用いられる。このように、黄銅材表面に伝導層を
形成させることにより、銅材等の良導伝性材料を
そのまま用いるのに比べて原材料コストが低くな

BACKGROUND ART Conventionally, a conductive layer of a good conductor such as copper is formed on the surface of a brass material by plating, thereby reducing the contact resistance of the brass material. The treated brass material is used as a terminal base material and the like. In this way, by forming a conductive layer on the surface of the brass material, the raw material cost is lower than when using a highly conductive material such as copper material as is, and the contact resistance is about the same. Benefits arise. However, the conventional method described above requires a large plating apparatus, resulting in low productivity and high processing costs. Furthermore, the conductive layer formed by plating is easily peeled off, so it is extremely difficult to bend the brass material, which has become a hoop material, into parts after plating. I also had the above problem.
鍍金処理のほかに、金属板表面に異種金属を形
成させる技術として、溶射法や金属シート溶接法
等があるが、このような方法を用いて前記のよう

ストが高く、得られた黄銅材の品質が劣るといつ
たように問題があつた。 In addition to plating, there are thermal spraying methods, metal sheet welding methods, and other techniques for forming dissimilar metals on the surface of a metal plate, but even if you use these methods to make brass materials like the one described above, However, there were problems such as high processing costs and poor quality of the brass material obtained.

料を用いる必要がなく、鍍金処理を行う場合に比
べ製造装置が小さなものですみ、生産性も高い。
そのうえ、加工コストが低く、得られる黄銅材の
伝導層は剥離する恐れがほとんどない。 Therefore, by heating the brass material under reduced pressure to evaporate the zinc on the surface, it is possible to create a brass material 1 having a conductive layer 1a with a high copper content on the surface, as shown in FIG. thought out. If the brass material is manufactured in this way, there is no need to use other metal materials, and compared to the case where a plating process is performed, the manufacturing equipment can be smaller and the productivity is higher.
Moreover, the processing cost is low, and the conductive layer of the resulting brass material has little risk of peeling.

されるている。 The manufacturing method of this brass material will be explained in detail. This method of manufacturing brass material is carried out using, for example, a manufacturing apparatus as shown in FIG. As shown in the figure, this manufacturing device is equipped with an unwinding drum 2 and a winding drum 3, and the unwinding drum 2 is equipped with a brass material 4, which is a raw material used as a hoof material, wound around the winding drum. A brass material 5 that has been subjected to a dezincing treatment is wound around the wire 3. A preheater 6, a vacuum heating furnace 7, and a rolling mill 8 are provided in order between the unwinding drum 2 and the winding drum 3, and the brass material 4 sent from the unwinding drum 2 is passed through these in order. It's starting to pass. The preheater 6 is for removing oil, moisture, etc. adhering to the brass material 4 and drying it. A heating chamber 9 is provided in the center of the vacuum heating furnace 7, and two preliminary vacuum chambers are provided before and after the heating chamber 9, namely, preliminary vacuum chambers 10a and 10b at the front, and preliminary vacuum chambers 10c and 10 at the rear.
d is provided. Preliminary vacuum chambers 10a to 10d
is provided to increase the degree of vacuum in the heating chamber 9 by increasing the degree of vacuum (degree of reduced pressure) in order toward the heating chamber 8. Each of the preliminary vacuum chambers 10a and 10d is provided with an inlet 11 for inert gas such as nitrogen gas. An inert gas such as nitrogen gas is introduced to remove oxygen in the heating chamber 9 to prevent oxidation of the brass material 4. A heating device (heating section) 1 is provided in the heating chamber 9.
2 is placed. Although not shown in the figure, a pressure reducing device such as a vacuum pump is disposed in the vacuum heating furnace 7. Further, a zinc recovery means, such as a metal plate, for recovering zinc by adhering it thereto is arranged in the heating chamber.

により回収する。 Using this device, brass material is produced in the following manner. The raw material brass material 4 mounted on the unwinding drum 2 is sent to a preheating chamber 6 to remove oil and water and dried, and then sent to a heating chamber where it is heated under reduced pressure. For example, the atmospheric pressure inside the heating chamber 7
When the vacuum is about 10 -2 to 10 -4 Torr (higher vacuum than about 10 -2 Torr), the brass material is heated to about 500 to 900°C. Zinc, a low boiling point component, has a temperature of 930 at 1 atm.
It evaporates at a boiling point of 10 -2 to 10 -4 Torr, which is close to a complete vacuum, at a temperature of 500 to 900°C. On the other hand, copper, which is a high boiling point component, has a boiling point of 2582° C. at 1 atmosphere, which is considerably higher than that of zinc, and hardly evaporates at the above pressure and temperature. Utilizing such a difference in boiling point (difference in vapor pressure) between zinc and copper, zinc on the surface of the brass material 4 is selectively evaporated and removed. Then, a conductive layer containing a large amount of copper is formed on the surface of the brass material.
The evaporated zinc is recovered by attaching it to a zinc recovery means.

れる黄銅材５は巻取ドラム３に巻取られる。こう
して第１図に示されているような黄銅材が得られ
る。 After dezincing treatment, the brass material 4 is transferred to a rolling mill 8.
It is then rolled to a predetermined thickness. Immediately after treatment, the brass material 4 has improved electrical properties due to high-temperature heating, but on the other hand, mechanical properties, that is, strength, have decreased due to evaporation of zinc and formation of pores, and the surface has become rough. . However, this rolling improves the strength and makes the surface flat. The brass material 5 obtained by rolling is wound around a winding drum 3. In this way, a brass material as shown in FIG. 1 is obtained.

び蒸発する恐れが多い。そのため、亜鉛の回収率
が低下したり、亜鉛が再び黄銅材に付着する恐れ
が多くなるといつた問題が発生していた。 However, in this method of manufacturing brass materials, zinc is recovered by adhering it to the zinc recovery means installed in the heating chamber, so even if the zinc adheres to the zinc recovery means, the temperature is high enough to generate kinetic energy. For the reasons mentioned above, there is a high risk that the zinc will evaporate again. This has caused problems such as a decrease in the zinc recovery rate and an increased risk of zinc re-adhering to the brass material.
この発明は、このような事情に鑑みなされたも
ので、亜鉛等の低沸点成分の回収率が低下した

This invention was made in view of the above circumstances, and it is possible to reduce the possibility that the recovery rate of low boiling point components such as zinc will decrease or that the low boiling point components will adhere to alloy materials such as brass materials again. The purpose is to provide a collection method for

The inventors have conducted repeated research to solve the above problems. As a result, it is possible to install a cooling chamber equipped with a cooling means connected to the outlet of the heating chamber, heat the brass material in the heating chamber, then pass it through the cooling chamber, and collect the evaporated zinc in the cooling chamber. I found out that. In addition, we have discovered that even when processing alloy materials other than brass materials consisting of components with different boiling points, the same effect can be obtained if low boiling point components are recovered in the same manner, and we have hereby devised this invention. completed.

The gist of this method is to heat an alloy material in a heating chamber, then pass it through a cooling chamber, and collect the evaporated low-boiling components in the cooling chamber. This invention will be explained in detail below.

is provided. In addition, the front and rear of these
An inlet 13b and an outlet 13c for the alloy material 16 which has become a hoop material are also provided. Since the inlet 13b is connected to the outlet 17a of the heating chamber 17, the heating chamber 17
It has a shape (opening size, etc.) that can minimize heat loss due to radiation from the heating chamber 17 and allow floating low-boiling components generated in the heating chamber 17 to pass through. On the other hand, the outlet 13c has a shape that makes it difficult for floating low-boiling components to pass through. Inside the cooling chamber 13, a plate 18 for adsorbing low boiling point components is arranged along the inner wall surface.
is located. This plate for adsorption of low boiling point components 1
8, when the ceiling wall 13a is removed, the cooling chamber 13
It is now possible to take it out. The plate 18 is preferably made of a material that has high thermal conductivity and releases little gas into the vacuum.

After preheating the alloy body 16, etc., the alloy material 16 is heated in the heating chamber 17, and then the alloy material 16 is sent to the cooling chamber 13. The low boiling point component vapor 19a generated in the heating chamber 17 passes through the inlet 13b of the cooling chamber 13 and hits the plate 18, where it is cooled and adheres thereto. The vapor 19a of the low boiling point component generated in the cooling chamber also hits the plate 18 and is cooled and adheres thereto. The low boiling point component 19b recovered in the cooling chamber 13 is taken out together with the plate 18 by removing the ceiling wall 13a. Thereafter, the alloy material 16 is processed in the same manner as before.
For example, after being sent to a vacuum preliminary chamber connected to the outlet 13c of the cooling chamber 13, the rolling treatment is performed.

質が高いものとなる。 In the method for recovering low boiling point components according to the present invention, since the low boiling point components are recovered in a cooling chamber that is independent from the heating chamber and is equipped with a cooling means, there is no risk that the recovered low boiling point components will evaporate again. Very few. Therefore, the recovery rate of low-boiling components is increased. Furthermore, the risk of low boiling point components adhering to the alloy material again is greatly reduced, so the quality of the resulting alloy material is high.

It may be possible to collect this. However, if the cooling chamber is equipped with a plate for adsorbing low-boiling components, it is convenient because by removing this plate, the collected low-boiling components can be quickly taken out from the cooling chamber.

In making this, a cooling chamber equipped with cooling means is connected to the outlet of the heating chamber, and after the alloy material is heated in the heating chamber, it passes through the cooling chamber, and the evaporated low-boiling components are collected in the cooling chamber. Therefore, the recovery rate of low boiling point components is increased. Furthermore, the possibility that low boiling point components will adhere to the alloy material again is greatly reduced, and the quality of the obtained alloy material is high.
