<p>The invention relates to starting cathodes made of copper band for copper electrolysis and a method for the production thereof. Based on the disadvantages concerning the prior art, the aim of the invention is to produce starting cathodes which eliminate a memory effect during copper electrolysis, with which a high production capacity on electrolytic copper can be obtained, and which can also be produced from directly shaped copper band material provided in the shape of a coil. In addition, the invention provides a suitable method for producing the starting cathodes which is also especially suited for processing conventionally produced copper band. The inventive starting cathodes are comprised of rolled copper band which has a thickness ranging from 0.3 to 1.2 mm, which is soft annealed after rolling and which has a strength ranging from 210 to 240 N/mm2. The copper band is cut to a length and width defined by the dimensions of the electrolytic bath and comprises a surface which is planar, has few ridges and is free of grease. Lug strips made of copper band having a thickness ranging from 0.3 to 0.6 mm are fastened to the securing side of the steel sheets.</p> |
