【考案の詳細な説明】
この考案は、黒体炉として用いられるような球
形炉に関するものである。[Detailed description of the invention] This invention relates to a spherical furnace used as a blackbody furnace.
一般に放射温度計の検定，目盛校正に用いられ
る精密黒体炉として管状炉の他に特願昭53−
131180の第１図で示されるように炉体に加熱体を
巻いて固定台に置いたものがある。これであると
固定台より熱が熱伝導により逃げてしまい均一温
度とするのはむずかしい。この改良のため炉体を
棒状支持部材により浮かして固定する方法が提案
されているが、これでは炉体を安定して固定する
ことがむずかしく製造が非常に困難であつた。 In addition to the tube furnace, the precision blackbody furnace is generally used for the verification and scale calibration of radiation thermometers.
As shown in Figure 1 of 131180, there is a furnace with a heating element wrapped around it and placed on a fixed stand. In this case, heat escapes from the fixed table through thermal conduction, making it difficult to maintain a uniform temperature. To improve this, a method has been proposed in which the furnace body is floated and fixed using a rod-shaped support member, but this method makes it difficult to stably fix the furnace body and is extremely difficult to manufacture.
この考案の目的は、以上の点に鑑み、炉体を確
実に固定できる球形炉を提供することである。 In view of the above points, the purpose of this invention is to provide a spherical furnace in which the furnace body can be securely fixed.
第１図は、この発明の一実施例を示す構成説明

体１を収納するレンガ等の保温材からなる箱体、
３は箱体２の内部にて炉体１を固定するために炉

ための炉体１の開口部である。 FIG. 1 is a configuration explanatory diagram showing one embodiment of the present invention, in which 1 is a spherical furnace body with a hollow interior, 2 is a box made of a heat insulating material such as a brick, which houses the furnace body 1;
3 is a cylindrical support member provided at the bottom and top of the furnace body 1 to fix the furnace body 1 inside the box body 2; 5 is a thermometer such as a thermocouple for measuring the furnace temperature, and 1a is an opening in the furnace body 1 for calibrating the radiation thermometer to be calibrated.
このような構成の球形炉では、まず、箱体２の
内部に設けられた加熱体４を通電発熱させ、この
加熱体４の熱により球形の炉体１を関接加熱す

り、炉体１と箱体２との間は空洞放射により均熱
となつているとともに、炉体１は円筒状の支持部
材３により安定に浮かして固定され、炉体１はほ
とんど均一の温度とされる。従つて炉体１の内部
は極めて理想的な黒体条件となり、開口部１ａよ
り被校正用放射温度計で炉体１内部をねらい、温
度計５にて炉温を測定することにより、放射温度
計の校正を行うことができる。 In the spherical furnace having such a configuration, first, the heating body 4 provided inside the box body 2 is energized to generate heat, and the spherical furnace body 1 is indirectly heated by the heat of the heating body 4. At this time, the inside of the box body 2 is sealed, and the space between the furnace body 1 and the box body 2 is uniformly heated by cavity radiation, and the furnace body 1 is stabilized by the cylindrical support member 3. The temperature of the furnace body 1 is almost uniform. Therefore, the interior of the furnace body 1 has extremely ideal blackbody conditions, and the radiation temperature can be determined by aiming the radiation thermometer to be calibrated inside the furnace body 1 through the opening 1a and measuring the furnace temperature with the thermometer 5. The meter can be calibrated.
又、第２図イで示すように円筒状の支持部材３
として側面に開孔３ａを設けるようにすると、箱
体２内部での空洞放射は増進され、均熱効果がい
つそう向上する。又、第２図ロで示すように円筒
状の支持部材３のかわりに、開孔６ａを有する箱
状の支持部材６を用いても同等の効果がえられ
る。 In addition, as shown in FIG. 2A, a cylindrical support member 3
By providing an opening 3a on the side surface, the cavity radiation inside the box body 2 is enhanced, and the heat uniformity effect is greatly improved. Further, as shown in FIG. 2B, the same effect can be obtained by using a box-shaped support member 6 having an opening 6a instead of the cylindrical support member 3.
又、第２図ハのように井げた状の支持部材７、
第２図ニのように開孔８ａを有する板状の支持部
材８により炉体１を支持するようにしてもよい。 In addition, as shown in FIG. 2C, a protruding support member 7,
The furnace body 1 may be supported by a plate-shaped support member 8 having an opening 8a as shown in FIG. 2D.
以上述べたように、この考案は球形の炉体を筒
状支持部材により支持するようにした球形炉であ
る。 As described above, this invention is a spherical furnace in which a spherical furnace body is supported by a cylindrical support member.
従つて、固定台を用いていないので炉体を軽く
することができ、又、棒状支持部材よりも安定に
炉体を支持でき、しかも空洞放射により炉体は均
熱とされ炉体内部は理想的な黒体条件となり、精
密黒体炉として好適である。なお、筒状支持部材
の側面に開孔を設けると均熱効果はいつそう向上
させることができる。又、支持部材を炉体の下部
のみならず上部および下部に設けるようにすれ
ば、更に安定性は向上する。 Therefore, since no fixed stand is used, the furnace body can be made lighter, and the furnace body can be supported more stably than a rod-shaped support member.Moreover, the furnace body is uniformly heated by cavity radiation, and the interior of the furnace body is ideal. This results in a blackbody condition suitable for a precision blackbody furnace. Note that if openings are provided on the side surface of the cylindrical support member, the heat uniformity effect can be greatly improved. Moreover, if the supporting members are provided not only at the lower part of the furnace body but also at the upper and lower parts, the stability will be further improved.
