Abstract
Apparatus for casting metals, especially alloys with low melting points, has a melt container which is connected to a mold via a casting line. A standpipe branches off from the casting line in the melt container. The melt is covered by an inert fluid blanket and the level of melt in the melt container is monitored and maintained such that at least a portion of the standpipe is surrounded by the melt. An overflow valve selectively opens or closes an overflow hole in the standpipe, the overflow hole being immersed in the inert fluid, to adjust the level of melt in the casting line.
