Definitions

  • the invention relates to the use of a copper alloy as a material, in the non-hardened condition, for producing containers for holding metallic melts, such as crucibles for melting and remelting installations. More particularly, the invention is directed towards producing containers made of copper-nickel alloy which can hold melts.
  • melt and remelting processes are known from practical use. They are applied in order to improve the quality of steels and superalloys based on iron, nickel or cobalt.
  • a further application area is the production of nonferrous metals, such as tantalum, titanium, molybdenum or zirconium.
  • Seamless, welded or otherwise assembled crucibles usually have a round tube-shaped or rectangular basic design. However, those of polygonal or square basic design are also applied. Beyond that, occasionally shapes are used which are adapted to the final shape of the component to be produced, for example, for crankshafts and pressure containers.
  • Containers taking up metallic melts usually have lengths up to as much as 4 m and diameters up to 1.5 m.
  • the crucibles are surrounded by a cooling jacket used to dissipate the process heat.
  • the cooling jacket itself can be constructed of steel. But apart from that, designs are conceivable in which the conduction of the cooling water is integrated directly into the walls of the copper crucible in the form of slots or cooling borings.
  • a hardenable copper alloy which includes 0.2 to 1.2% nickel and 0.04 to 0.25% phosphorus. This alloy is for use as material for producing continuous casting molds for continuous casting of high melting point metals. After an age-hardening process of several hours, this material reaches a hardness HB 2.5/62.5 of more than 115.
  • the alloy to be used according to the invention contains 0.6 to 1.3% nickel and 0.01 to 0.06% of at least one element of the group including boron, magnesium and phosphorus, the balance being copper and impurities resulting from the production process.
  • the copper alloy contains 1.0 to 1.3% nickel and 0.01 to 0.03% phosphorus.
  • the alloy after a hot forming process, is cooled in still environmental air.
  • the alloy, after the hot forming process is cold formed by at least 10%.
  • the cold forming and a subsequent welding of the alloy at hand in the hot formed condition are adjusted to each other in such a way that the strength and the electrical conductivity in the welding seam do not deviate by more than 15% from the corresponding property values of the basic material.
