<p>An alloyed copper wire rod is formed by continuous rod-casting, wherein a core rod is driven through a crucible containing molten metal. High purity copper melt is continuously charged into the crucible; to which an alloying material is simultaneously added in a quantity which corresponds to the given casting speed of the core rod. The required alloy thus obtained is crystallized on the surface of the core-rod as it passes through the crucible and the rod produced is treated in the usual manner i.e., cooling, rolling and coiling.</p> |
