Melting and casting process and combined melting and casting furnace plant

Process for melting metal parts and casting a molten metal from melting the metal parts into at least one mould for receiving the molten metal, comprising the following steps:

• a. placing the metal parts in a crucible furnace with a device for bringing the metal parts to be melted into the crucible furnace;
• b. producing the molten metal and making the molten metal ready for casting in the crucible furnace;
• c. heating a riser tube, with a heating device, arranged on a pressure-tight crucible furnace lid of the crucible furnace, which forms a unit with the crucible furnace lid, at a position remote from the crucible furnace;
• d. moving, with a lifting and traversing device, the lid with the heated riser tube to a position closing the crucible furnace, in which position the riser tube projects into the molten metal;
• e. moving the at least one mould to a casting position on the lid and above the riser tube with a device for bringing the at least one mould into the casting position on the crucible furnace;
• and
• f. pouring, with a device for pouring the produced molten metal, the molten metal through the riser tube from below into the at least one mould by pressurising the molten metal in the crucible furnace and feeding the molten metal into the at least one mould.
