ABSTRACT:
A plunger charged as an electrode is received in a trough charged as a counter-electrode in order to heat material in the trough above the annealing temperature of metal material or the sintering temperature of ceramic-material. The trough and plunger are situated in a vacuum chamber separated from a condenser and pump stand by a valve. The plunger can be retracted into a cover of the chamber by a hydraulic drive on the cover. The cover, drive, and plunger are removable from the lower part of the chamber as a unit.
