Description
Die Erfindung betrifft ein Verfahren zum Abreinigen gegossener Kupferanoden von anhaftenden Resten einer Kalk- und Schwerspatverkrustung, wobei die aus der Gießhitze noch ca. 700 bis 900 °C heißen Platten in ein längliches Wasserkühlbecken Zeingesetzt und darin bei taktweisem Transport zu einem Aushebebereich gefördert und, an diesem angekommen, mit einer Aushebeeinrichtung an eine anschließende Bündelungsvorrichtung zur weiteren Verwendung übergeben werden.The invention relates to a method for cleaning cast copper anodes from adhering residues of lime and heavy spar encrustation, the from the Pouring heat of plates at a temperature of approx. 700 to 900 ° C into an elongated water cooling basin Set in and with it in cycles to a lifting area promoted and, once arrived, with a lifting device hand over a subsequent bundling device for further use become.
Kupferanoden werden im industriellen Produktionsablauf üblicherweise auf einem Gießkarussell erzeugt, wobei flüssiges Kupfer in entsprechend geformte Kokillen gegossen wird. Die Kokillen werden hierbei mittels einer z. B. Bariumsulfatlösung, der sogenannten "Kalkmilchschlichte", zusammengesetzt aus Kalkmilch und Schwerspat, behandelt und gegen Auswaschen sowie zu intensiven Wärmeübergang geschützt, wobei die Lösung auch als Trennmittel eingesetzt wird.Copper anodes are usually made on one in the industrial production process Casting carousel created, liquid copper in appropriately shaped molds is poured. The molds are here by means of a z. B. barium sulfate solution, the so - called "lime milk sizing", composed of lime milk and Heavy spar, treated and against washing out and excessive heat transfer protected, the solution also being used as a release agent.
Nach dem Erstarren werden die noch ca. 700 bis 900 °C heißen Anoden vom Karussell mittels einer auf einem unmittelbar anschließenden Kühlbecken angeordneten Abhebevorrichtung in das Wasserbad des Beckens eingetaucht. Darin werden die Anoden taktweise zu einem Aushebebereich transportiert und mittels einer Aushebevorrichtung an eine anschließende Bündelungsvorrichtung weitergegeben (DE-A-2 309 358). After solidification, the anodes, which are still approx. 700 to 900 ° C, are removed from the carousel by means of one arranged on an immediately adjacent cooling basin Lifting device immersed in the pool's water bath. In it the anodes are cyclically transported to a lifting area and by means of a Lifting device passed on to a subsequent bundling device (DE-A-2 309 358).
Im Interesse einer zügigen Weiterverarbeitung müssen dabei die Seitenflächen bzw. eine derselben, die aus dem Gießprozeß mit einer Kalkschwerspatkruste, der sogenannten "Schlichte" belegt sind, gründlich derart abgereinigt werden, daß nur noch unwesentliche Rest der Verkrustung zurückbleiben, je weniger, je besser.In the interest of speedy further processing, the side surfaces or one of the same, which results from the casting process with a limestone scab crust, the So-called "size" are documented, thoroughly cleaned so that only still insignificant rest of the incrustation remain, the less, the better.
Falls die Verkrustung oder Teile davon im nachgeschalteten Produktionsschritt, der Elektrolyse, nicht oder nur unvollkommen beseitigt sind, schlägt sich bei der Reinstkupfererzeugung die "Schlichte" im Elektrolyseschlamm nieder. Dieser mußte bisher dann mit äußerst großem zeitlichen und entsprechend finanziellem Aufwand aus dem Elektrolyseschlamm getrennt werden.If the incrustation or parts of it in the downstream production step, electrolysis, not or only incompletely removed, is reflected in the Pure copper production the "size" in the electrolysis sludge. This So far had to be extremely large in terms of time and financial Effort can be separated from the electrolysis sludge.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine zu dessen Durchführung geeignete Vorrichtung anzugeben, mit deren Hilfe eine gründliche Abreinigung der Anoden vor dem Produktionsschritt "Elektrolyse" mit wirtschaftlichen Mitteln im Einklang mit den taktweisen Produktionsschritten der Produktionskette, insbesondere beim Gießen und Kühlen der Anoden, erreicht werden kann.Proceeding from this, the object of the invention is a method and specify a device suitable for carrying it out, with the help of which thorough cleaning of the anodes before the "electrolysis" production step with economic means in accordance with the cyclical production steps of the production chain, especially when casting and cooling the anodes can be.
