Abstract (en)
[origin: US6460604B1] An apparatus for uphill low pressure casting of molten metal in sand molds conveyed in synchronized manner with a casting station located at the conveyor, a gas pressure holding furnace containing the molten metal and located at the casting station with a rising casting tube connectable to the sand molds has a device for refilling the holding furnace with molten metal. To permit a rapid casting cycle and high casting capacities, the refilling device has at least one pressure-tight melt container and a filling tube located in the holding furnace with a seal positioned outside the same. The melt container is couplable in pressure-tight manner by means of its outlet to the holding furnace filling tube. The holding furnace is connected to the melt container by means of a pneumatic pressure compensating line.
