Definitions

  • the invention relates to a casting method according to the preamble of claim 1.
  • the invention is therefore based on the object of specifying a casting process for precipitation-forming and / or stress-sensitive and / or segregation-sensitive copper alloys, in which, if it is a matter of precipitation-forming copper alloys, the formation of the precipitations is suppressed entirely or only in the form of very fine dispersions without further Aftertreatment is achieved, and in the case of the stress-sensitive copper alloys, the build-up of residual stresses is largely avoided and, in the case of alloys sensitive to segregation, the occurrence of segregations is weakened to such an extent that the alloys can be cold-formed directly.
  • the rate of solidification is to be understood as the average rate at which the crystallization front progresses into the liquid phase.
  • the definition of a cooling rate in the liquid-solid phase mixture cannot accurately describe this setting and its permanent maintenance.
  • the casting method according to the invention allows a targeted method of operation.
  • the setting of the necessary solidification rate is carried out by specifying a suitable casting thickness, materials with higher thermal conductivity allowing casting of thicker strips in the upper thickness range according to the invention, with lower thermal conductivity, work is preferably carried out at the lower end of the strip thickness.
  • Further possible setting parameters are the cooling effect via the amount of water applied and the pouring speed.
  • a strand in the thickness range of 1 - 5 mm is preferably cast.
  • the high solidification rate is preferably achieved by pouring the melt onto a rotating, intensely cooled metal strip. The melt is fed either onto the deflection roller of the belt in positions between the 9 and 12 o'clock position
  • FIG. 1 schematically shows a casting device for the continuous production of a metal strand 1 of thickness D close to the final dimension.
  • the metal melt 3 present in a distributor 2 is fed via a channel 4 from above onto an endless cooling belt 5 made of metal, which rotates via deflection rollers 6, 7.
  • the metal strip 5 is cooled intensively from the underside (cf. the water nozzles labeled 8). Due to the intensive cooling, rapid heat removal is achieved, which in conjunction with the other process parameters leads to the achievement of a high solidification rate.
  • Fig. 2 the casting structure of the tape manufactured according to the invention is shown at 50 times magnification. Although a fine dendrite structure can still be seen, the dendrite arm spacing has dropped to 1/5 of the value for conventional casting, and the grain boundaries are also free of precipitation.
  • a strand 1 made of the alloy CuNi6Sn6 in a thickness D of 6.5 mm and a width of 150 mm was cast at a casting speed of 12 m / min.
  • the material After milling 0.5 mm of the thickness from the top and bottom of the cast strip, the material could be cold rolled by 87% without any edge cracks or other rolling defects.
  • the structure of the cast tape is shown in FIG. 3 at 1000 times magnification. There are minor excretions, but they do not affect the formability.
  • FIG. 4 also 1000-fold magnification.
  • Very large areas can be seen here in which the structure has a multi-phase structure. In these dark-streaked areas, the mean tin content is increased by about 5% by weight compared to the environment. So these are segregations that have solidified in the form of a eutectic.
  • This structure has a very limited formability both in the heat and at low temperatures.
