It is well known that amorphous metal materials having various shapes such as a ribbon shape, a filament shape, and a granular shape can be obtained. Amorphous metal ribbons can be easily manufactured by methods such as the one-roll method and the twin-roll method.
Numerous amorphous metal ribbons have been obtained for alloys of the Ni, Ni, Co, Pd, Ti, Cu or Zr alloys. Among them, the Ni-Si-B system amorphous metal ribbon is excellent in corrosion resistance and heat embrittlement and has a low Curie point, so it is paramagnetic at room temperature. It has unique properties such as the ability to obtain materials with a low temperature coefficient of resistance.

晶質金属フィラメントが必要とされていた。The Ni-Si-B system amorphous metal filament is required to avoid the influence of a magnetic field by utilizing the unique characteristics of the Ni-Si-B system amorphous metal material described above. It has been proposed to apply it to a strength material of a certain portion (for example, a dot wire of a dot printer, a covering strength material for electric wires). However, JP-A-62-1
Ni-Si-B based amorphous metal filaments disclosed in Japanese Patent No. 57923 were manufactured and their characteristics were examined. The strength of the rapidly solidified material was about 280 kgf / mm 2 at the maximum, and it was suitable for the above applications. It did not reach the required strength. Further, the heat resistance is also poor, and if it is kept at 350 ° C. for 10 minutes, it becomes brittle to the point that it cannot be practically used, and it cannot be applied to the above-mentioned applications including the heat treatment step. Therefore, there is a need for a paramagnetic amorphous metal filament having higher strength and excellent heat embrittlement as compared with the filament disclosed in JP-A-62-57923.

られにくくなる傾向がある。The amorphous metal filament of the present invention can be obtained by melting an alloy having the above composition and cooling and solidifying it in a cooling liquid. There are various methods for solidifying, and a preferable method is, for example,
JP-A-56-165016 or JP-A-57-7
The so-called rotating submerged spinning method described in Japanese Patent No. 9052 is mentioned. This method puts the cooling body in the rotating drum,
A cooling body film is formed on the inner wall of the drum by centrifugal force, and the alloy having the above composition melted in the cooling body film is spouted from the spinning nozzle to cool and solidify. In order to obtain a continuous thin wire with less heat, the peripheral speed of the rotating drum should be 5 to more than the speed of the molten metal flow ejected from the spinning nozzle
It is preferable to make it 30% faster, and to set the angle between the molten metal flow ejected from the spinning nozzle and the cooling body film formed on the inner wall of the drum to 20 to 70 °. The hole diameter of the spinning nozzle is 50 to 200 μm, especially 80 to 180 μmφ
Is preferred. If the pore size is less than 50 μm, it is difficult for the molten metal to be ejected from the nozzle, and it is difficult to obtain a quenched wire rod. On the other hand, when it exceeds 200 μm, the roundness tends to be low, the wire diameter unevenness becomes large, and it tends to be difficult to obtain a high-quality filament.

In this conveyor method, molten metal is spouted from a spinning nozzle and brought into contact with a cooling liquid layer formed on a running grooved conveyor belt for rapid cooling and solidification. In order to obtain a continuous metal filament according to the present invention with few spots, the velocity of the traveling cooling liquid on the conveyor is 300 m / min or more, and the velocity ratio between the molten metal jet and the traveling cooling liquid exceeds 1 to 1.3. It is desirable to accelerate the running cooling liquid at the following ratio, to make its contact angle larger than 30 °, and to make the spinning nozzle hole diameter 0.2 mmφ or less.
