Name and Address of Applicant: Actual Inventor(s): Address for Service: Invention Title: KM Europa Metal Aktiengesellschaft Klosterstrasse 29 D-490740snabruck Germany Thomas Helmenkamp Dirk Rode Hans-Gunther Wobker Spruson Ferguson St Martins Tower,Level 31 Market Street Sydney NSW 2000 (CCN 3710000177) Use of a Copper-nickel Alloy The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845c Use of a copper-nickel alloy The invention concerns firstly the use of a copper alloy as a material in the non-precipitation hardened condition for the production of receptacles containing metallic melts, for example crucibles for smelting and refining plants.
S Secondly the invention is directed towards a process for manufacturing receptacles made of a copper-nickel alloy, the said receptacles being capable of containing metallic melts.
Smelting and refining processes are well-known in practice. They are used to improve the quality of steels and superalloys based on iron, nickel or cobalt. Another field of application is the manufacture of nonferrous metals, such as for example tantalum, titanium, molybdenum or zirconium Copper and copper alloys, which have a high thermal conductivity, generally are considered as materials suitable for the manufacture of crucibles.
S: The seamless, welded or other composite crucibles generally have a round tubular or rectangular basic shape. However, crucibles with a basic form such as a polygon or square also are used. In .4 addition, some shapes are occasionally used which are adapted to the finished form of the component being manufactured e.g. crankshafts and pressure vessels.
The receptacles containing metallic melts, such as for example crucibles, generally have lengths 2 of up to a maximum of 4 m and diameters up to 1.5 m.
In smelting and refining plants the crucibles as a rule are surrounded by a cooling jacket which is used to dissipate process heat. In that case, the cooling jacket itself can be designed as a steel structure. However, designs differing from that are also conceivable, in which the cooling water path is integrated directly into the walls of the copper crucible in the form of channels or cooling holes.
A copper alloy, which contains 0.25 to 3 of nickel, 0.05 to 0.6 of phosphorus, and the remainder being copper, is known from US-A-2 155 405. This alloy, which is intended for electrical conductors, has an electrical conductivity of 67 IACS (internal annealed copper /0 standard) and a relatively high tensile strength.
Furthermore, a treat-treatable copper alloy, which is comprised of 0.2 to 1.2 nickel and 0.04 to 0.25 phosphorus, is known from EP-A1-0 249 740. This alloy is to be used as a material for *ooo the manufacture of continuous casting permanent moulds for continuous casting of high melting oo..
point metals. Owing to a hardening treatment lasting several hours, this material achieves a hardness HB Brinell hardness) 2.5/62.5 of over 115.
The aim of this invention is to provide a material mainly for use as crucibles in smelting and refining plants and which, apart from good thermomechanical properties, has excellent weldability.
On the other hand, a suitable process for manufacturing a receptacle composed if necessary of )I several parts for metallic melts will be explained.
The solution to this problem consists, on the one hand, in using a copper alloy of 0.2 to 1.5 nickel, 0.002 to 0.12 at least of one element from the group containing phosphorus, aluminium, manganese, lithium, calcium, magnesium, silicon and boron, alternatively up to 0.3 of zirconium, the remainder being copper including impurities due to production conditions, Sas a material in the non-precipitation hardened condition for the production of receptacles containing metallic melts, for example crucibles for smelting and refining plants.
Preferably the alloy being used according to the invention contains 0.6 to 1.3 of nickel and 0.01 to 0.06 at least of one element from the group containing boron, magnesium and phosphorus, the remainder being copper including impurities due to production conditions.
i° For the aimed-for increase in strength, it is advantageous to add 0.01 up to a maximum of 0.3% of zirconium to the alloy.
*o Resolution of the procedural part of the task is finally looked at in the characteristics in Claims to 7.
