上の問題もあった。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 profiteer, etc. In this way, by forming a conductive layer on the surface of the brass material, there are advantages such as lower raw material costs and a similar contact resistance compared to using a good conducting material such as steel as is. . However, the conventional method described above requires a large plating apparatus, resulting in low productivity and high processing costs. Moreover,
The conductive layer formed by plating is easy to peel off, so
After plating the brass material that has become a hoop material, etc.
There was also a quality problem in that it was difficult to bend and make parts due to the weight of the eggs.

性も高い。Therefore, we thought of creating a brass material with a conductive layer containing a large amount of copper on its surface, as shown in Figure 1, by heating the brass material under reduced pressure to evaporate the zinc on the surface. Served. 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.
そのうえ、加工コストが低く、得られる黄銅材の伝導層

鉛回収手段が配置されるでいる。The manufacturing method of this brass material will be specifically explained. 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. A brass material 4, which is a raw material used as a hoop material, is wound and mounted on the unwinding drum 2. A brass material 5 that has been subjected to a dezincing treatment is wound onto the wire 3. A preheater 6. is provided between the unwinding drum 2 and the winding tube 13. A vacuum heating furnace 7 and a rolling mill 8 are provided in this order, and the brass material 4 sent from the unwinding drum 2 passes through these in order. The preheater 6 is for removing oil, moisture, etc. adhering to the brass material 4 and drying it. Vacuum heating furnace 7
A heating chamber 9 is provided in the middle, and two preliminary vacuum chambers are provided before and after the heating chamber 9, that is, preliminary vacuum chambers 10a and 10b are provided at the front, and preliminary vacuum chambers 10C and 10d are provided at the rear. There is. The preliminary vacuum chambers 108 to 10d are heating chambers 8
This 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 9. Each of the preliminary vacuum chambers 10a and 10d is provided with an inlet 11 for inert gas such as nitrogen scum. 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) 12 is arranged within the heating chamber 9 . 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 collecting zinc by depositing it thereon is arranged in the heating chamber.
この装置を使用し、つぎのようにして黄銅材をつくる。Using this equipment, brass material is produced in the following manner.

銅材表面に銅成分の多い伝導層を形成させるのである。The raw material brass material 4 mounted on the unwinding drum 2 is transferred to the preheating chamber 6.
It is then sent to a heating chamber where it is heated under reduced pressure to remove oil and moisture and to be dried. For example, when the pressure inside the heating chamber 7 is set to about 10' to 10-' Torr (higher vacuum than about 10-2 Torr),
Heat the brass material to about 500-900°C. Zinc, which is a low boiling point component, evaporates at a boiling point of 930° C. at 1 atm, but evaporates at about 500° C. to 900° C. at about 10 −2 to 1 O −4 Torr, which is close to a complete vacuum. 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.

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, the brass material 4 is sent to a rolling mill 8,
Here, it is rolled to a predetermined thickness. Immediately after the 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.

亜鉛の回収率が低下したり、亜鉛が再び黄銅材に付着す
る想れが多くなるといっ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. There is a high risk that the zinc will evaporate again due to reasons such as a large amount of heat. Therefore,
Problems such as a decrease in the zinc recovery rate and an increased possibility that zinc would adhere to the brass material again were occurring.

とえば、ステンレススチール等がある。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. −−−−−−−−− Therefore, this invention heats an alloy material consisting of components with different boiling points in a heating chamber, evaporates the low boiling point components on the surface, and forms a layer with many high boiling point components on the surface. In order to produce the alloy material, a cooling chamber equipped with a 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 cooled in the cooling chamber The gist of this invention is a method for recovering low-boiling components. below,
FIGS. 3 and 4, which explain the present invention in detail, show the cooling chamber used in the low boiling point component recovery method according to the present invention. As shown in the figure, this cooling chamber 13 has double walls at the side and lower portions, and a passage 14 for a refrigerant such as cooling water is formed between the walls. Refrigerant inlet/outlet ports 14a, 14b are provided at the lower part and side portions of the cooling chamber 13. The ceiling wall 13a of the cooling room 13 is designed to allow for sushi to be prepared. At the front and rear of the cooling chamber 13, flanges 15a and 15b for removal to other devices are provided. In addition, an entrance 13b of the alloy material 16, which is a hoop material, is provided at the front and rear portions.
and an exit 13c are also provided. Since the inlet 13b is connected to the outlet 17a of the heating chamber 17, heat loss due to radiation from the heating chamber 17 can be minimized, and
It has a shape (opening size, etc.) that allows floating low boiling point 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. This plate for adsorption of low boiling point components 1
8 can be taken out from the cooling chamber 13 by removing the ceiling wall 13a. The plate 18 is preferably made of a material that has high thermal conductivity and releases little gas into the vacuum. Such materials include, for example, stainless steel.

のである。First, the pressure in the cooling chamber 13 as well as the heating chamber 17 is reduced. Then, a refrigerant is passed through the passage 14 of the cooling chamber 13 to cool the plate 18. After preheating the alloy material 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, hits the plate 18, 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, the cooling chamber 130 outlet 13c
After being sent to a vacuum preliminary chamber connected to a vacuum chamber, the rolling process is carried out.
この発明にかかる低沸点成分回収方法では、加熱室から

金材の品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 of the heating chamber and is equipped with a cooling means, there is a risk that the recovered low boiling point components will evaporate again. is low in egg weight. 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.
なお、前記実施例では冷却室が低沸点成分吸着用板体を

却室から取り出すことができ、便利である。In the above embodiment, the cooling chamber is equipped with a plate for adsorbing low boiling point components, but it does not necessarily have to be like this, and the low boiling point components may be attached to the inner wall surface of the cooling chamber. 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.

ものとなる。In the low boiling point component recovery method according to the present invention, an alloy material consisting of components with different boiling points is heated in a heating chamber, and the low boiling point components on the surface are evaporated, so that the alloy material has a layer containing many high boiling point components on the surface. In making this, a cooling chamber equipped with a 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 recovered 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 increased.
