Title: Vacuum heating furnace and vacuum heating method
Inventor: INUZUKA SHINOBU
IPC: F27D7/06
Filed: 1991-08-27
Abstract: PURPOSE:To prevent the generation of preclusion against the increasing of the degree of vacuum due to the evaporation of adhered water by a method wherein the adhesion of water to the internal surface of a furnace shell due to the condensation of water vapor is prevented by keeping the temperature of the furnace shell through a temperature keeping means when the furnace shell is evacuated and a work to be treated is heated. CONSTITUTION:A vacuum device 17 is operated and the inside of a furnace shell 2 is evacuated while a heater 12 is excited and the heating of a work 31 to be treated is started. Heat medium, such as hot-water or the like, is conducted through a water-cooled jacket, for example, as the temperature keeping means for the furnace shell 2, which keeps the furnace shell at a predetermined temperature, whereby the internal surface of the furnace shell is retained at a temperature precluding the condensation of water vapor even when the water vapor, generated from the work 31 to be treated, has arrived at the vicinity of the same. According to this method, water vapor, evaporated from the work 31 in accordance with the heating of the same, is discharged out of the furnace shell 2 through a discharging pipeline 18 without being condensed whereby the water vapor is removed as condensed water by a condenser 19 before arriving at the vacuum device 17. Accordingly, moisture will never arrive at the vacuum device 17 and the deterioration of the vacuum device 11 can be prevented.
