PURPOSE:To carry out heat treatment continuously while objects to be treated are carried in and out without disturbance of the atmosphere in the main chamber by a method wherein the inlet and outlet of the main chamber for heat treatment are provided with reserve chambers, and an operable partition plate is provided between each chamber. CONSTITUTION:The first partition plate 10 is opened, and then an object 7 to be treated is introduced to the first reserve chamber 8 by means of a carry-in part 5. Next, the partition 10 is closed, the atmospheric gas in the chamber 1 being introduced to the chamber 8 through a vent 14 provided in the second partition 11, and the gas present in the chamber 8 being then exhausted through an exhaust port 16. The partition 11 is opened, and then the object 7 in the chamber 8 is introduced to the chamber 1 by means of a carrier system 4. Successively, the partition 11 plate is closed, and the next object 7 is introduced by opening the partition plate 10. Continuous heat treatment is carried out by repetition of this operation. |
