Definitions

  • the invention relates to the use of a hardenable copper alloy for the production of blocks for the side dams of double belt casting systems, in which the melt solidifies in the gap of two strips guided in parallel.
  • the side dams consist of metal blocks which are lined up on an endless belt, for example made of steel, and which move in the longitudinal direction synchronously with the casting belts.
  • the metallic dam blocks laterally delimit the mold cavity formed by the casting belts.
  • a hardenable copper alloy is described as a material for the blocks of side dams in US Pat. No. 3,955,615.
  • This alloy consisting of 1.5 to 2.5% nickel, 0.4 to 0.9% silicon, 0.1 to 0.5% chromium and 0.1 to 0.3% iron, the rest of copper, is usually used in double belt casting plants used for the continuous continuous casting of copper.
  • the side dam blocks made from this copper alloy tend to experience fatigue cracks in the area of the T-slot after a relatively short period of operation.
  • the alloy also has a relatively low electrical conductivity with about 35% IACS and thus also a too low thermal conductivity.
  • copper-based alloys containing beryllium are also unsuitable for the production of side dam blocks, since damage to health when machining or regrinding the blocks cannot be ruled out with certainty.
  • the object of the present invention is to provide a material for the production of casting molds which is insensitive to cracking under a thermal shock treatment and which also has a high heat resistance.
  • the solution to this problem according to the invention consists in the use of a hardenable copper alloy of 1.6 to 2.4% nickel, 0.5 to 0.8% silicon, 0.01 to 0.20% zirconium, the rest of copper including production-related impurities and more Processing additives as a material for the production of casting molds that are subject to permanent changing temperature stress, in particular blocks for the side dams of double belt casting plants.
  • a hardenable copper alloy of 1.6 to 2.4% nickel, 0.5 to 0.8% silicon, 0.01 to 0.20% zirconium, the rest of copper including production-related impurities and more Processing additives as a material for the production of casting molds that are subject to permanent changing temperature stress, in particular blocks for the side dams of double belt casting plants.
  • an addition of up to 0.4% chromium and - if necessary to reduce the grain growth during solution annealing - an iron addition of up to 0.2% is particularly advantageous.
  • the specific effect of the zirconium on the insensitivity of the copper material to crack formation is not adversely affected
  • Deoxidants such as boron, lithium, magnesium or phosphorus, up to a maximum of 0.03%, as well as usual manufacturing-related impurities also have no negative influence on the tendency to crack of the alloy to be used according to the invention.
  • a hardenable copper-nickel-silicon-zirconium alloy is already known from DE-OS 26 34 614, the composition of which consists of 1 to 5% nickel, 0.3 to 1.5% silicon, 0.05 to 0.35 % Zirconium, rest copper.
  • this known alloy is to be used for the production of objects which, in the hardenable state, must have increased toughness at room temperature.
  • the description shows that the effect of zirconium is particularly favorable if the material is subjected to a cold deformation of 10 to 40% between solution annealing and hardening.
  • zirconium in the merely hardened state and not cold-formed before hardening, practically eliminates the sensitivity to thermal shock of the known copper-nickel-silicon alloy. Additional studies also found that the heat resistance of the alloy to be used according to the invention at 500 ° C. significantly exceeds that of the materials previously used for the production of blocks of side dams.
  • alloys A, B, C Three alloys to be used according to the invention (alloys A, B, C) and three comparative alloys (alloys D, E, F) show how critical the composition of the respective example alloys is in order to achieve the desired combination of properties.
  • the composition of the example alloys is given in Table 1 in% by weight.
  • Alloys A and D were melted in a vacuum furnace, the remaining alloys were melted in air in a medium-frequency furnace, each cast into circular blocks with a diameter of 173 mm and extruded into rods of the format 55 ⁇ 55 mm. After solution annealing at 790 to 810 ° C, the bars were cured at 480 ° C for four hours.
  • the tensile strength R m at room temperature, the Brinell hardness HB (2.5 / 62.5), the electrical conductivity and the heat resistance (R m at 500 ° C.) were determined on the example alloys.
  • the thermal shock behavior was finally checked on blocks measuring 50 ⁇ 50 ⁇ 40 mm.
  • the blocks were first kept at 500 ° C. for two hours and then quenched in water at 25 ° C. It was usually possible to determine with the naked eye whether the blocks showed cracks or were free of cracks after the thermal shock test.
  • the T-slot of the blocks was checked with a microscope at 10x magnification. The extent of the cracks found, which all originated from the T-slot of the blocks, was mainly in the range from 1 to 7 mm, in individual cases the cracks even reached a length of over 20 mm.
  • the comparison shows that the alloys A, B and C to be used according to the invention have comparable strength properties at room temperature, both in terms of their electrical properties and, in particular, in terms of their heat resistance and thermal shock behavior, overall more favorable values than the comparative alloys D, E and F.
  • the copper alloy to be used according to the invention is therefore outstandingly suitable for all casting molds which are subject to a permanently changing temperature load during the casting process.
  • these are above all casting wheels and casting belts, as well as die casting molds and pressure pistons for die casting machines.
