Abstract
Consumable electrodes are transferred to and from an operative position in an underlying melting bath by means of a pair of lifts that are vertically movable on masts located on opposite sides of the mold axis. One of the lifts has a fixed portion extending transversely through the axis and toward the other lift, and has a recess aligned with the mold axis and with the path of oscillation of an electrode-transferring arm carried by the other lift. When an electrode is transferred into the recess, a collar on the electrode is clamped to the upper surface of the fixed portion, whereupon the first lift is moved downwardly to position the inserted electrode into the mold. Consumed electrodes are removed by raising the first lift, and engaging a lifting collar on the upper end of the residual portion of the electrode by an arm that is carried for vertical movement and oscillation by the first lift. After such additional arm is oscillated away from the recess with the consumed electrode, the arm on the second lift can be actuated to transfer a new electrode into the recess.
