Description
【考案の詳細な説明】
本考案は、抵抗発熱体及び電極を結合する手段を設けた
抵抗発熱体電気炉に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resistance heating element electric furnace provided with means for coupling a resistance heating element and an electrode.
従来、この種の電気炉は極めて高温の発熱体と低温の電
極を電気的、機械的に結合しなければならず、上記発熱
体及び電極との間の温度差が極めて大きいため、両者を
結合することに難点があった。Conventionally, in this type of electric furnace, an extremely high-temperature heating element and a low-temperature electrode had to be electrically and mechanically connected, and since the temperature difference between the heating element and the electrode was extremely large, it was difficult to connect the two. There were some difficulties in doing so.
例えば、全発熱体に直接電極をねじ込む方法や、電極の
溝に発熱体の一部を差し込み、楔を打ち込んで接続する
方法等があるが、これらは発熱体の温度上昇に伴った熱
変形による接続抵抗が増加し、接続部分が消耗しやすく
、又発熱体の交換が煩雑になる等の欠点があった。For example, there are methods such as screwing the electrode directly onto the entire heating element, or inserting a part of the heating element into the groove of the electrode and driving a wedge to connect. There were disadvantages such as increased connection resistance, easy wear of the connecting parts, and complicated replacement of the heating element.
本考案は、上記従来の欠点を解消するために、発熱体と
電極との結合をカーボン等の耐熱導電材料によって作製
されたボルトによって行うことを特徴とし、その目的は
熱変形による接続抵抗の増加を生じることがなく、発熱
体及び電極の接触部分の消耗を防止し、発熱体の交換を
容易にした抵抗発熱体電気炉を提供するものである。In order to eliminate the above-mentioned conventional drawbacks, the present invention is characterized in that the heating element and the electrode are connected using bolts made of a heat-resistant conductive material such as carbon.The purpose of this invention is to increase the connection resistance due to thermal deformation. To provide a resistance heating element electric furnace which prevents wear and tear of the contact portion between the heating element and the electrode, and facilitates replacement of the heating element.
以下、図面により実施例を詳細に説明する。Hereinafter, embodiments will be described in detail with reference to the drawings.
図は、本考案の１実施例を示したもので、１はカーボン
抵抗発熱体、２はカーボンボルト、３は水冷銅製電極で
ある。The figure shows one embodiment of the present invention, in which 1 is a carbon resistance heating element, 2 is a carbon bolt, and 3 is a water-cooled copper electrode.
この水冷銅製電極３の発熱体１との接触部分は通常の加
工研磨が施こされ、表面を平滑にしている。The contact portion of the water-cooled copper electrode 3 with the heating element 1 is subjected to ordinary processing and polishing to make the surface smooth.
発熱体１は電極３との接続のためにリード部４が設けら
れ、このリード部４を電極３の平滑部に乗せ、カーボン
ボルト２で締め付は固定する。The heating element 1 is provided with a lead part 4 for connection to the electrode 3, and the lead part 4 is placed on the smooth part of the electrode 3 and fixed by tightening with a carbon bolt 2.
以上のように、本実施例はカーボンボルト２で発熱体１
と電極３を固定しているので、発熱体リード部４の熱変
形がカーボンボルト２で吸収され、接続部分の熱変形に
よる抵抗増加をなくすことができる。As described above, in this embodiment, the heating element 1 is connected to the carbon bolt 2.
Since the electrode 3 is fixed, the thermal deformation of the heating element lead portion 4 is absorbed by the carbon bolt 2, and an increase in resistance due to thermal deformation of the connecting portion can be eliminated.
又このカーボンボルト２を介して通電するため、発熱体
と電極との間に接続抵抗の増加のおそれがなく、又カー
ボンボルト２によって接触部を密着させることができる
ため、接触部分の熱や放電による消耗がなく、更に発熱
体１の交換はカーボンボルト２の抜き締めのみによって
行なうため、ねじ込み電極のように電極自体を動かす必
要がなく、発熱体の交換は極めて容易である。In addition, since electricity is passed through the carbon bolts 2, there is no risk of an increase in connection resistance between the heating element and the electrode, and since the carbon bolts 2 allow the contact parts to be brought into close contact, there is no heat or discharge at the contact parts. Furthermore, since the heating element 1 can be replaced by simply pulling out and tightening the carbon bolt 2, there is no need to move the electrode itself unlike a screw-in electrode, and the heating element can be replaced very easily.
以上説明したように、本考案によれば、発熱体と電極の
結合をカーボン等の耐熱導電性材料によって行なうため
、温度変化による接続抵抗への影響がなく、完全に電気
的、機械的に発熱体と電極とを接続することができる利
点がある。As explained above, according to the present invention, since the heating element and the electrode are bonded using a heat-resistant conductive material such as carbon, the connection resistance is not affected by temperature changes, and heat is generated completely electrically and mechanically. There is an advantage that the body and the electrode can be connected.
