leading to the bottom of the tilting crucible. This current connection consists of a fixed contact and of a co-operating contact arranged on the bottom of the crucible and movable with the tilting crucible. Also provided is an electrode rod for holding an electrode concentrically in relation to the tilting crucible. The fixed contact is secured on at least two current conductors which are substantially coaxial with the electrode rod or electrode. These conductors pass through the vacuum chamber from the top and extend past the tilting crucible, and their distance apart is such that the crucible can be tilted between them into the casting position.
A vacuum arc melting and casting furnace with a vacuum chamber consisting of an upper part and a lower part, and with a tilting crucible and a non-breakable central current connection, which leads to the bottom of the tilting crucible and consists of a fixed contact and a co-operating contact which is arranged on the bottom of the crucible and is movable with the crucible, the furnace also having an electrode rod for holding an electrode concentric with the tilting crucible and for guiding the electrode, characterized in that the fixed contact (17) is secured to at least two rigid current conductors (13, 14), which are substantially coaxial with the electrode rod (11) and electrode (10) and extend downwardly through the vacuum chamber (1) and past the tilting crucible (9), and in that the current conductors are spaced from each other to such extent that the tilting crucible can be tilted between them into the casting position.
