Definitions

  • the invention is therefore based on the object of a casting process for excretory and / or tension sensitive and / or to indicate copper alloys sensitive to segregation, in which if it is precipitating copper alloys, the formation of the excretions completely suppressed or only in the form of very fine dispersions without further treatment is achieved, and in terms of voltage sensitive Copper alloys largely build up residual stresses is avoided and in so far as it is sensitive to segregation Alloys, the occurrence of segregations is weakened to the extent that the alloys can be cold worked directly become.
  • the object is achieved by the characterizing features of claim 1.
  • the rate of solidification is to be understood as the average rate at which the crystallization front progresses into the liquid phase.
  • the rate of solidification occurs in the case of the invention Process by determining a suitable casting thickness, whereby Materials with higher thermal conductivity, the casting of thicker Bands in the upper thickness range according to the invention allow at Lower thermal conductivity is preferred at the lower end the band thickness worked.
  • Another possible setting parameter is the cooling effect over the amount of water applied.
  • For copper alloys with medium thermal conductivity (10 - 80 W / mK) is preferably a strand in the thickness range of 1-5 mm poured. It is recommended, especially in the case of excretion and segregation sensitive alloys a solidification rate x ° of 6 - 8 mm / s must be observed.
  • the melt is either fed onto the deflection roller of the belt in positions between the 9 and 12 o'clock position or on the cooler belt stretched between the two transport rollers.
  • the invention is based on the following embodiment explained in more detail. It shows
  • Fig. 1 shows schematically a casting device for continuous Production of a near-net-length metal strand 1 of thickness D.
  • the metal melt 3 present in a distributor 2 is about a channel 4 from above on an endless cooling belt 5 made of metal given that revolves over pulleys 6, 7.
  • the metal band 5 is intensively cooled from the underside (see section 8 designated water nozzles). Due to the intensive cooling a rapid heat removal achieved in connection with the other process parameters to achieve a high solidification rate leads.
  • the casting structure is that made according to the invention Band shown at 50x magnification.
  • a strand 1 made of the alloy CuNi6Sn6 in a thickness D of 6.5 mm and a width of 150 mm was at a casting speed poured from 12 m / min.
  • Fig. 4th represents (also 1000x magnification). It is very here to recognize large areas in which the structure is a multi-phase Has structure. In these darkly striped structural areas the mean tin content compared to the environment is around 5 % By weight raised. So these are segregations, which have solidified in the form of a eutectic. This structure has a very limited formability in both heat as well as at low temperatures.
