<p>Suspension bar for an anode or cathode sheet in electrolytic refining of metals, the core (9) of the suspension bar consisting of a material which exhibits a high resistance to bending and a high mechanical resistance, and being surrounded by a sheath (8) of a material with good electrical conducting properties, such as copper. The core material is a material with good electrical conduction properties, such as copper, near at least one of the ends (10) of the suspension bar, preferably near both ends, over a length of a least 3 cm and at most 5 cm, the sheath being continuous to the end of said core part. Method for manufacturing such a suspension bar in which a sheath of copper is drawn over a core of steel, starting from copper tube. Copper and steel cores are alternately introduced into the copper tube, subsequently the sheath is drawn, with further cores being added, to a total length which essentially corresponds to the change in length of the copper tube occurring as a result of the drawing and, finally, the rod produced is sawn up into the desired rod lengths at the points where the copper cores are located.</p> |
