Abstract

De huidige uitvinding heeft betrekking op een werkwijze voor het elektrolytisch verzinken van draadstangen, omvattende het aanbrengen van een veelheid draadstangen in een geperforeerde trommel via een overlangse sleuf en het sequentieel onderdompelen van de trommel in volgende vier baden: een ontvetbad, een beitsbad, een zinkbad, voorzien van een zure, waterige oplossing die zinkionen en chloride-ionen omvat, en een passiveerbad, waarbij de trommel tijdens het onderdompelen in het zinkbad gezwenkt wordt tussen een hoek van 180° en -180°. In het bijzonder zullen de draadstangen verenkeld en verdeeld worden tijdens het zwenken middels een interne hoek aanwezig in de trommel. De uitvinding heeft eveneens betrekking op een inrichting voor het elektrolytisch verzinken van draadstangen omvattende: een van een sleuf voorziene, prismavormige trommel met geperforeerde zijvlakken, en een hangbaan voorzien van ophangelementen, zwenkbaar gekoppeld aan het grond- en bovenvlak van de trommel, waarbij de hangbaan is uitgevoerd met ten minste een daling en tenminste een stijging voor het respectievelijk neerwaarts in een bad en opwaarts uit het bad voeren van de trommel. In het bijzonder bezit één van de zijvlakken van de trommel over de lengte een geul.The present invention relates to a method for electrolytically galvanizing threaded rods, comprising inserting a plurality of threaded rods into a perforated drum through a longitudinal slot and sequentially immersing the drum in the following four baths: a degreasing bath, a pickling bath, a zinc bath , provided with an acidic, aqueous solution comprising zinc ions and chloride ions, and a passivation bath, in which the drum is pivoted between an angle of 180° and -180° during immersion in the zinc bath. In particular, the threaded rods will be separated and divided during pivoting by means of an internal angle present in the drum. The invention also relates to an apparatus for electrolytically galvanizing threaded rods, comprising: a slotted, prism-shaped drum with perforated side surfaces, and an overhead track provided with suspension elements, pivotally coupled to the base and top surface of the drum, wherein the overhead track is provided with at least one descent and at least one rise for carrying the drum downwards into a bath and upwards out of the bath, respectively. In particular, one of the side surfaces of the drum has a groove along its length.
