ABSTRACT:
A device for the discontinuous charging of molten metal into a vacuum chamber which is continuously held under vacuum includes a charging vessel or tundish on which is disposed a fixed transfer pipe so positioned that the tundish can be rotated about the axis of the pipe to such an extent that the pipe's input orifice is lifted above the surface of the metal flow in the tundish, while at the same time the pipe is withdrawn from the vacuum chamber. The chamber is sealed with a plate valve.
