Definitions

  • the invention relates to the use of a hardenable copper alloy for the production of casting rolls and casting wheels, which are subject to changing temperature stresses during casting close to the final dimensions.
  • the lower electrical conductivity of a known CuNiBe alloy with an addition of up to 1% niobium also leads to a higher surface temperature compared to a CuCrZr alloy. Since the electrical conductivity is inversely proportional to the thermal conductivity, the surface temperature of a casting roll made of the CuNiBe alloy will be about 540 compared to a casting roll made of CuCrZr with a maximum temperature of 400 ° C on the surface and 30 ° C on the back Increase ° C.
  • Ternary CuNiBe or CuCoBe alloys generally have a Brinell hardness of over 200 HB, but the electrical conductivity of the standard semi-finished products made from these materials, such as rods for the production of resistance welding electrodes or sheets and strips for the production of springs or Lead frames, at most values in the range from 26 to about 32 m / ⁇ mm 2 . Under optimal conditions, these standard materials would only achieve a surface temperature of around 585 ° C for the casting roll.
  • the object of the present invention is to provide a material for the production of casting rolls, casting roll jackets and casting wheels, which is insensitive to changing temperature loads even at casting speeds of over 3.5 m / min, or which has high fatigue resistance at the working temperature which has casting rolls.
  • a hardenable copper alloy made of 1.0 to 2.6% nickel, 0.1 to 0.45% beryllium, the rest of copper including manufacturing-related impurities and usual processing additives, with a Brinell hardness of at least 200 HB and one has proven particularly suitable for this application electrical conductivity over 38 m / ⁇ mm 2 .
  • a further improvement in the mechanical properties, in particular an increase in the tensile strength, can advantageously be achieved by adding 0.05 to 0.25% zirconium.
  • Copper alloys according to the invention are preferred in which the ratio of the nickel content to the beryllium content with a nickel content of over 1.2% in the alloy composition is at least 5: 1.
  • alloys to be used according to the invention show how critical the composition is in order to achieve the desired combination of properties.
  • the composition of the example alloys is given in Table 1 in% by weight. The corresponding test results are summarized in Table 2.
  • Table 1 Leg. Ni Be Cu A 1.43 0.54 rest B 1.48 0.40 rest C. 1.83 0.42 rest D 2.12 0.53 rest F 1.48 0.29 rest G 1.86 0.33 rest H 1.95 0.30 rest K 2.26 0.35 rest Leg.
  • Table 2 shows the hardness and conductivity values achieved for alloys with different nickel and beryllium contents - corresponding to different Ni / Be ratios. All of the alloys were melted in a vacuum furnace, hot-formed and, after solution annealing at 925 ° C. for at least one hour and subsequent quenching in water, hardened for 4 to 32 hours at a temperature in the range from 350 to 550 ° C.
  • the desired combination of properties can be achieved if the weight ratio of nickel to beryllium is at least 5: 1.
  • casting rolls or casting roll shells are subjected to an additional cold deformation of about 25% after solution annealing, a further improvement in the electrical conductivity can be achieved.
  • a 32-hour hardening treatment at 480 ° C achieves a conductivity of 43 m / ⁇ mm 2 and a Brinell hardness of 225 HB.
  • the properties can be further optimized by increasing the Ni / Be ratio.
  • a copper alloy with 2.26% nickel and a Ni / Be ratio of 6.5 has a Brinell hardness of 230 HB and an electrical conductivity of 40.5 m / ⁇ mm 2 after a 32-hour hardening treatment at 480 ° C.
  • a Ni / Be ratio of 7.5 is possible for a nickel content of 2.3% in order to achieve the desired combination of properties.
  • the sample alloy N was selected for the additional investigation of the fatigue behavior, since it has a relatively low electrical conductivity. With alloy N, a maximum surface temperature of around 490 ° C can be achieved for a casting roll. Under the previously known stress of a casting roller when casting steel, the service life of the alloy N to be used according to the invention is then increased by 2 to 3 times compared to a CuCrZr alloy. Due to the high Brinell hardness, there is also no risk that the surface of the casting roll will be damaged by the injection of melt spatter.
