Electroslag remelting plant - using two electrode holders, each mounted on a swivel arm for rapid electrode replacement

Plant for the casting of ingots by electroslag remelting, where consumable electrodes are successively fed into the mould. On each side of the mould is a pillar on which a trolley can be driven vertically, and each of the two trolleys has a horizontal pivot shaft for a lever arm. The end of the arm has a higned mounting for an electrode carrier and the arm can be driven in an arc in a vertical plane to move an electrode onto the axis of the mould. When the lever arm locates an electrode on the mould axis, the arm is pref. in contact with a plate feeding electric current to the electrode, and a supporting bracket holds the arm when an electrode is replaced. In one pref. plant a sensor indicates the presence of the lever arm in its working position, i.e. when an electrode is on the mould axis. As soon as one electrode has been consumed, it can be swung by its lever arm away from the mould axis so a new preheated electrode can be moved into the mould via the second lever arm. L'INVENTION CONCERNE LA METALLURGIE.L'INSTALLATION FAISANT L'OBJET DE L'INVENTION EST CARACTERISEE NOTAMMENT EN CE QUE CHAQUE PORTE-ELECTRODE 3 EST RELIE AU CHARIOT 15 CORRESPONDANT PAR UN BRAS 19 DONT L'UNE DES EXTREMITES EST RELIEE A CE CHARIOT DE FACON QUE SON AUTRE EXTREMITE, SUR LAQUELLE EST FIXE LE PORTE-ELECTRODE, SE DEPLACE SUIVANT UN ARC DE CERCLE SITUE DANS UN PLAN VERTICAL.L'INVENTION S'APPLIQUE NOTAMMENT A LA FABRICATION DE LINGOTS DE DIMENSIONS RELATIVEMENT IMPORTANTES.
