Definitions

  • the invention relates to the use of a hardenable copper alloy for molds, in particular for the production of broad side plates for thin slab casting molds
  • mold wide side plates for thin slab systems and in particular for CSP (compact strip product) systems are produced from copper alloys such as CuCrZr (copper chromium zirconium) or CuAg (copper silver). Because of this, a CuAg alloy for CSP mold plates has been produced comparatively high elongation with increasing temperatures has proven to be advantageous
  • mold wide side plates made of CuAg or CuCrZr are not able to absorb the high temperature tensions in the bath level of the cast metal and tend to form cracks in the area in this area, whereby CuCrZr in particular tends to form cracks particularly early. This crack formation is then the failure point for the mold wide side plates and causes high repair and replacement costs for the operator of a continuous caster
  • the failure rate of the narrow side plates is not the formation of cracks, but rather the wear or abrasion of the contact surfaces to the steel.
  • the most common failure criterion of the wide side plates is crack formation in the area of the mold level
  • Document DE 31 20 978 C2 discloses a number of precipitation-hardenable copper alloys and their use for stationary continuous casting molds, inter alia with various CuNiBe alloys, which, as further alloy components, include niobium (Nb), zirconium (Zr), magnesium (Mg) and / or titanium (Ti ) contain
  • a copper alloy CuZrNiBe is known from document US Pat. No. 2,137,281 for a strip mold (twin-belt casting) which is characterized by a combination of properties of comparatively great hardness with comparatively high thermal conductivity
  • the invention has for its object to provide a suitable for the production of broad side plates for thin slab casting molds with high casting speed in a special way suitable copper alloys, by their use in the casting operation early cracking, especially in the area of the mold level, avoided and Wear of the contact surface with liquid steel is reduced, and which withstands the extremely high thermal and mechanical stresses in the casting operation with long-term availability
  • the solution to this problem consists in the use of a hardenable copper alloy with a beryllium content of 0.1% to 0.5% and a nickel content of 0.5% to 2.0% (CuNiBe) for the production of broad side plates for thin slab casting molds
  • this copper alloy After hardening, this copper alloy has the great advantage of being able to absorb high temperature stresses in the area of the mold level while avoiding crack formation and to remain available over longer operating times
  • the copper alloy CuNiBe used according to the invention is helped by this advantageous operating result due to its advantageous material properties, for example a much higher tensile strength of approx. 770 or approx. 650 N / mm 2 and 0.2 proof strength of approx 500 N / mm 2 both at 20 ° C and at 300 ° C
  • the material properties of three selected copper alloys, CuCrZr, CuAg and CuNiBe are shown in the following table Material properties
  • Another positive property e.g. resistance to mechanical wear, results from the high hardness of the material used according to the invention of approximately 220 HB, because CuNiBe has approximately the same hardness as a galvanically applied nickel layer with approximately 220-230 HB.
  • the broad side plates therefore need can no longer be nickel-plated
  • the lower thermal conductivity of the copper alloy CuNiBe of approx. 300 W / mK compared to CuAg with a thermal conductivity of approx. 370 W / mK, can be compensated for by a reduced copper wall thickness of approx. 25% before water. This also results in a saving in material costs for the production
  • the invention enables the casting of thin slabs at high casting speeds of at least 2 to 6 m / min and more.
  • the significant improvement in the operating behavior as a result of longer availability, in particular the minimized one Cracking in the area of the bathroom mirror, the cost-effective expenditure for material and production are the result of the special selection of the alloy components
