に困難であるという問題もあつた。 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. 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 as is, and the contact resistance is about the same. benefits will arise. However, the conventional method as described above has the problem that the plating apparatus is large and the productivity is low. Furthermore, since the conductive layer formed by plating is easily peeled off, it is extremely difficult to bend the brass material, which has become a hoop material, into parts after plating. It was hot too.
そこで、減圧下、黄銅材を加熱して表面の亜鉛

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 produce a brass material 1 having a conductive layer 1a with a high copper content on the surface, as shown in FIG. thought out. By making brass material in this way, there is no need to use other metal materials. Compared to plating, the manufacturing equipment is smaller and productivity is higher. Moreover, the resulting conductive layer of the brass material has little risk of peeling off.

空ポンプ等の減圧装置が配置されている。 The manufacturing method of this brass material will be specifically explained. This brass material is manufactured 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 winding drum 2. 3 shows brass material 5 that has been subjected to dezincification treatment.
is being wound up. Winding drum 2
A preheater 6, a vacuum heating furnace 7, and a rolling mill 8 are provided in order between the winding drum 3 and the winding drum 3, so that the brass material 4 sent from the winding drum 2 passes through these in order. It's summery. The preheater 6 is used to remove moisture from oil adhering to the brass material 4 and dry 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 (for example, nitrogen gas). Nitrogen gas is introduced to remove oxygen from 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, the vacuum heating furnace 7 is equipped with a pressure reducing device such as a vacuum pump.

れているように、黄銅材４表面の亜鉛１３を選択
的に蒸発させ除去する。そして、黄銅材４表面に
銅成分の多い伝導層４ａを形成させるのである。 Using this device, brass material is produced in the following manner. The raw brass material 4 mounted on the winding 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, if the atmospheric pressure inside the heating chamber 7 is 10 -2 ~
When the vacuum is about 10 -4 Torr (higher vacuum than about 10 -2 Torr), the brass material is heated to about 500 to 900°C. Zinc evaporates at a boiling point of 930°C at 1 atm, but evaporates at a temperature of 500°C to 900°C at a temperature of 10 -2 to 10 -4 Torr, which is close to a complete vacuum. On the other hand, copper has a boiling point of 2582° C. at 1 atmosphere, which is considerably higher than that of zinc, and hardly evaporates at the above-mentioned pressure and temperature. Utilizing such a difference in boiling point (difference in vapor pressure) between zinc and copper, the zinc 13 on the surface of the brass material 4 is selectively evaporated and removed, as shown in FIG. Then, a conductive layer 4a containing a large amount of copper is formed on the surface of the brass material 4.

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, where it is 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.
しかしながら、この黄銅材の製法では、黄銅材

もに、一定した品質の黄銅材を得ることを困難と
なる。 However, this manufacturing method for brass materials evaporates (desorbs and scatters) zinc from the surface of the brass material, so there is a problem in that the evaporated zinc adheres to the furnace wall, which has a lower temperature than the heating section. . It is extremely difficult to remove and recover zinc attached to furnace walls. In addition, as the processing of brass materials increases, zinc accumulates on the furnace walls and contaminates the inside of the equipment, making it difficult to remove and recover the zinc and making it difficult to maintain consistent quality brass materials. It becomes difficult to obtain.

In producing a brass material having a conductive layer with a high copper content on its surface, we developed a zinc recovery method characterized by collecting evaporated zinc by attaching it to a removable collector installed in a heating chamber. This is the summary. This invention will be explained in detail below.

筒形）２５で覆われている。 FIG. 4 shows how a collector is provided in a heating chamber (heating vacuum furnace). As shown in the figure, this heating chamber 14 consists of two box-shaped wall members 15a and 15b.
It consists of a structure that combines the Wall members 15a, 15b
are connected to each other by bolts and nuts 16, and can be separated as necessary. The reason for making it separable is to enable the collector to be taken out, but it may also be possible to take out the collector by other means, such as by providing a door on the wall. A heating device (heating unit) 17a and a metal plate 18a serving as a collector are arranged in the upper part of the interior of the heating chamber 14 so as to face each other in a "V" shape, and the metal plate 18a serving as a collector is arranged in the lower part so as to face each other in an inverted "V" shape. Heating device 17
b and a metal plate 18b are arranged. Here, the heating devices 17a and 17b are designed to generate radiant heat 19. Metal plates 18a, 18b
Cooling units 20, 20 are provided on the back surfaces of the metal plates 18a, 18b, respectively, so that the metal plates 18a, 18b are cooled by water cooling or the like from the back surfaces. Cooling section 20
A wall material 22 for creating a space 21 on the back side of the metal plates 18a and 18b, and two pipes 23 and 24 connected to the wall material 22 and serving as an inlet and an inlet for the space 21 and a refrigerant such as water or N2 . It consists of The metal plates 18a and 18b can be freely removed from the cooling section. The inner wall circumferential surface of the heating chamber 14 is covered with a metal plate (wholly cylindrical) 25 that serves as a collector.

のが非常に容易である。 In this way, when the cooling metal plates 18a, 18b and the uncooled metal plate 25 are arranged and zinc is evaporated from the surface of the brass material 4, the zinc adheres to these. That is, since the metal plates 18a and 18b are cooled from the back side, when the zinc vapor hits the front surface, it cools and adheres to the metal plates 18a and 18b. In the figure, 26 represents attached zinc.
Further, the metal plate (tube) 25 is heated by the heating devices 17a and 17.
Since the temperature is lower than in the vicinity of b, when the deleading vapor hits the surface, it cools and adheres to the surface. The metal plates 18a, 18b and the metal tube 25 are connected to the wall member 15.
If a and 15b are separated, they can be taken out and replaced with new metal plates or metal tubes. Therefore, it is very easy to remove and recover zinc from the heating chamber 14.

着した亜鉛をあらわす。 In the above, a double-sided heating type heating chamber that heats both sides of the brass material at the same time has been described.Next, a single-sided heating type heating chamber that heats one side at a time will be described. Compared to the double-sided heating type, the single-sided heating type makes it easier to make the vacuum heating furnace more compact. It is easier to control the thickness of the dezincing layer (conductive layer) of the brass material. It is said that by increasing the number of heating devices (number of stages), it is easy to perform dezincification in parts and stages, which is convenient when it is necessary to dezincify only on the ground. There are advantages. In the case of a single-sided heating type, for example, as shown in Figure 5,
Two heating chambers (heating vacuum furnace) 27 (stage 1) and 28 (stage 2) are arranged one above the other, and after the brass material 4 passes through the heating chamber 27, it makes a U-turn and passes through the heating chamber 28. . Then, dezincing treatment is performed on each side in the two heating chambers 27 and 28. The insides of the heating chambers 27 and 28 have the same structure, and a metal plate serving as a collector and a heating device 30 are arranged to face each other vertically. Further, a metal cylinder 31 is arranged to cover the inner periphery of the wall that serves as a collector. Although not shown in the figure, the walls of the heating chambers 27, 28 can be separated into two parts, or a door is provided on the wall, so that the inside of the heating chambers 27, 28 can be accessed. The arranged metal plate 29 and metal cylinder 31 can be easily taken out and replaced. Therefore, zinc is also very easy to remove and recover. In the figure, 26 represents zinc attached to the metal plate.

うにするのがよい。 In the above examples, two types of collectors are provided in the heating chamber, but only one type or three or more types of collectors may be provided in some cases. Further, the number of collectors to be installed can be determined as appropriate. The collector is not limited to being made of metal, but may also be made of other materials. The collector should be installed as far away from the heating device as possible. Placement of the collector in a location where it is exposed to zinc vapor or covering the furnace wall with the collector may be implemented as appropriate.If a cooling section is connected to the collector, the cooling section should also be kept as far away from the heating device as possible. It is better to keep them apart.

Therefore, maintenance of the heating chamber,
Inspection becomes easier, the operating rate of manufacturing equipment increases, and the productivity of brass materials increases. Furthermore, if the collector is replaced before zinc accumulates in the heating chamber, it becomes easier to obtain a brass material of consistent quality. Furthermore, the pure zinc deposited on the collector can be easily reused industrially.
