〈産業上の利用分野〉
この発明は、高温加熱炉に用いられる発熱体を支持する
ための発熱体の支持方法に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for supporting a heating element for supporting a heating element used in a high-temperature heating furnace.
〈従来の技術〉
高温加熱炉においては、基台上に二珪化モリブデン発熱
体の両端を支持して保持すれば、二珪化モリブデン発熱
体が高温で剛性を失って撓んでしまう。<Prior Art> In a high-temperature heating furnace, if both ends of a molybdenum disilicide heating element are supported and held on a base, the molybdenum disilicide heating element loses its rigidity and bends at high temperatures.
そのため、従来においては、二珪化モリブデン発熱体全
体を支持台上に接触させて載置していた。Therefore, in the past, the entire molybdenum disilicide heating element was placed on a support stand in contact with it.
ところが、このような発熱体の支持方法では、二珪化モ

発熱体および支持台の夫々の寿命が短かくなるという問
題がある。However, in this method of supporting a heating element, when the molybdenum disilicide heating element expands and contracts, mechanical resistance is generated due to friction between the molybdenum disilicide heating element and the support base, causing the element to bend or bend. There is a problem that the molybdenum disilicide heating element is damaged. In addition, in the above method for supporting a molybdenum disilicide heating element, since the entire lower surface of the molybdenum disilicide heating element is in direct contact with the upper surface of the support base, the heat generated by the molybdenum disilicide heating element is transferred to the molybdenum disilicide heating element and the supporting base. There is a problem in that a chemical reaction or welding occurs between the molybdenum disilicide heating element and the support, resulting in a shortened lifespan of the molybdenum disilicide heating element and the support.
〈発明・の目的〉
そこで、この発明の目的は、熱膨張時における発熱体の
伸縮時、発熱体と支持台との間の摩擦を極力減少させて
機械的抵抗を少なくし、発熱体の損傷を防止し、また発

熱体および支持台の長寿命化を達成することにある。<Objective of the Invention> Therefore, an object of the present invention is to minimize the friction between the heating element and the support base when the heating element expands and contracts during thermal expansion, thereby reducing mechanical resistance and preventing damage to the heating element. The object of the present invention is to prevent chemical reactions and welding between the heating element and the support, thereby extending the life of the heating element and the support.

ーズ２の上に略水平に設置することを特徴とする。<Structure of the Invention> In order to achieve the above object, the method for supporting a heating element of the present invention is as illustrated in FIG. It is characterized by being installed approximately horizontally on top of the mullite beads 2.
〈発明の作用〉
発熱体４の下面全体は、支持台！上に略均一に敷きつめ
られたムライトビーズ２に一様に接触して支持される。<Operation of the invention> The entire lower surface of the heating element 4 is a support base! It is supported by uniformly contacting the mullite beads 2 spread almost uniformly on top.
そのため、発熱体４が熱膨張で伸縮しても発熱体４は、
転がるムライトビーズ２上を移動するのみであり、発熱

熱体４と支持台１との間の化学反応や溶着は起こらない
。Therefore, even if the heating element 4 expands and contracts due to thermal expansion, the heating element 4
The heating element 4 only moves on the rolling mullite beads 2, and no mechanical resistance acts on the heating element 4. therefore,
Damage to the heating element 4 is prevented. Furthermore, since the mullite beads 2 are interposed between the heating element 4 and the support I, no chemical reaction or welding occurs between the heating element 4 and the support I.
〈実施例〉 以下、この発明を図示の実施例により詳細に説明する。<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

The molybdenum disilicide heating element 4 has both ends 4a and 4b connected to lead wires (not shown), and its heating portion 4C is placed on the mullite bead 2 substantially horizontally.
上記支持台１上にムライトビーズ２を介してニ珪化モリ
ブデン発熱体４を載置したものが高温加熱炉の所定場所
に複数個設置されている。A plurality of molybdenum disilicide heating elements 4 mounted on the support base 1 via mullite beads 2 are installed at predetermined locations in a high-temperature heating furnace.
上記支持台Ｉの凹部１ａに略均一に敷きつめられたムラ

部全面は略一様に支持されている。The entire lower part of the molybdenum disilicide heating element 4 is supported substantially uniformly by the mullite beads 2 spread substantially uniformly in the recess 1a of the support base I.
したがって、支持台ｌと二珪化モリブデン発熱体４の間
で二珪化モリブデン発熱体４は自重で撓むことはない。Therefore, the molybdenum disilicide heating element 4 does not bend due to its own weight between the support base 1 and the molybdenum disilicide heating element 4.

デン発゛熱体４との間での化学反応も溶着も生じない。Since the mullite beads 2 are interposed, even if the molybdenum disilicide heating element 4 expands and contracts due to thermal expansion, the molybdenum disilicide heating element 4 only moves on the mullite beads 2 as a roller, resulting in a large frictional force, i.e. , is not subjected to mechanical resistance. Therefore, molybdenum disilicide heating element 4
is not subject to damage such as bending, buckling, or abrasion. Moreover, since the mullite beads 2 between the support base 1 and the molybdenum disilicide heating element 4 are chemically and physically stable, when the molybdenum disilicide heating element 4 generates heat, the mullite beads 2 between the support base 1 and the molybdenum disilicide Neither chemical reaction nor welding occurs with the heating element 4.
したがって、支持台Ｉおよび二珪化モリブデン発熱体４
は共に長寿命となる。Therefore, the support base I and the molybdenum disilicide heating element 4
Both have a long life.
