Abstract
Apparatus for melting, holding and tapping metals or metal alloys, in which solid material is melted down in a channel-type induction furnace, the melt then being transferred to a second channel-type induction furnace to be kept hot, possibly over-heated and stored, characterized in that the melting furnace is connected to the second furnace by way of a feeding channel and is located at a higher level than the second furnace and that the second furnace is in the form of a pressure furnace for pressure tapping through a spout. As a further characterizing feature, the tapping spout is provided with a tun dish in which sub-atmospheric pressures can be obtained to control the tapping through the spout.
