ABSTRACT:
An apparatus and method for continuously cleaning and coating wire is disclosed in which rod having scale and other inpurities on its outer surface is first mechanically descaled by passage through a plurality of spatially positioned rollers, then cleaned by frictional scraping by at least two rotating and orbiting abrasive drums which scrape the entire outer surface of the rod. The cleaned rod is then covered by a coating solution and electrically heated to a temperature sufficient to bake a coating on the exterior surface of the rod. The rod is then passed to a drawing apparatus.
