Abstract
The present invention relates to a microwave melting apparatus and system for investment casting the metals obtained therefrom. In addition to enhanced production capacity, the system allows for the use of both a broad range of metal alloys and a variety of forms including ingot, scrap, granulated and powdered metals not possible with induction systems generally.
Claims18
A system for melting metals comprising:
- a tiltable furnace assembly including a housing and at least one microwave energy absorbing ceramic crucible disposed within said housing for heating metal contained therein to its melting temperature;
- a microwave energy source;
- at least one microwave guide assembly attached to said furnace housing for directing microwave energy at predetermined levels to said at least one microwave energy absorbing ceramic crucible wherein upon sufficient energy heating of the microwave energy absorbing crucible through the application microwaves, the metal disposed therein is melted;
- and
- a valve assembly extending from the bottom of the housing through which melted metal can be poured.
