Title:
【発明の名称】酸化した熱間圧延銅棒を清浄にするための方法
Document Type and Number:
Japanese Patent JP2003533591
Kind Code:
A
Abstract:
The invention relates to a process for cleaning oxidized, rolled copper rods which, after casting in a continuously operating continuous-casting device, emerge from a rolling mill arranged downstream of the continuous-casting device and which, on emerging from the rolling mill, have oxidic layers on their surface. The process is characterized, inter alia, in that the oxidized, finish-rolled rod is passed through one or more reduction zones at a temperature of approx. 650° C.; in that a dilute, aqueous hydrocarbon-containing solution is used as reducing liquid in the reduction zone(s), and in that the rate at which the chemical reactions for reducing the two types of oxide which are present is made more intensive by making the bath turbulent by means of one or more ultrasound sources.
