The hot dip method, in which plating is carried out by contacting and adhering a molten low-melting metal to the surface of the filament, is widely used industrially. For example, the hot dip method is used to plate the surface of steel wire or steel strip with Zn or Al, or to plate the surface of copper wire or brass strip with Sn or Sn-Pb. Although this method is an industrial process with a long history and many proven results, there are still many problems that need to be improved.

このような従来の装置には次のような欠点があ
る。 Below, the conventional technology and its problems will be explained using as an example the production of Sn-plated copper wire, which is consumed in large quantities for electrical and electronic industries and is of great interest from both cost and quality perspectives. A conventional device for applying Sn plating to copper wire is shown in Figure 1. That is, a copper wire 3 is introduced from above into a hot dip tank 2 filled with molten Sn 1, the direction of the copper wire 3 is changed by a turn roll 4 installed in the tank, the wire is pulled out of the tank, and a drawing die 5 is used to draw the copper wire 3 out of the tank. Excessive Sn attached
After squeezing it out, it is cooled.
Such conventional devices have the following drawbacks.

In order to achieve the above object, the present invention provides a hot dip tank running in the vertical direction of the wire body and a molten metal storage tank, and allows the molten metal to flow continuously or intermittently between the hot dip tank and the wire of the hot dip tank. A sealing member was installed on the inlet side of the strip, and a drawing die was installed on the outlet side to regulate the plating thickness.In addition, a weir was installed to isolate the inside of the hot dip tank from the outside air and to adjust the level of the hot water level inside the hot dip tank. It is characterized by this.

防止する。 When the filament passes through the hot dip tank from bottom to top, the sealing member is installed at the bottom of the hot dip tank to prevent hot water from leaking, and the drawing die is installed at the top of the hot dip tank above the hot water level or below the hot water level. It is installed so that it is submerged in the water to regulate the plating thickness.
If the filament passes from top to bottom, the sealing member should be placed above the hot water level at the top of the hot dip tank.
Alternatively, it is installed so as to be immersed in the hot water surface to isolate the inside of the tank from the outside air, and the drawing die is installed at the bottom of the hot dip tank to regulate the plating thickness and prevent hot water leakage.

FIG. 2 shows an embodiment of the present invention. A filament 3 such as a copper wire, for example, is introduced into a hot dip bath 8 from the bottom through a cleaning device 6 and a flux coating/preheating device 7. The hot dip tank 8 contains molten metal 1.
The hot water is supplied from the hot water storage tank 9 through the piping 11 by the pump 10 into the hot dip tank 8, and the excess overflows from the weir 12 provided in the tank, passes through the piping 13 and the filter 14, and is fed into the hot water storage tank 9. will be returned to. In other words, the molten metal 1 is refluxing through the above route. The level of the hot water surface 1a in the hot dip tank 8 is determined by the height of the weir 12. Therefore, when the traveling speed of the filament 3 is constant, the immersion time of the filament 3 in the molten metal 1 can be adjusted by changing the height of the weir 12. A heater 15 is installed in the hot water storage tank 9 to keep the molten metal 1 at a predetermined temperature. The pump 10 may be operated continuously or intermittently. The above-mentioned reflux keeps the molten metal 1 in the hot dip tank 8 clean.

線条体とのクリアランスにより調節する。 A die-shaped seal member 16 is installed at the bottom of the hot dip tank 8, and a drawing die 1 is installed at the ceiling.
7 are installed, and the filament body 3 passes through both of these and runs linearly from bottom to top. In this case, the sealing member 16 prevents leakage of the molten metal 1, and the drawing die 17 makes the plating thickness constant and prevents outside air from flowing into the tank. As the sealing member 16 and the drawing die 17, a die made of diamond, cemented carbide, or ceramic and having a hole similar in cross-sectional shape to the cross-sectional shape of the filament 3 can be used. The sealing effect and plating thickness are adjusted by the clearance with the striatum.

It is preferable to keep it in circulation. This is effective in preventing oxidation of the hot water surface 1a and eliminating the harmful effects of gases generated from unavoidable deposits on the surface of the filament. Instead of using inert gas, the hot water surface can be covered with charcoal powder or oil, and the generated CO and H 2 can protect the hot water surface.

と同じである。 FIG. 3 shows another embodiment of the invention. This hot dip device is of a type in which the filament 3 travels from top to bottom, and therefore includes a cleaning device 6, a flux coating/preheating device 7, a sealing member 16, and a drawing die 1.
7 and the cooling device 18 are vertically reversed from the previous embodiment. The other configurations are the same as in the previous embodiment.

動や断線をさらに少なくできる。 The two embodiments described above have the following advantages. That is, since the filamentous body simply passes linearly in the vertical direction within the hot dip bath, no large tension is applied to the filamentous body, and stretching or cutting of the filamentous body can be prevented. In addition, the immersion time of the filament in the molten metal can be easily adjusted by changing the level of the molten metal, making it easy to control the plating thickness and suppressing the generation of dross and intermetallic compounds that lead to quality deterioration. can. Furthermore, since the inside of the hot dip tank is isolated from the outside air, no slag is generated, improving quality and reducing loss of molten metal and energy. Since the molten metal is not oxidized even at the drawing die, variations in plating thickness and wire breaks can be further reduced.

によつて洗われるようになるから、上記の問題点
は解消できる。 FIG. 4 shows yet another embodiment of the present invention. In this device, a drawing die 17 provided at the top of the hot dip tank 8 is supported by the lower end of a cylindrical body 19 extending downward from the ceiling of the tank.
It is immersed in a. Although FIG. 4 shows only the hot dip bath 8, the structure other than the above is the same as the apparatus shown in FIG. In the apparatus shown in FIG. 2, the drawing die 17 is located outside the hot water, and there is a possibility that dross and the like generated little by little may gradually accumulate on the lower surface of the drawing die 17 during long-term operation. With the configuration of this embodiment, the lower surface of the drawing die 17 is always washed with molten metal, so the above-mentioned problem can be solved.

面が常に洗われるからである。 In addition, in FIG. 4, the drawing die 17 is placed so as to be immersed in the hot water surface 1a, but the same effect can be obtained even if it is placed very close to the hot water surface 1a without being immersed in the hot water surface 1a. This is because the lower surface of the drawing die 17 is constantly washed by the viscous flow of the molten metal 1 as the filament 3 travels.

This device is the same as the device shown in FIG. 3, except that the sealing member 16 is supported at the lower end of the cylinder 19 and immersed in the hot water level 1a. In the apparatus shown in FIG. 3, since the sealing member 16 is located outside the hot water, a small amount of outside air inevitably flows in, which significantly increases the consumption of inert gas. If configured as in this embodiment, the molten metal 1 with high specific gravity and surface tension will
Can prevent infiltration of outside air.

効である。(c) Since the molten metal is circulated between the hot dip tank and the hot water storage tank, various products generated in the hot dip tank can be dropped into the hot water storage tank and removed. Therefore, the molten metal in the hot dip tank can always be kept clean, which is also effective in improving quality and reducing wire breaks.
