（従来技術と間層点）
従来、高電気抵抗で軟磁性を示す材料は金属高透磁率材
料の中で１６％Ａ １− Ｆ ｅ合金が１４０μΩｌで
最高である。しかし、前記材料は脆いため冷間加工が困
難であり、冷間加工をするためには真空溶解と特殊な熱
間圧延を必要とする。 加工性が良く、高電気抵抗で軟
磁性を示す材料は少ない。(Prior art and interlayer points) Conventionally, among metal materials with high magnetic permeability, 16% A 1-Fe alloy is the highest material exhibiting soft magnetism with high electric resistance at 140 μΩl. However, the material is brittle and difficult to cold-work, and cold-working requires vacuum melting and special hot rolling. There are few materials that have good processability, high electrical resistance, and soft magnetism.
発明者等は電熱材料として活用され高い電気抵抗をもつ
Ｆｅ−Ｃｒ−Ａ２合金に着目し軟磁性材料について鋭意
研究を進めた。The inventors focused on Fe-Cr-A2 alloy, which is used as an electric heating material and has high electrical resistance, and conducted intensive research on soft magnetic materials.

グ現象が増加し。Since the heating wire for fine wires is made of a Fe-Cr-Al gold alloy high alloy, it is manufactured by repeating intermediate annealing and wire drawing. The magnetic properties after final annealing showed soft magnetism with only a slightly low magnetic flux density. However, as shown in FIG. 4, as the crystal grains become finer during wire drawing, they become textured and the pinning phenomenon of domain walls increases.
結果的に第３図のように保磁力が増加してしまう。As a result, the coercive force increases as shown in FIG.
そのため磁気特性向上のための熱処理が必要不可欠であ

The purpose of the present invention is to provide a soft magnetic wire with high electrical resistance, which is rare among metal high magnetic permeability materials, by using a manufacturing method in which Qf4 molten metal is jetted into a liquid through a spinning nozzle, thereby omitting a heat treatment step.

線である。 Ｃｒ含有量を多くすることにより耐蝕性、
又第１図のように電気比抵抗を高くすることができる。(Means for solving the problem) The first invention of the present invention provides Cr13 heavy visibility% to 30 heavy visibility%,
It is a high electrical resistance soft magnetic wire with a wire diameter of 0.5a or less, consisting of 2% by weight to 10% by weight of Al, the balance being Fe and unavoidable impurities. Corrosion resistance by increasing Cr content,
Furthermore, as shown in FIG. 1, the electrical resistivity can be increased.
Ｃｒが１３重量％未満では所定の電気比抵抗が得られず
、３０重量％を超えると加工性が劣化する。If Cr is less than 13% by weight, a predetermined electrical resistivity cannot be obtained, and if it exceeds 30% by weight, workability deteriorates.
Ａｌは電気比抵抗を上げ第２図のように保磁力を低下さ
せるために添加される。Ａｌが２重量％未満の場合は電
気比抵抗が低く保磁力が上がり。Al is added to increase the electrical resistivity and reduce the coercive force as shown in FIG. When Al is less than 2% by weight, the electrical resistivity is low and the coercive force is high.
１０重量％をこえると加工性が悪化する。If it exceeds 10% by weight, processability will deteriorate.
線径が０．５ｍを超える場合は断面積の増加に伴い熱容
量が増すため有効な冷却速度が得られないため正常な細
線が得られにくくなる。好ましくは０．３ｍ＋以下であ
る。If the wire diameter exceeds 0.5 m, the heat capacity increases as the cross-sectional area increases, making it impossible to obtain an effective cooling rate and making it difficult to obtain a normal fine wire. Preferably it is 0.3 m+ or less.
第４図に示すように伸線加工材は結晶粒が微細化、集合
組織であるが、本発明の金属組織は第４図に示すように
第５図の伸線加工後焼鈍処理した材料の金属組織とほぼ
同じような結晶粒の大きい組織になっている。As shown in Fig. 4, the wire-drawn material has fine grains and a textured texture, but the metal structure of the present invention is as shown in Fig. 5 of the wire-drawn and then annealed material. It has a structure with large crystal grains that is almost the same as a metal structure.

This nozzle diameter is made close to the desired diameter of the high resistance soft magnetic wire. The heating furnace 5 heats and melts the raw metal 3 to be melt-spun, and contains a cooling liquid 8 that forms a cooling liquid surface 9 inside a rotating body 6 rotated by a drive motor 7 by rotational centrifugal force. The pipe IO is for supplying and discharging the cooling liquid 8. The introduction angle between the molten metal 4 and the coolant surface 9 and the rotation of the rotating body 6 may be in any direction. In particular, the speed ratio (=rotational speed of the rotating body/spout speed from the nozzle), the distance between the spinning nozzle 2 and the coolant level 9, the introduction angle, etc. are important factors for producing a uniform continuous thin wire. The speed ratio is 105 to 130, and the distance between the spinning nozzle 2 and the cooling liquid level 9 is 10 m or less, preferably 3 m =
