インサートに供給される。The contact head in a conventional electrode holding device for an arc furnace consists of a body and two inserts fixed to the body with bolts, etc. In the center of these inserts is a water-cooled tube through which cooling water flows. A tube is provided. The body is then connected to a tubular busbar that supplies current. This current is then supplied from the body to these inserts via the contact surface of each insert with the body.

重量が重かった。In such conventional devices, the contact surface between the hot spring and the insert is contaminated, which may cause the insert to be welded to the body. When the insert is welded to the head in this way, there is a problem in that the entire contact head must be replaced. For this reason, the work was troublesome and inefficient. Additionally, this conventional device had a complicated structure and was heavy.
本発明は以上の事情に基づいてなされたもので、その目

This is achieved by electrically and mechanically connecting the top of this insert to the plate flange. These inserts are equipped with water cooling pipes through which cooling water flows.
A vertical groove is formed on the contact surface of the insert corresponding to the front side of the water cooling pipe.
また、本発明の実施例ではインサートはボディに対して

されている。An embodiment of the present invention will be described below with reference to the drawings. 1st
Reference numeral 1 in the figures and FIG. 2 is an insert, and this insert 1 is made of copper material. A water cooling pipe 2 is provided behind the plurality of vertical grooves 3 formed in the contact surface 4 of the insert 1. Further, holes 5115 for attaching the plate flange 7 with bolts and holes 6 for attaching the cooling device (FIG. 3) are formed in the upper part of the insert 1. And, Fig. 3 J3 and 4
As shown in the figure, the plate flange 7 is connected by a plate 9 and bolts 10 to a copper tubular bus bar 8, through which current is supplied. The copper insert 1 is electrically and mechanically connected to the plate flange 7 by bolts 11. The above-mentioned body 13 is made of stainless steel WJ, and the above-mentioned insert 1 comes into contact with a seat 12 formed in this body 13, and is electrically insulated from this body 13 by an asbeth I-plate 14. . Also,
Cooling water is supplied via piping 15. The insert 1 is fixed to the electrode 16 by a pressing jaw 17.
アーク炉の作動中において、上記のインサート１から黒
鉛製の電極１６への電流の供給は、このインサート１の
接触面４を介しておこなわれる。During operation of the arc furnace, the supply of current from the insert 1 to the graphite electrode 16 takes place via the contact surface 4 of this insert 1.
また、上記の水冷管２は前述の如く黒鉛製の電極１６に
接触することない位置に対応して配置されているので、
このインサート１と電極１６と間の接触面に周期的に発
生するアークによってこの水冷管２が破裂するのが防止
される。また、これらのインサート１の一方が損傷ある
いは摩耗した場合にはこの損傷したインサートだけを交
換することができ、従来のもののように接触ヘッド全体
を交換する必要はない。In addition, since the water-cooled tube 2 is placed in a position where it does not come into contact with the graphite electrode 16, as described above,
The arc periodically generated at the contact surface between the insert 1 and the electrode 16 prevents the water-cooled tube 2 from bursting. Furthermore, if one of these inserts 1 becomes damaged or worn, only this damaged insert can be replaced, without having to replace the entire contact head as in the conventional case.
また、これらのインサート１は従来のものより軽量に形
成でき、その結果非鉄金属材料を節約することができる
。また上記のボディ１３は交換されずに残り、このボデ
ィ１３は単にインサート１等の支持をなすだけのもので
、電流の伝導の作用はなさず、このボディ１３はステン
レス鋼で形成できる。These inserts 1 can also be made lighter than conventional ones, so that non-ferrous metal materials can be saved. Further, the body 13 described above remains without being replaced, and this body 13 merely supports the insert 1 etc., and does not perform the function of conducting current, and this body 13 can be made of stainless steel.
