本発明は、機械、器具等の導体等として曲用きれる刹1
1物Cu−Cr系合金線の製造方法に関するものである
。[Detailed description of the invention] (Technical field) The present invention can be used as a conductor for machines, appliances, etc.
The present invention relates to a method for manufacturing a one-component Cu-Cr alloy wire.
(背景技術)
近年、電気機器、電子機器の小型化に伴ない電線導体に
ふ・いても細線化が進行しつつある。(Background Art) In recent years, with the miniaturization of electrical and electronic devices, wire conductors have also become thinner.
このため導体にはより高強度かつ耐屈曲特性に優されて
きた。その一つとしてCu−Cr合金線と、弓°った時
効硬化型銅合金線等が倹8]され、実用されている。For this reason, conductors have been improved in strength and bending resistance. As one of these, Cu-Cr alloy wire and curved age-hardening copper alloy wire have been developed and put into practical use.
しかし、Cu−Cr合金線は銅線に比べて焼入れ処理を
必要とする他、加工性が良くないので、絹物線の製造に
は多数の工程を必要とした。However, compared to copper wire, Cu-Cr alloy wire requires quenching treatment and has poor workability, so a large number of steps are required to manufacture silk wire.
第1図(イ)は0.05〜0.1 mmΦ程度のCu
−Cr合金線の製造工程の例を示す工程図である。図に
示すように、従来インゴット鋳造、圧延、熱処理(溶体
化焼入れ処理)、伸線、軟化(時効)処理等の多数の工
程を経て製造されていた。Figure 1 (a) shows Cu of about 0.05 to 0.1 mmΦ.
It is a process diagram showing an example of a manufacturing process of a -Cr alloy wire. As shown in the figure, conventional wires have been manufactured through a number of steps such as ingot casting, rolling, heat treatment (solution heat treatment), wire drawing, and softening (aging) treatment.

要としたため、伸線加工性が悪く、断線、傷等による歩
留りの低下、上述の溶体化焼入れ処理等の工程増加によ
り製造コストが高くなる欠点があった。In this case, Cr is likely to segregate during casting and cause casting defects, Cr oxides are likely to be generated during melting, Cr oxides are likely to be involved during casting, the surface during solution hardening is likely to oxidize, and ultra-fine wires are likely to occur. Because a large degree of cold working is required to draw the wire, the wire drawability is poor, the yield decreases due to wire breakage, scratches, etc., and the production cost increases due to the additional steps such as the solution quenching treatment mentioned above. there were.
(発明の開示)
本発明は、上述の欠点を解消するため成されたもので、
製造工程を極度に簡素化して、設備費、王が容易で欠陥

する方法を提供せんとするものである。(Disclosure of the Invention) The present invention has been made in order to eliminate the above-mentioned drawbacks.
It is an object of the present invention to provide a method of manufacturing a thin Cu--Cr alloy wire with excellent characteristics by extremely simplifying the manufacturing process, reducing equipment costs, easy maintenance, and having few defects.

線の製造方法である。The present invention produces a fine long ingot by ejecting a Cu-Cr alloy containing 2 to 15% of CrO and mainly consisting of CO from a molten state into a liquid fluid through pores or slits. This is a method for manufacturing a thin Cu-Cr alloy wire.
本発明において、Cu−Cr系合金とは、Cr02〜1

It is a copper alloy containing 5% of copper as a main component, and in addition to Cr, it also contains Ag, Sn, Mg, Al1. It may contain 0.5% or less of each of one or more elements selected from the group consisting of Be, P, and L'i.
本発明により製造される細物Cu −Cr系合金線は、

。In the present invention, Cr in the alloy reduces the loss of electrical conductivity, improves softening resistance and mechanical properties, and achieves both tensile strength and elongation properties. If it is less than 0.2%, the effect of improving mechanical properties when made into a silk wire is insufficient, and if it exceeds 1.5%, the improvement effect on the mechanical properties when made into a thin wire is insufficient. This is because the effect of improving mechanical properties is saturated, and the cost of raw materials is unnecessarily increased and the melting process becomes difficult.
以下、本発明を図面を用いて実施例により説明する。第

れ、特に制限はない。Hereinafter, the present invention will be explained by examples using the drawings. FIG. 1(B) is a diagram showing the manufacturing process of an embodiment of the method of the present invention. In the method of the present invention, a Cu-Cr alloy is melted,
By jetting the molten material into a liquid fluid through pores or slits, it is rapidly solidified into a long silk ingot and rapidly cooled. In this case, cooling to a temperature of 100° C. may be performed by various methods for solidification cooling of 500° C., and there is no particular restriction.

物長尺鋳塊8とされる。3は加圧ガス流入口である。After melting, the molten metal is constantly ejected from the nozzle 5 at the bottom of the crucible 2, and is injected into the laminar liquid fluid 7 existing inside the rotating drum 6, where it is rapidly solidified and then quenched to form silk into a length. It is said to be a shaku ingot 8. 3 is a pressurized gas inlet.

と得られた鋳塊としての線が脆くなり易い。In this case, the cooling rate until the temperature reaches 100°C after solidification is 500 to aooooo°C/sec. The purpose of setting such a cooling rate is to ensure the effect of the solution treatment while ensuring subsequent cold workability.If the cooling rate is less than 500°C/sec, the effect of the solution treatment tends to be insufficient. The effect of preventing segregation of Cr is also insufficient, and when the temperature exceeds 30,000° C./sec, the obtained wire as an ingot tends to become brittle.
