ABSTRACT OF THE DISCLOSURE A semicontinuous casting apparatus comprises a holding furnace connected through a closed metal feeding system to a metal supply means having a metal supply duct. Mounted on the metal supply means is a mould provided with a cooling system and having a dummy bar placed in its upper part and connected with a casting withdrawal system. The mould cooling system is provided with a device for forcing out a liquid coolant from the mould by means of compressed gas. The dummy bar has a central head which accom- modates a heating element and an adjustable valve for admitting an inert gas into the casting being formed. The casting withdrawal system has two casting withdrawal mechanisms alternately co- operating with the dummy bar and of which one is used for pulling out the casting from the mould for a distance not smaller than the length of the casting minus the length of the mould, and the other one is effective to pull out the casting from the mould for a distance not smaller than the length of the mould. The invention is preferably utilized in the production of solid and hollow castings by a semicontinuous casting process in which such castings are drawn up from a mould.
