Process parameters for continuous melting-casting and rolling of copper rod

Claim 2

The method of claim 1 in which the temperature of the as-cast bar at its point of removal from the rotary mold is maintained within the range between about 1,700* F. and about 1,750* F.

Claim 3

The method of claim 1 in which the oxygen content is maintained within the range between 0.035 percent and 0.040 percent by weight.

Claim 4

In the method of producing copper rod in which the copper is continuously melted, continuously cast in a rotary mold, conditioned and hot-worked into rod form without any intermediate reheating, the improvement of steps comprising, controlling the temperature of the molten copper at its point of entry into the rotary mold continuous casting machine to a temperature within the range between about 2,025* F. and about 2,050* F. while also maintaining the oxygen content of the molten metal to a value within the range between about 0.035 percent and about 0.040 percent by weight, controlling the speed of rotation mold to complete solidification of the cast bar before the bar reaches the pouring level of the molten metal while maintaining the temperature of the solidified bar within the range between about 1,700* F. and 1,750* F. at the point of release of the solidified bar from the rotary mold, conditioning the bar and commencing hot working the bar without any intermediate reheating when the bar is at a temperature within the range between 1,600* F. and about 1,625* F.
