    摘要： PROBLEM TO BE SOLVED: To provide an electrode connection device capable of easily and surely performing the alignment of a new electrode. SOLUTION: This electrode connection device comprises a holding and rotating member 2 holdingly rotating the new electrode a, a first suspending member 3 connected to the top part of the holdingly rotating member 2, a second suspending member 4 for swingably suspending the first suspending member 3 from the upper part thereof, and a third suspending member 5 for swingably suspending the second suspending member 4 from the upper part thereof. Thus, even if the angles and positions of the new electrode a and an existing electrode b are slightly displaced, the angles and positions of the new electrode a are automatically corrected and aligned according to the existing electrode b when the new electrode a is screwed into the existing electrode b. As a result, a connecting operation can be easily performed. COPYRIGHT: (C)2003,JPO

    摘要： PCT No. PCT/FR91/00215 Sec. 371 Date Nov. 19, 1991 Sec. 102(e) Date Nov. 19, 1991 PCT Filed Mar. 15, 1991 PCT Pub. No. WO91/14912 PCT Pub. Date Oct. 3, 1991.A direct current electric furnace for melting metal raw material, especially scrap iron, comprises two consumable electrodes separated from one another and both offset laterally on the side of the median plane P1 of the vessel turned towards the current source. At least four fixed electrodes are distributed on either side of the median plane and arranged substantially at the vertices of a regular polygon symmetrical with respect to the median plane and placed between the vertical projections of the consumable electrodes, the conductors of the electrodes placed towards the source being orientated directly towards the latter, parallel to the conductors of the consumable electrodes and the conductors of the electrodes placed on the side opposite to the source each comprising a first branch passing around the vertical projection of the corresponding consumable electrode and a second branch orientated towards the source parallel to the conductors connected to the consumable electrodes.

    摘要： 【課題】スティンガーロッドのロッドプラグとプラグソケットとの間の所要の電気的接続性を確保しつつ、スタブソケット内へのロッドプラグの意図しない嵌合を有効に防止して、スタブソケットからロッドプラグを容易に分離することのできる消耗電極式アーク溶解炉を提供する。 【解決手段】スタブソケット1のテーパ内面2を、ロッドプラグ3の円錐台先端部5のテーパ外面5aに接触する下段テーパ面2aと、前記下段テーパ面2aより上方側に位置し、前記下段テーパ面2aに比して、該スタブソケット1の中心軸線CLに直交する平面に対するテーパ角度が小さい上段テーパ面2bとを含む二段階以上のテーパ面で構成し、ロッドプラグ3の円柱基部4を、スタブソケット1のテーパ内面2と非接触とする。 【選択図】図1
