ABSTRACT:
A method and apparatus for the continuous production of bright copper rod from stock discharged from a continuous casting machine in which an oxide layer formed on the stock during its passage from the continuous casting machine in the atmosphere is subjected to an initial breakage and separation operation by discharging a chemically active liquid at a relatively low pressure against the oxide layer followed by descaling the stock after the initiation of the breakage of the layer by projecting jets of liquid at a relatively high pressure against the stock. The stock which is now free from oxide layer is rolled in a rolling mill in the presence of cooling and lubricating liquid which isolates the stock from the outside atmosphere and allows the formation of rod in the stands of the rolling mill. The rod obtained from the rolling mill is cooled by passage through a duct in counterflow with a cooling liquid such that the rod leaves the duct at a temperature below 80.degree. C.
