本発明は細線製造装置に係り、特にノズルが改良された
細線製造装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thin wire manufacturing device, and more particularly to a thin wire manufacturing device with an improved nozzle.
従来、溶湯急冷法によシ細線を製造する場合には、石英
材によって構成された単孔のノズルを用い、該ノズルの
開孔から回転するロールの表面に溶湯を噴出させること
により行なっていた。このような方法で細線を製造する
場合、巾２００μｍ以上の線を製造する場合には特に問
題はないが、巾２００μｍ以下、特に１５０ ／Ｊｍ以
下の細線を製造する場合には、極めて不都合な問題が生
ずる。Conventionally, when manufacturing fine wire by the molten metal quenching method, a single-hole nozzle made of quartz material was used, and the molten metal was spouted from the opening of the nozzle onto the surface of a rotating roll. . When manufacturing thin wires using this method, there is no particular problem when manufacturing wires with a width of 200 μm or more, but when manufacturing thin wires with a width of 200 μm or less, especially 150/Jm or less, there are extremely inconvenient problems. occurs.
即ち、ノズルの開孔は内側直径１００μｍ程度の細いも
のにするため、ノズル孔はつまりやすく、従って、ノズ

の溶湯によって主にもたらされるのであるが、ノズル先
端の開孔部付近は極めて細い孔になっているので孔内の
溶湯のみでは十分な温度上昇及び温度保持が達成されな
いためと考えられた。That is, since the opening of the nozzle is made narrow with an inner diameter of about 100 μm, the nozzle hole is easily clogged. Therefore, the amount of molten metal that can be dispensed from the nozzle is limited to about 2 g, and even if you try to dispense more molten metal, Because the nozzle holes become clogged, work has to be interrupted. As a result of investigating the cause of such nozzle hole clogging, it was found that a drop in temperature at the nozzle tip was a contributing factor. That is,
Even when high-frequency induction heating is used in thin wire manufacturing equipment, the quartz that is the material of the nozzle does not generate heat, so the temperature increase and temperature maintenance at the nozzle tip is mainly brought about by the molten metal inside the nozzle. This is thought to be because the hole near the opening at the tip of the nozzle is extremely narrow, and therefore sufficient temperature rise and temperature maintenance cannot be achieved with the molten metal inside the hole alone.

となシ、良好な細線を製造することが困難となるのであ
る。As a countermeasure against this problem, a method has been proposed in which the entire nozzle is covered with a silicone heating element, as shown in FIG. 1, or a method in which the tip of the nozzle is particularly thickly covered with a carbon heating element, as shown in FIG. That is, the nozzle 3 supported in a fixed position with respect to the roll 2 rotating by the nozzle support l is surrounded by a siliconite heating element 4 (FIG. 1) or a carbon heating element 5, and these heating elements are directly energized. Alternatively, there is a method in which the temperature is maintained by heating using heat generated by the high frequency coil 6 or the like. With such a configuration, the temperature at the tip of the nozzle can be easily raised to about 13001:1, but in this case, a heat insulating material 7 or an insulating furnace body 8 supporting the heating element is installed. This is not an industrially preferred method. In other words, in order to produce fine wire, the distance from the nozzle tip to the roll surface is generally 0.2.
wm or less, but if such an insulating furnace body is provided, the distance between the nozzle tip and the roll surface will be the same as the thickness of the insulating furnace body (generally about 5W), If this distance is much longer than 0.2 square meters, it becomes difficult to produce fine wires.
一方、ノズルの先端部をガスバーナーで加熱する方法も
試みられているが、このような方法はノズルの開孔部に
炎が直接当る結果、ノズルの内部の溶湯の組成が変動し
、均質な細線を得ることができないという欠点がある。On the other hand, a method has been attempted in which the tip of the nozzle is heated with a gas burner, but as a result of the flame hitting the opening of the nozzle directly, the composition of the molten metal inside the nozzle fluctuates, making it difficult to maintain homogeneity. The disadvantage is that fine lines cannot be obtained.
本発明の目的は上述のような従来の欠点を解消し、作業

。SiC materials or graphite materials can also be used as the conductive material constituting the nozzle, but these materials have sufficient corrosion resistance against molten iron alloys, etc. When manufacturing thin alloy wires, there is a risk that SiC or graphite will ooze out from the inner wall surface of the nozzle into the molten metal, causing problems such as variations in the composition of the molten metal and variations in the size of the nozzle hole. Therefore, when manufacturing fine wire from molten alloy or the like, it is important to consider the corrosion resistance of the nozzle material against the molten metal. The corrosion resistance of the material constituting the nozzle against molten metal is sufficient if the corrosion depth is 5 μm or less when held in molten metal at approximately 1500C for 5 hours, and it is considered suitable for use as a nozzle material. I can say it.
