Description of the Related Art Conventionally, the cooling of a metal wire after being lifted from a plating bath is generally performed by cooling it with water after cooling it to the atmosphere. However, Japanese Utility Model Publication No. 57-13880 discloses a liquid in a tank. Is rotated to perform primary cooling, and a secondary cooling is performed by blowing compressed air from a nozzle in a direction perpendicular to the steel wire at an upper part in the tank. In addition, Tokuhei 4.11838
No. 44 discloses a method of cooling a gas or mist to a steel wire at an angle of 10 to 40 ° and a blowing pressure of 1 to 4 kg / cm 2. Japanese Patent Application Laid-Open No. 6-81107 discloses a method of circulating and supplying a cooling liquid to a cooling container and passing a wire through the cooling container to cool the cooling container.

厚めっき金属線では、従来の一般的な大気放冷後水冷却
をする方法は、大気放冷のみでめっき表層が凝固するに

冷却装置の配置が困難である。In the case of a thick-plated metal wire coated with a hot-dip zinc / aluminum alloy and having a coating weight of 300 g / m2 or more, a conventional general method of cooling the water after cooling it to the atmosphere is as follows. Since it takes a long time for the plating surface layer to solidify only by air cooling, a long distance is required until water cooling, and it is difficult to arrange a water cooling device.

Forcible cooling methods such as those described in JP-A-7-138880, JP-B-4 / 183844 and JP-A-6-81107 are adopted. In the case of thick plating with a coating weight of 300 g / m2 or more, the plating is lifted from the plating bath. If water cooling or water droplet cooling is performed later before the plating surface layer is not solidified, the force of water acts on the plating surface layer, and an uneven pattern is easily generated, which makes it very difficult to adjust cooling conditions.

き表層が凹凸模様が発生し易い。[0005] Also, when cooling by spraying with compressed air or the like, when cooling from a one- or two-way nozzle, the plating at the start of solidification is moved in a direction other than the nozzle direction, causing uneven thickness, and the angle of spraying is reduced by metal. When it becomes larger with respect to the line axis of the wire, the plating surface layer is likely to have an uneven pattern.

It is intended to provide a cooling device for a hot-dip zinc / aluminum alloy-plated metal wire with less uneven thickness.

む方向と同じ方向に噴き出させる。In order to achieve the above object, in the cooling apparatus of the present invention, compressed air is applied in parallel to the axis of a metal wire pulled up from a plating bath and from a cylindrical nozzle. The gas is spouted all around the metal wire and in the same direction as the metal wire travels.

, The metal wire is pulled up in the vertical direction by the sink roll 4, the molten zinc / aluminum alloy is plated by the drawing device 5, and the metal wire 6 plated with the molten zinc / aluminum alloy is cooled by the cooling method of the present invention. After passing through the device 7, it is cooled by the water cooling 13.

う隙間を設ける。In the cooling device 7 of the present invention, a nozzle 12 for jetting compressed air into the outer cylinder 8 is arranged on the same axis as the outer cylinder 8, and the outside air is sucked between the outer cylinder 8 and the nozzle 12. A gap is provided so that

せる。After the compressed air supplied from the compressed air supply pipe 10 is stored in the compressed air reservoir 11 to the nozzle 12, the compressed air is jetted in parallel with the axis of the metal wire 6 and in the same direction in which the metal wire 6 advances. The nozzle 12 is jetted from the cylindrical slit so as to be jetted to the entire circumference of the metal wire 6 from the well-provided nozzle 12.

ットから噴流させるのと同様の機能が得られる。In addition, a plurality of small holes are arranged on the circumference instead of the cylindrical slit, and the small holes are jetted in parallel to the axis of the metal wire 6 and in the same direction in which the metal wire 6 travels, so that the jet flows from the cylindrical slit. A function similar to the above is obtained.
【００１４】この圧縮空気の噴流により冷却装置７の上

冷却能力をあげ、冷却装置７の配置を可能にする。If the supply of compressed air is at normal temperature and the outer cylinder 8 becomes long and the cooling device 7 cannot be arranged, the compressed air to be supplied is previously arranged with a compressed air cooling device, and low-temperature compressed air is supplied. The cooling capacity is increased by supplying the low temperature gas, and the cooling device 7 can be arranged.

て冷却能力をあげることができる。The ambient air sucked from the upper inflow side of the cooling device 7 is close to the molten zinc / aluminum alloy bath 3 and tends to be higher than room temperature. The outside air can be drawn into the upper inflow side of the cooling device 7 or another low-temperature gas can be drawn and sucked to increase the cooling capacity.

Adjust the slit gap and so on.

び偏肉の発生を防げれる効果がある。Compressed air is blown out of the nozzle in parallel with the axis of the metal wire, all around the metal wire, and in the same direction as the metal wire travels. From the gap between the cylinder and the nozzle, the surrounding air is sucked in parallel to the axis of the metal wire, along the entire circumference of the metal wire, and in the same direction as the metal wire travels. The entire circumference can be solidified continuously and uniformly. This has the effect of preventing the occurrence of unevenness and uneven thickness on the plating surface layer.
