Abstract
A process for the continuous manufacture of copper wire rod presenting both the good ductility of oxygen-free copper and the annealing capacity of the tough pitch copper, in which liquid copper is prepared containing from about 0.006 to 0.0095% by weight of oxygen, the said liquid copper is cast via an open pouring spout in a continuous casting machine having an inclined straight molding cavity for producing a continuous copper bar containing 0.01 to 0.02% by weight of oxygen and which consists of a shell of solid copper and a core of liquid copper, the said bar on leaving the casting machine is cooled by repeated and direct contact with a cooling agent for complete solidification and the solidified bar is guided towards a horizontal rolling mill known 'per se' along a curved path the maximum curvature of which is less than 0.25 m.sup.-1, and the said bar is rolled into wire rod.
