この発明は、黒体炉として用いられる救形炉に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rescue furnace used as a blackbody furnace.
一般に放射温度計の検定、目盛校正等に用いられる黒体
炉としては管状炉の他に、球形炉が考えられる。In addition to tube furnaces, spherical furnaces can be considered as blackbody furnaces that are generally used for verification, scale calibration, etc. of radiation thermometers.
これは第１図で示されるように、内部が中空の球形の炉
体１と、この炉体１の表面に巻かれた加熱体２と、この
加熱体２の外部を絶縁する絶縁体３よりなり、適当な固
定台４にて固定されている。As shown in Figure 1, this consists of a spherical furnace body 1 with a hollow interior, a heating element 2 wound around the surface of this furnace body 1, and an insulator 3 that insulates the outside of this heating element 2. It is fixed with a suitable fixing base 4.
そして加熱体２に通電し，て発熱させ、炉体１を加熱し
、炉体１は球形対称形状なのでその内部は空洞放射によ
り均熱とされ、理想に近い黒体となる。Then, the heating element 2 is energized to generate heat, thereby heating the furnace body 1. Since the furnace body 1 has a spherically symmetrical shape, the inside thereof is uniformly heated by cavity radiation, and becomes an almost ideal black body.
従って炉体１に標準熱電対等の温度計５を挿入し、一端
開口部１ａより被校正用放射温度計６にてねらい放射温
度計の検定、目盛校正を行なっている。Therefore, a thermometer 5 such as a standard thermocouple is inserted into the furnace body 1, and the radiation thermometer to be calibrated 6 is used to verify and calibrate the scale of the radiation thermometer through the opening 1a at one end.
しかし，なから、球形の炉体１に均一に加熱体２をまく
のは非常にむずかしく、たとえ均一にまけても固定台４
を介して熱伝導により熱か逃げてしまうので、炉体１の
上部は高温となり、下部は低温となり、必ずし，も均一
な温度分布は得られず、精密な黒体炉とするのは非常に
むずかしかった。However, it is very difficult to evenly spread the heating elements 2 on the spherical furnace body 1, and even if it is evenly spread, the fixed base
As the heat escapes through heat conduction, the upper part of the furnace body 1 becomes high temperature and the lower part becomes low temperature, and it is not always possible to obtain a uniform temperature distribution, making it extremely difficult to create a precise black body furnace. It was difficult.
この発明の目的は、以上の点に鑑み、球形の炉体を複数
個の棒状支持部材を介して箱体に収納し、箱体内部に位
置した加熱体で炉体を加熱することにより、より精密な
黒体炉とされた球形炉を提供することである。In view of the above points, an object of the present invention is to house a spherical furnace body in a box body through a plurality of rod-shaped supporting members, and to heat the furnace body with a heating element located inside the box body. The object of the present invention is to provide a spherical furnace that is a precise blackbody furnace.
第２図は、この発明の一実施例を示す断面図である。FIG. 2 is a sectional view showing an embodiment of the present invention.
図において、１は内部が中空の球形の炉体、７は、この
炉体１を収納する箱体、８は箱体７の内部に設けられ、
炉体１を浮かして固定するための複数個の棒状支持部材

被校正用放射温度計を校正するための開口部である。In the figure, 1 is a hollow spherical furnace body, 7 is a box housing the furnace 1, 8 is provided inside the box 7,
A plurality of rod-shaped support members for floating and fixing the furnace body 1; 2 are heating elements located on the top, bottom, left and right sides of the inside of the box body 1 to heat the furnace body 1; 5 is a temperature sensor such as a thermocouple for measuring the furnace temperature; 1a is an opening 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７の内部に設
けられた加熱体２を通電発熱し、この加熱体２の熱によ
り球形の炉体１を関接加熱する。In the spherical furnace having such a configuration, first, the heating body 2 provided inside the box body 7 generates heat by energizing it, and the spherical furnace body 1 is indirectly heated by the heat of the heating body 2.
この時箱体７の内部は密閉状態とされており、炉体１と
箱体７との空間は空洞放射により均熱となっているとと
もに、炉体１は棒状支持部材８により浮かし，て固定さ
れ、炉体１はほとんど均一の温度とされる。At this time, the inside of the box body 7 is sealed, and the space between the furnace body 1 and the box body 7 is uniformly heated by cavity radiation, and the furnace body 1 is suspended and fixed by the rod-shaped support member 8. The temperature of the furnace body 1 is almost uniform.
従って炉体１の内部は極めて理想的な黒体条件となり、
開口部１ａより被鼓正用放射温変計で炉体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。Therefore, the inside of the furnace body 1 has extremely ideal blackbody conditions,
The radiation thermometer can be calibrated by aiming the inside of the furnace body 1 with the radiation temperature variable meter to be calibrated through the opening 1a and measuring the furnace temperature with the thermometer 5.
以上、詳述し，たように、この発明は、球形の炉体を複
数個の棒状支持部材を介して箱体に収納し、箱体内部に
位置した加熱体により炉体を加熱するようにした球形炉
である。As described above in detail, the present invention has a method in which a spherical furnace body is housed in a box body through a plurality of rod-shaped support members, and the furnace body is heated by a heating element located inside the box body. It is a spherical furnace.
従って、球形の炉体に加熱体をまく必要がないので、そ
れだけ製作が容易であり、又、絶縁をとる必要もないの
で炉体を軽くすることができ、固定台も不要である。Therefore, since there is no need to cover the spherical furnace body with heating elements, manufacturing is easier, and since there is no need for insulation, the furnace body can be made lighter and no fixing stand is required.
又、球形の炉体が箱体内部に浮かし，て固定され、加熱
体により炉体を加熱するようになっているので、箱体内
部は空洞放射により均熱とされ、炉体も極めて均一の温
度となり、炉体内部は理想的な黒体条件となる。In addition, the spherical furnace body is suspended and fixed inside the box body, and the furnace body is heated by a heating element, so the inside of the box body is uniformly heated by cavity radiation, and the furnace body is also extremely uniform. temperature, and the inside of the furnace body becomes ideal blackbody conditions.
精密な標準黒体炉として実用的効果が太きい。It has great practical effects as a precision standard blackbody furnace.
