ABSTRACT:
A roller electrode, to be used for the support of sheet-metal strips in an electrorefining bath, has a hollow-cylindrical steel body spacedly surrounded by steel tubing for the circulation of a cooling fluid. A thin-walled shell of steel or nickel alloy, spacedly enveloping the tubing, defines with the roller body an annular space filled with a mass of lower-melting metal such as copper in which the tubing is embedded. The shell may extend partly around two stub shafts extending integral with the roller body at opposite ends therefrom. In making the electrode, the shell is heated above the melting point of the lower-melting metal which is then introduced in a molten state into the space containing the tubing where it is allowed to harden.
