Definitions

  • the invention relates to starting cathodes made of copper tape for copper electrolysis as well a process for the production of the starting cathodes.
  • the invention had for its object to provide starting cathodes made of copper strip for copper electrolysis, which exclude a "memory effect" during copper electrolysis, with which a high production output of electrolytic copper can be achieved and which can also be produced from directly deformed copper strip material present as a coil are. Furthermore, a suitable method for the production of the starting cathodes is to be created, which is also particularly suitable for processing conventionally produced copper strip.
  • the frequency of short circuits could be reduced considerably and current yields of 98 to 99% were achieved.
  • the thickness of the copper band for the ear strips could also be reduced to preferably 0.3 to 0.5 mm.
  • the specified strength of the copper strip of 210 to 240 N / mm 2 is achieved, for example, by post-treatment on a skin pass mill.
  • the hard-rolled copper strip is soft-annealed at furnace temperatures of 700 to 750 ° C, preferably at 720 to 750 ° C, the furnace temperature being reduced from 750 ° C to 720 ° C in the direction of flow.
  • the throughput speed of the copper strip essentially depends on the strip width and the strip thickness. For starter sheets for starting cathodes with a width of 930 mm and a thickness of 0.3 to 0.8 mm, this is 20 to 55 m / min.
  • the copper strip can be produced in a conventional casting and rolling plant and wound up as a coil. The hard-rolled copper strip is then unwound in a separate system, soft annealed in an annealing furnace, treated in a subsequent degreasing and pickling unit (scale and oxide removal) and straightened in a straightening and dividing system and cut to the required length of 840 to 1250 mm.
  • the starting cathodes are separated, sorted and hung in the prepared receptacle for the crane for hanging in the electrolysis bath. It is of considerable advantage that no separate special system for producing the starter plates is required, but that a hard-rolled copper strip is produced which is known per se and which can also be obtained from a third party. This also applies to a further variant, according to which the hard-rolled copper strip is soft-annealed within the casting and rolling plant and is available as a soft-annealed copper strip in the form of a coiled coil for further processing into starting cathodes.
  • the soft annealing of the rolled copper strip can be carried out in a vertical or horizontal type annealing furnace. Before soft annealing, the copper strip should be degreased, brushed, rinsed with water and dried. After the annealing, it is advisable to pickle and neutralize the cooled copper strip.
  • SF-Cu was rolled on a conventional casting and rolling machine to a copper strip with a width of 930 mm and a thickness of 0.5 mm.
  • the hard-rolled copper strip has a tensile strength of 263 N / mm 2 and is available as a coiled coil.
  • Starting cathodes are manufactured under the following conditions in a separate system, consisting of a decoiler, annealing furnace, degreasing and pickling unit, straightening and compartment system as well as the assembly system for the ears and contact bars.
  • the unreeled, hard-rolled copper strip passes through a horizontal suspension belt furnace, the heating zones of which are set to temperatures in the range from 750 to 720 ° C.
  • the belt speed is 35 m / min.
  • Soft annealing takes place in a protective gas atmosphere.
  • the soft annealed, cooled copper strip has a tensile strength of 217 N / mm 2 .
  • the degreasing and pickling unit also removes scale and oxide.
  • the copper strip is cut into lengths of 970 mm and the starter plates 970 x 930 mm thus obtained are straightened.
  • starter sheets which are to be further assembled are completely flat and smooth, have no external damage, such as scratches, and are free of grease, emulsions and oil.
  • the dry, clean starter sheets are transported to a riveting machine to attach the necessary ear strips, which are made from 0.4 mm thick copper tape, which is made from the same type of material as the starter sheets. After attaching the "ears" to the starter plates, the contact rods are attached.
  • hard-rolled copper strip is produced from SF-Cu and coiled as a coil.
  • the 930 mm wide, hard-rolled copper strip has a thickness of 0.635 mm after the rolling process.
  • the copper strip is degreased, brushed, rinsed with clear water and dried.
  • the hard-rolled copper strip then runs through a floating belt furnace at a speed of 27.5 m / min, the furnace temperatures are in the range from 750 to 720 ° C.
  • the cooled copper strip has a tensile strength of 217 N / mm 2 . It is then pickled, neutralized, reeled up as a coil and stored temporarily.
  • the soft-annealed copper strip which is in the form of a coil, is unwound in a separate system and further processed into starting cathodes in a straightening and compartment system, as well as in the assembly system for the ears and contact rods, as in Example 1.
  • the sheet thickness of the ears attached to the starter cathodes is 0.5 mm.
  • Starting cathodes are produced analogously to Example 1, with the only difference that the casting and rolling system, the annealing furnace, the degreasing and pickling unit, the straightening and compartment system and the packaging system are arranged in one line. This eliminates the need to rewind and unwind the hard-rolled or soft-annealed copper strip according to Example 1 or Example 2.
  • the copper strip material consists of SF-Cu and is reduced to a thickness of 0.8 mm by the rolling process.
  • the temperatures in the suspension belt furnace are also 750 to 720 ° C, the throughput speed is 23 m / min.
  • the soft-annealed, cooled copper strip has a tensile strength of 232 N / mm 2 .
  • the dimensions of the starter plates are also 970 x 930 mm.
  • the ears riveted to the starter plates have a thickness of 0.6 mm.
  • the starting cathodes produced according to the above examples were used for electrolysis experiments and have the following parameters: Starting cathodes 970 x 930 mm made of SF-Cu S1 S2 S3 S4 Sheet thickness mm 0.5 0.635 0.8 0.5 Tensile strength N / mm 2 217 217 232 263 Ear thickness mm 0.4 0.5 0.6 0.4 annealed Yes Yes Yes No
