特に耐食性の導電棒材の製造に応用して好適な方法であ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for manufacturing a flat laminated material in which a covering material made of a material different from that of the base material is joined around the base material.
This method is particularly suitable for application to the production of corrosion-resistant conductive rods.

い。Electrodes used in industrial plating, salt electrolysis, etc. are required to have not only electrical conductivity but also excellent corrosion resistance with little corrosion due to electrolyte even after long-term use. Finally, a conductive rod material with a flat cross section is used, in which a conductive material such as copper is coated with a corrosion-resistant material such as titanium or stainless steel, and one end of the conductive material is closed with a corrosion-resistant material. In this conductive bar, since electricity is applied to the inner conductive material, it is desirable that the resistance to the surface of the covering material be small, and it is desirable not only to simply bring the two metals into contact, but also to perform diffusion bonding.
そこで、従来、導電棒材を製造する方法として真空拡散
溶接法と熱間圧延拡散溶接法とが採用されている。Therefore, conventionally, vacuum diffusion welding and hot rolling diffusion welding have been adopted as methods for manufacturing conductive bars.

。The former manufacturing method using the vacuum diffusion welding method involves fitting a stainless steel pipe 2 with a larger diameter into a round bar-shaped copper base material 1, and then facing each other. The material is pressed between a pair of press metals 113゜4 to deform it into a flat KlI shape, and the resulting nine-jointed material is placed in the sealed chamber 5 of the vacuum diffusion welding device.
The steel base material 1, the stainless steel pipe 2, and the t- Join. Thereafter, a conductive bar was produced by welding an end plate 9 to one end to prevent infiltration of electrolyte and the like.
この方法によれば極めて高品質１に＃！品が得られるが
、電価で大規模な真空拡散溶接設備が必要となるという
欠点がある。This method achieves extremely high quality #1! However, the disadvantage is that large-scale vacuum diffusion welding equipment is required due to the electric cost.

れて込る。On the other hand, in the latter island pressure fly diffusion #* method, as shown in Fig. 2, the process m' is shown by fitting a stainless steel pipe 2 with a larger diameter into a round bar-shaped copper base material 1. The material is heated in a heating f10 while preventing oxidation, and then brought to an appropriate temperature and woven using a Natsu9 and Zeta roller, and then sent between a pair of opposing rolls 11° and 12 having flat cross-section calibers to be plastically deformed by rolling. - Join the steel base material l and the stainless steel pipe 2. Thereafter, the end plate 9 is welded to form a conductive bar in the same manner as in the case described above.

歩留りも悪化する。In this method, oxidation cannot be prevented during forming because the material is removed from the heating furnace 10 and hot rolled, and air enters the unrolled portion from the open end, causing oxidation and resulting in non-bonded portions. In particular, if the time from removal from the heating furnace IO to rolling is long, the proportion of non-bonded portions will increase (4) and the yield will deteriorate.

とを特徴とする。It is an object of the present invention to provide a method for producing a kettle material that eliminates the above-mentioned conventional drawbacks, does not require large-scale equipment, and can produce high-quality products. The structure of the present invention to achieve such an object is to fit a cladding tube material having a diameter larger than that of the base material into a base material, and to compress and deform the cladding tube material into a flattened material so that the outer circumferential surface of the base material and the cladding tube material are The base material and the cladding tube material are bonded to each other in close contact with each other, after which both ends are sealed to prevent air from entering, and diffusion welding is performed to join the base material and the cladding material.

端開放合わせ材などの耐食性導電棒が得られる。Fig. 3 is a process diagram for example K when press forming is used. First, a stainless steel pipe 21t of a larger diameter than this is coated on a steel base material 20 in the shape of a round bar as a covering pipe material. A pair of press metals 1122.23 facing each other are used to clamp and plastically deform the steel base metal 20 into a flat shape. do. Next, air is applied to both ends of the laminated material 24, which is thus written without any gaps and formed into a flat shape.
The end plates 25 are each welded and sealed to prevent inflow. Thereafter, the steel base material 20 and the stainless steel pipe 21 are placed in a heating furnace 26 for bonding, and heated with a required weight 27 placed thereon to apply surface pressure necessary for bonding, thereby diffusion welding the steel base material 20 and the stainless steel pipe 21. Conventionally, in this diffusion 11II bonding, it was necessary to use a vacuum atmosphere or a non-oxidizing atmosphere to prevent oxidation of the bonding surface, but the copper base material 20 and the stainless steel copper tube 21 were bonded without any gaps. Since both ends are sealed and welded, air is prevented from entering the joint surface, and oxidation does not proceed, allowing diffusion #I contact in the atmosphere. In this way, once the conductive bar material 28 is obtained as a laminate material that has been completely diffusion welded, it can be cut as necessary to produce a one-side sealed material, a two-piece material, a laminate material with both ends open, etc. A corrosion-resistant conductive rod is obtained.

A flat Kll is sent between a pair of opposing rolls 29.
While deforming the steel base material 2o and the stainless steel pipe 21
Make sure they are in close contact with each other without any gaps. In this way, the plugs 31 are inserted into both ends of the nine-joint material 24, which is tightly fitted without any gaps and formed into a flat shape, to prevent air from flowing in, and are sealed by welding.

9. Diffusion welding is performed by sending and rolling for 30 minutes. In this case, in the first nine roll rolling to bring the copper base material 2o and the stainless steel pipe 21 into close contact with each other without any gaps,
The remainder of the flattening of the 2nd im roll is left as follows. In this way, the copper base material 2o and the stainless steel pipe 21 are brought into close contact with each other without a gap, and both ends are seal-welded, which prevents air from entering the joint surface and prevents oxidation from proceeding. In this way, diffusion welding can be carried out in the atmosphere.Once the conductive bar material 28 has been completely diffusion welded and serves as a good joining material, it can be cut as necessary as in the case described above.

丸棒に限らず中空棒等を使用できる。In each of the above embodiments, the end plates or plugs are welded after being brought into close contact with each other without any gaps, but any method may be used, and even when roll forming, the required pressure is applied in a heating furnace. Alternatively, in the case of press forming, diffusion welding may be performed by heating in a heating furnace and then performing diffusion welding by roll forming. Further, the base material is not limited to a round bar, but a hollow bar or the like can be used.

れた合わせ材を製造することができる。As explained above in detail with the embodiments, according to the method of the present invention, when the base material and the cladding material are plastically deformed into flat shapes, the art material is brought into close contact with the joint surface, minimizing air remaining on the joint surface, and both Since it is sealed, air is prevented from entering during the bonding process, and oxidation of the bonding surface does not progress, so good diffusion bonding is possible even in the atmosphere. In addition, since this type of laminated material is often used with one end sealed, sealing both ends before joining requires only a complete change in the order of the steps and does not increase the number of steps. Therefore, diffusion welding can be easily performed using a general heating furnace without requiring expensive equipment, and a bonded material with a high yield and excellent quality can be manufactured.
