いる。(To the prior art and its problems) Amorphous wire rods are being put into practical use as reinforcing materials and various sensors, and future demand is expected, and a practical technology to continuously manufacture ultrafine wires directly from molten metal is desired. It is rare.

)という欠点がある。As a method of obtaining a thin wire with a circular cross section directly from molten metal, the molten metal ejected from a nozzle is guided into a rotating body that forms a cooling liquid layer, cooled and solidified, and then continuously wound around the inner wall of the rotating body. There are methods (such as Japanese Patent Application Laid-open No. 165016/1983). However, this method always requires batch operation, making continuous production operation on an industrial scale extremely difficult.

また水層移動速度を大きくできないという欠点がある。This drawback is attributed to the method itself, in which a cooled liquid layer is pushed inside a rotating cylinder by centrifugal force, and then the cooled and solidified metal filament is continuously accumulated and wound around the inner wall of the rotating cylinder. A method has also been devised in which the cooling material is cooled by a belt-shaped cooling body using a jet nozzle or a grooved belt conveyor (Japanese Patent Application Laid-open Nos. 58-119440 and 1987-173059). In this method, it is very difficult to stabilize the cooling liquid layer.
Another drawback is that the water layer movement speed cannot be increased.

る。When obtaining a thin metal wire directly from molten metal, one of the important factors in terms of manufacturing conditions is to set the speed and change of the molten jet flow velocity Vj and drum circumferential velocity VD to appropriate values. V
When D/V; deviates from the optimum range and becomes smaller, a vertical line or irregularly shaped discontinuous line will be formed, or even if it becomes a continuous line, it will become distorted. On the other hand, if VD/Vj exceeds the optimum range and increases, it is difficult to obtain continuous thin wires, and only short fibrous wires can be obtained. For example, in the method described in JP-A-56-165016, in which the wire is continuously wound into a rotating body without being taken out, the formed thin wire is restrained on the inner surface of the drum, so it eventually solidifies. , the speed of the wire after cooling completely matches the peripheral speed of the drum. Although the fluctuation difference between the jet flow velocity and the drum peripheral speed can be absorbed by reducing the cross-sectional area of the solidifying molten metal jet flow, etc., it is considered that the conditions of VD/Vj to obtain a continuous long thin line are extremely narrow.

In this method, cooling water is supplied into the drum while rotating a cylindrical drum, and 1 m of cooling water is formed along the inner peripheral surface of the drum by centrifugal force, and the molten metal is poured into the cooling water layer through a nozzle. The metal coagulation wire is injected toward the drum, solidified, and guided by centrifugal force toward the outlet (water outlet), where the metal coagulation wire is continuously discharged into the cooling water and tub, and the fine metal wire is taken out of the drum. That is, the thin wires are discharged from the outlet along with the cooling water without being deposited on the inner surface of the drum.

。(Problem to be solved by the invention) In this method, after a certain run-up distance, the formed thin wire is released together with the cooling liquid without being restrained by the inner surface of the drum, so assimilation and cooling are not necessarily completed. The thin wire and drum peripheral speed do not match, that is, the motion behavior of the thin wire when cooling water enters is completely different from the first method.

A water layer is formed, and the molten metal is injected from inside the cooling water layer through a nozzle toward the cooling water layer to avoid solidification, and guided by centrifugal force toward the outlet, and from the outlet along with the cooling water. In a continuous manufacturing method for thin metal wire, in which the metal solidified wire is continuously discharged and the thin metal wire is taken out of the drum, the drum circumferential speed VD, the molten metal jet flow speed V
j, satisfies the relational expression between the angle θ between the molten metal jet entering the cooling water surface and the vertical line, and the angle ψ from the point where the molten metal jet lands on the cooling water surface to the position of the outlet It is characterized in that it is manufactured in this manner.

ことなく、極自然に取り出すことができる。(a) Manufacturing conditions Continuous manufacturing method of thin metal wire according to the present invention (JP-A-61-2
53147), as shown in Fig. 1, a cooling water layer 2 is formed along the inner peripheral surface of the drum by centrifugal force by supplying cooling water into the cylindrical drum 1 while rotating the drum. , the molten metal M is injected from inside the cooling water layer 2 through the nozzle 3 toward the lower cooling water layer 2, solidified, guided toward the outlet 14 by centrifugal force, and The metal coagulation wire W is continuously taken out of the drum l together with the cooling water. Mechanically, continuous extraction is difficult if extraction from the rotating drum is performed from the inside, but nozzle 3 injects molten metal onto the rotating drum that forms a cooling water layer.
By providing the take-out opening 14 opposite to the opening 14, the fine metal wire W solidified by the cooling water can be taken out quite naturally without resisting the external force applied thereto.

より、溶湯流に動圧がかかり、その流イtが乱される。In this method, when the molten metal ejected from the nozzle enters the liquid layer 2 at point A, the molten metal jet flow velocity Vj and the liquid J
Due to the difference of ~'DCO3θ in the ejection direction component of the velocity of i7i2, dynamic pressure is applied to the molten metal flow, and the flow t is disturbed.

し、運転が不可能になる。If this turbulence is small, there is no problem; the particles solidify in the liquid layer 2 and are discharged from the outlet 14 at a run-up distance from the inner surface of the tram. However, when the dynamic pressure is large, the disturbance becomes large, and the solidified line W is affected by the disturbance,
Instead of a straight line, it becomes a twisted line. If the degree of twist is large, resistance will be applied to the wires through the outlet 14, making it impossible to discharge the drum, and the wires will accumulate on the inner surface of the drum, making operation impossible.
本発明において、後に例を示すように、動圧の程度を決

可能となることを見いたした。In the present invention, as shown in an example later, the flow velocity V determines the degree of dynamic pressure, and the seven liquid layer velocity components V cos θ
It has been found that when the difference in Vj exceeds a certain ratio, release becomes impossible.

の助走距離りをおいたのち、拘束されないうちに取出口
I4より細線Wが放出される。In other words, when the approach angle is θ, it is sufficient that the following is satisfied.In addition, in this method, the molten metal jet ejected from the nozzle 3 enters the liquid layer 2 at point A, solidifies and cools. The thin wire W thus formed reaches the inner wall of the drum. Here, after a certain run-up distance along the inner wall of the drum, the thin wire W is discharged from the outlet I4 without being restrained.

角度ψによっである。この条件を満たさないと、すべり
摩擦によって生ずる力が大きくなり、その力をうけて細
線がきれてしまい連続線が得られなくなる。Therefore, the speed of the solidified and cooled thin wire W and the peripheral speed of the drum do not completely match. The force applied to the thin wire is the sliding friction between the thin wire and the drum caused by the speed difference, and its magnitude is proportional to the run-up section. In the present invention, as will be shown later, this is due to the angle ψ between the nozzle ejection position A and the outlet position B. If this condition is not met, the force generated by sliding friction will increase, and the thin wire will break due to this force, making it impossible to obtain a continuous line.

関数として見出し、数式化できた。From the above, it has been found that continuous thin wire can be stably extracted using the method disclosed in Japanese Patent Application Laid-Open No. 61-253148. That is, the conditions for stably extracting a continuous line were found and expressed mathematically by finding the lower and upper limits of VD/Vj as functions specific to the device.

When the molten metal M is injected from the drum, the molten metal M enters the cooling water layer, cools and solidifies, and at the same time is pulled away in the rotational direction of the cooling water and lands on the inner peripheral surface of the drum due to centrifugal force. The generated solidified fine wires proceed toward the outlet 14 on the sleeve)-shaped circumferential opening 13 with the cooling water, and are released by the centrifugal force of the cooling water due to the fluid pressure and themselves. Due to the acting centrifugal force, the water is discharged to the outside of the drum through the opening (takeout port) 14 between the water outlet pulleys.
