Abstract
A vacuum furnace adapted to cool a load. The vacuum furnace has one or more means for cooling a fluid and a muffle substantially containing the load. The fluid flows in a substantially unidirectional flow substantially within the muffle.
Claims17
A vacuum furnace adapted to cool a load comprising:
- an insulated hot zone shell located within a vacuum chamber;
- a muffle located within the hot zone shell, the muffle having opposing open ends and substantially containing the load, the muffle comprised substantially of lanthanum doped molybdenum;
- one or more heating means within the hot zone shell and substantially surrounding an exterior portion of the muffle;
- a pair of doors located at each of the opposing open ends of the muffle, and
- a pair of end caps substantially in contact with each of the doors.
2 more elements
A vacuum furnace for heating a load comprising:
- one or more means for heating the load;
- and
- a generally corrugated muffle substantially containing the load, the muffle comprised substantially of lanthanum doped molybdenum,
- wherein the one or more means for heating the load is substantially external to the muffle and a pressure interior to the muffle and a pressure exterior to the muffle are substantially similar.
