摘要： Metallic pieces of predetermined shape, e.g., anodes, are continuously manufactured from molten metal, e.g., impure molten copper, by continuously casting the molten metal in an inclined mold cavity (13) formed by two endless moving belts (14( and (15) and by two moving side dams (20) and (21) so as to produce a hot metallic strip (4), and by cutting the hot strip, when it has left the mold cavity, with at least one plasma torch (10) along a profile (27) such that anodes (11) with a low waste coefficient are obtained. In this way, flat copper anodes with a thickness of between 40 and 50 mm can be produced.

摘要： In an apparatus for conveying dripping electrodes, a drop collector having a plurality of parallel gutters is coupled to the conveying apparatus by a frame. The gutters are coupled together in one or more series of parallel gutters and are displaced by a motor driven endless chain system between a work position underneath the suspended dripping electrodes and a rest position which permits the electrodes to be inserted into or extracted from electrolysis cells by the conveying apparatus. The gutters include outlet orifices which communicate electrolyte from the dripping electrodes to a reservoir formed in the frame which couples the drop collector to the conveying apparatus.
