The invention is based on the object

ao knew devices for the production of electrodes from blister copper and / or copper scrap for electrolytic copper refining and thereby to achieve a reduction in manufacturing costs.

This object is achieved by a device that uses a continuously operating continuous casting machine of the type described above with driven, water-cooled, endless, parallel metal belts has, behind the rollers for guiding the cast with perfectly flat surfaces Copper strips are arranged, for cutting and further processing of the copper strips to Plate-cut anodes, flying scissors, a press for making holes and recesses in the cut copper plates for a suspension device and a feed device to serve.

Another feature of the invention is for cooling the recessed ano-

The invention relates to an apparatus for producing continuously cast electrodes from blister copper and / or copper scrap for electrolytic copper refining.

In the deposition of satisfactorily pure copper in an electrolytic refining process the rate of deposition is limited to such an extent that until complete dissolution

of the built-in electrodes a time of several 40 to one chamber is provided, whereby weeks may be required for transport. As a result, a chain conveyor is used for the production of refined copper anodes equipped with a copper rod and pairs of hooks,
a large number of extensive baths required The device according to the invention is one of those that require a weighty capital expenditure for great economic importance for the electrolytic plants and buildings. In order to observe this copper refining, since it is kept as low as possible by the application, the above-described, known method is used in practice to combine the unrefined electrodes continuously with the greatest possible surface area with the downstream connection of the other units and bring them as close as possible into the electrolyte directions for cutting the copper strips, for table baths, without making holes or recesses for or with the laminated cathode plates for hanging up the anodes manufactured in this way etc. come into contact, which makes it a bit short-lived to work much more efficiently than at the end. The term used "above the usual casting of the anodes in an open mold area" means the surface area of a men. The electrodes manufactured with the device according to the invention on the electrode side, ie length times width of the electrodes, have flatter and smoother electrodes. Surfaces, and their dimensions are more precise than these-
