This pressure door 11
The structure is such that the object to be processed 50 inserted through the holder is heated by a built-in heater 40 in a vacuum atmosphere. A heat insulating wall 13 is provided on the inner wall of the furnace shell 10 so as to surround a total of six heaters 40. A heat insulating wall on the back side of the pressure door 11 is fixed to the pressure door 11 as a heat insulating wall 14. This insulation wall 1
4 is provided with an opening 141 at a position where the object to be treated 50 is viewed, and the furnace shell 1 is connected to the pressure door 11.
An O-ring 15 is provided on the furnace shell 10 to maintain a sealed state.

A rotary plate 20 having an observation window 30 for observing the heat treatment state of the rotary plate 20 is rotatably provided, and a circular heat insulating material 21 (insulating wall 13 , made of the same material as the heat insulating wall 14) are fixed with their axes aligned. Further, an opening 211 is provided at an eccentric position of the heat insulating material 21 for extracting light from the object to be processed 50 through the opening 141.
An opening 221 is opened at a position corresponding to the opening 211 of 0. However, this opening 141 has an opening area that corresponds to the locus of movement of the opening 211 that rotates as the rotary plate 20 rotates.

トすることができるので有利である。 To explain in more detail, the pressure door 11 is provided with a presser ring member 12 that slidably presses down the peripheral end of the rotary plate 20, and the opening 2 of the rotary plate 20
A pipe member 22 having a protective glass 24 at its tip is provided at a position corresponding to 21. This protective glass 24 is fixed by a cap 23 attached to the tip of the cylindrical member 22. That is, the exposed portion of the protective glass 24 fixed to the cap 23 corresponds to the observation window 30. Note that 16 is an O-ring provided on the pressure door 11 for the rotating plate 20. In other words, the light from the object to be processed 50 is transmitted through the opening 141 of the heat insulating wall 14,
Opening 211 of the heat insulating material 21, opening 221 of the rotating plate,
It is taken out sequentially through the inside of the pipe member 22 and the protective glass 24. Furthermore, light can be blocked by closing the shutter 25 provided on the pipe member 22. Although this shutter 25 is not necessarily provided, it is advantageous because it can shut out some of the heat escaping through the observation window 30.

The heat treatment state of No. 0 can be monitored through the observation window 30, and when the rotary plate 20 is further gradually rotated, the observation field of the object to be processed 50 changes. This means that when the rotating plate 20 is rotated once, the opening area of the observation window 30 is expanded to be equal to the area of the rotating plate 20. However, since the opening 211 formed in the heat insulating material 21 on the back side of the rotary plate 20 has an area corresponding to the observation window 30, the heat escaping through the opening 211 is the same as in the conventional case. Moreover, if the shutter 25 is closed, the heat shielding effect will be further enhanced.

なお、本考案にかかる熱処理炉は、真空焼結炉

板の取付箇所についても限定されることはない。 Note that the heat treatment furnace according to the present invention is of course applicable to heat treatment furnaces other than vacuum sintering furnaces, and there are also limitations regarding the rotation mechanism of the rotary plate having an observation window and the mounting location of the rotary plate. It never happens.

行う上でも非常に大きなメリツトを有する。Effects of the invention As described above, in the case of the heat treatment furnace of the present invention, the observation window placed at an eccentric position on the rotary plate rotates and is provided with heat insulating material except for the observation window. This means that the observation field of the object to be processed can be expanded without increasing heat loss from the shell. In other words, it is possible to accurately grasp the heat treatment state of the object to be treated while saving energy, and it also has a great advantage in performing more precise temperature control.
