Abstract
The disclosure relates to a device for producing an investment casting component, comprising a melting chamber having an induction coil assembly disposed in the melting chamber, wherein the induction coil assembly is adapted to melt off an electrode at least partially received therein to produce a ceramic-free continuous melt jet having a melt flow rate MFR of at least 2.5 kg/min. The device further comprises a casting chamber downstream of the melting chamber and connected thereto, with an investment casting mold received or receivable therein for being filled by means of the ceramic-free, continuous melt jet.
Claims20
A device for producing an investment casting component, comprising:
- a melting chamber comprising an induction coil assembly disposed in the melting chamber and adapted to melt off an electrode at least partially received therein to produce a ceramic-free continuous melt jet with a melt flow rate (MFR) of at least 2.5 kg/min;
- an electrode charger disposed upstream of the melting chamber and adapted to displace the electrode along its longitudinal axis in the direction of the induction coil assembly;
- and
- a casting chamber downstream of the melting chamber and connected thereto and comprising an investment casting mold received or receivable therein for being filled by means of the ceramics-free continuous melt jet.
A method for producing an investment casting component, comprising:
- providing an electrode in a melting chamber by an electrode charger disposed upstream of the melting chamber;
- inserting the electrode, at least in sections, into an induction coil assembly disposed in the melting chamber;
- generating a ceramic-free, continuous melt jet with a melt flow rate (MFR) of at least 2.5 kg/min by feeding the electrode with the electrode charger and melting off the electrode by means of the induction coil assembly;
- providing an investment casting mold in a casting chamber downstream of and connected to the melting chamber;
- and
- continuously filling the investment casting mold with the melt jet.
