Vacuum heating furnace “PVV-1300”

Appointment


Vacuum heating furnace “PVV-1300” is made of two chambers, located one above the other. It is designed to homogenize parts and discs made of heat-resistant alloys, as well as hardening, brazing, tempering and annealing after thermal treatment.
Furnace heats a workpiece in a vacuum to a certain temperature, hold it at this temperature, move into the lower chamber and cool in inert gas medium.
