Patent ID: 11524333

Abstract:
A process for melting metal parts and casting the melt in at least one mould and a corresponding combined melting and casting furnace plant are described. In the process, metal parts to be melted are brought into a crucible furnace, and a molten metal is produced therein and made ready for casting. A riser tube integrated in a lid of the crucible furnace is heated in a position remote from the crucible furnace, and the lid with heated riser tube is brought into a position closing the crucible furnace, in which the riser tube projects into the molten metal. A mould is arranged on the lid in a casting position above the riser tube, and the molten metal is introduced into the mould from below by pressurising the melt in the crucible furnace. The combined melting and casting furnace plant is designed to carry out such a process.
