摘要： A current-conducting arm for conducting a current from at least one cable supports to an electrode in an electric arc furnace comprising an arm housing having a U-shaped base channel member and a U-shaped top channel member. Both channel members have a first and second wall, with the top channel member being inverted such that the first wall of the top channel member can be joined with the first wall of the base channel member, and the second wall of the top channel member can be joined with the second wall of the base channel member. The arm housing therefore has four annular corners to improve the conduction of current through the arm housing to the electrode. The invention further includes a spring assembly used to provide to aid an electrode holder in clamping the electrode. Moreover, a laser pointer is included for guiding the positioning of the arm housing in the electric arc furnace.
摘要翻译：一种用于将电流从至少一个电缆支撑件传导到电弧炉中的电极的导流臂，其包括具有U形基部通道构件和U形顶部通道构件的臂壳体。两个通道构件具有第一和第二壁，顶部通道构件被倒置，使得顶部通道构件的第一壁可以与基部通道构件的第一壁接合，顶部通道构件的第二壁可以与基底通道构件的第二壁连接。因此，臂壳体具有四个环形角，以改善通过臂壳体到电极的电流传导。本发明还包括弹簧组件，其用于提供电极夹持器夹持电极。此外，包括用于引导臂壳体在电弧炉中的定位的激光指示器。

摘要： An electrode seal for an electric arc furnace comprises an annular support ring having an internal diameter substantially greater than the diameter of the electrode, and which is secured to the furnace roof by a plurality of mounting feet. The annular support ring has an upper annular sealing surface on which is supported an annular sealing ring having an internal diameter which is approximately the same as the diameter of the electrode to form a substantial seal therewith. The sealing ring has a lower annular sealing surface which engages the upper sealing surface of the support ring, while allowing limited sliding movement of the sealing ring along its lower annular sealing surface.
