TWI264469B - Copper-nickel-alloy and production method for its container - Google Patents

Abstract

For the production of vessels receiving metallic fusion, for example, a melting-pot for melting-and re-melting equipment, a material is necessary, said material has an excellent solderability in addition to an advantageous thermo-mechanical property. In this invention, a copper-alloy is not in a hardened state for this application, which is composed of: 0.2 to 1,55 nickel; 0, 002 to 0.12% at least one element from the group containing phosphor, aluminium, magnesium, lithium, calcium, silicium and boron; and the rest copper including production-related contaminant. In order to suitably increase the strength, the copper-alloy can contain until to 0.3% zirconium.

If-f,,:ri - — . __ _____ 乂. .___ J V. Description of the Invention (1) One aspect of the present invention relates to the use of a copper alloy as a material in a non-precipitation hardened state to manufacture a container for containing a metal melt, For example, vortexes for melt and non-melt equipment. Another aspect of the invention is directed to a method of making a container of a metal melt which is constructed of a copper-nickel alloy. Melt and non-melt processes are well known in practice. Designed to improve the quality of steel, and superalloys based on iron, nickel or cobalt. Yet another range of applications is in the manufacture of non-ferrous metals such as molybdenum, titanium, molybdenum or zirconium. The materials used to make 355 are usually copper and copper alloys with high thermal conductivity. Seamlessly welded or otherwise mounted 坩埚, usually in the form of a circular tube or square. In addition, there may be a polygonal or square basic pattern. Thus, individual applications may be of a type that is suitable for completing the final version of the component, such as a curved wave or pressure vessel. Containers containing metal melt, such as crucibles, have a typical length of up to 4 meters and a diameter of up to 1.5 meters. In melt and non-melt equipment, the crucible is in principle surrounded by a cooling jacket for introducing process heat. The cooling sleeve itself is of a steel construction, and may also be configured to integrate the cooling water guide into the copper alloy wall in the form of a slit or a cooling hole. A copper alloy is known from US Pat. No. 2 1 5 5 40 5 and contains 0. 25-3% nickel, 0.05-0.6 phosphorus, the balance being copper. This is the alloy of the conductive iridium preset. It has conductivity of 67% I ACS and high tensile strength. 1264469 xf, I Q t|

</ br> (4) 修 (家) jL本J. 5. Description of the invention (2) A precipitation hardenable copper alloy is known from EP-A1-o-249,740, which consists of 0.2-1.2% nickel and 0.04 - 0.25% phosphorus. This alloy can be applied to continuous casting of the material to continuously cast high melting point metals. Based on a few hours of precipitation hardening treatment, the material can achieve a hardness of 2.5/62.5 over 1 15 〇. The object of the invention is to provide a material suitable for use in the incorporation of melt and non-melt equipment, in addition to the required thermomechanical In addition to the characteristics, it has outstanding weldability. On the other hand, a suitable method for forming a container for a metal melt composed of a plurality of components as needed is provided. The solution to this object is, on the one hand, the use of a copper alloy comprising 0.2-1.5% nickel, 0.002-0.12% being selected from at least one element comprising phosphorus, Ming, Meng, Li, 15, magnesium, sand, boron groups, The Daxie 3% pin is used, and the rest is an impurity containing copper depending on the manufacturing conditions, and as a material, a non-precipitation hardening state is used to manufacture a container for accommodating the metal melt, such as a melt and a non-melt device. Preferably, the alloy used in the present invention contains 0.6-1.3% nickel, and 6%.〇 u. Q6% is selected from at least one element comprising a group of boron, magnesium and phosphorus, the basis being impurities comprising copper depending on the production. In order to improve the strength, the alloy should be introduced from 0. 01 to the top 0.3% pin. The solution to the method part of the object of the present invention is listed in items 5 to 6 of the patent application.
