Definitions

  • the invention relates to the use of a copper alloy consisting of 0.2 to 1.2% nickel, 0.04 to 0.25% phosphorus, the rest copper and manufacturing-related impurities.
  • Copper predominantly of the SF-Cu type, has long been used as a material for the production of continuous casting molds for the continuous casting of refractory metals such as steel, which, due to its high thermal conductivity, can dissipate the heat from the melt very quickly.
  • the wall thickness of the molds is chosen so large that it sufficiently meets the mechanical loads to be expected.
  • the invention consists in the use of a copper alloy consisting of 0.2 to 1.2% nickel, 0.04 to 0.25% phosphorus, the rest copper and production-related impurities as a material for continuous casting molds.
  • the nickel content is preferably 0.3 to 0.5% and the phosphorus content 0.06 to 0.1%, the ratio of nickel to phosphorus being between 3.5 and 7 to 1, preferably 5: 1.
  • the material is characterized by particularly favorable mechanical and physical properties. It has a thermal conductivity that is around 80% of that of pure copper.
  • the values for heat resistance, creep resistance and hot plasticity are also in an extremely favorable range for continuous casting molds.
  • the Brinell hardness as a benchmark for abrasion resistance reaches values of over 100.
  • Another essential requirement for continuous casting molds is high corrosion resistance, which is achieved by the copper-nickel-phosphorus alloy.
  • the physical properties that are placed on a continuous casting mold are not only limited to the conductivity and tensile strength, but it also depends on properties that could not easily be derived from US Pat. No. 2,155,405. Since the melt in contact with the mold wall in the case of steel has a temperature of more than 1300 ° C - the melting point of copper or copper alloys is around 1100 °, so a high thermal conductivity is of course important. However, since the mold wall can reach a temperature of up to 450 ° C, the heat resistance is of crucial importance, i.e. the sharp drop in strength must be shifted to a temperature range which is above the use temperature of the mold.
  • the semi-hard temperature (recrystallization temperature) of the alloy used according to the invention is approximately 575 ° C.
  • Another important property of materials for continuous casting molds is the warm plasticity, which is determined by the elongation at break. A high elongation at break together with a high heat resistance leads to a material for continuous casting molds which shows only slight signs of wear and does not tend to crack under the thermal stresses in the area of the bath level. Finally, creep behavior at higher temperatures is an essential measure of the freedom from distortion.
  • a copper alloy with 0.43% nickel, 0.0801% phosphorus, the rest copper and manufacturing-related impurities was molded into a tube by extrusion after casting.
  • the tube was then solution annealed at 700 ° C for one hour. After solution annealing, one sample was cold worked by 10% and another sample by 20%. Both samples were then cured at 450 ° C for eight hours.
  • the alloy according to the teaching of the invention is less expensive to produce than a copper-chromium-zirconium alloy, since the solution annealing temperature is much lower than that of copper-chromium-zirconium and thus the risk of coarse grain formation and rejects is avoided.
  • the alloy partners in the alloy according to the invention are much cheaper.
  • the invention is of course not limited to the exemplary embodiment, but can also be used for molds of all types with which metallic mold strands can be produced in a semi-continuous or fully continuous manner, for example tubular molds, block molds of all types, casting wheels, casting roll jackets, etc.
