Abstract
This invention relates to a method for removing an oxide scale from the surface of a hot rolled copper rod in an in-line process. The method comprises the steps of passing the rod through a chamber containing a reducing atmosphere, the chamber being immediately adjacent to the exit end of the rod rolling mill. The rod passes through the hydrogen containing chamber while it is still hot from the rolling operation, and the reducing atmosphere reduces the oxide scale to metallic copper. After passing through the chamber, the rod is cooled in an aqueous bath and then coiled.
