本発明は、爆発圧着法による多層クラッド板の製造方法
、特に部分的に異種金属中間層を有する多層クラッド板
の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a multilayer clad plate by explosive crimping, and in particular to a method for manufacturing a multilayer clad plate partially having a dissimilar metal intermediate layer.

る。Since clad plates manufactured by the explosive crimping method have come to be used in large quantities in various industrial fields, clad plates with special shapes and material combinations are now required. Manufacturing methods have been developed.

合されないという欠点が確認された。For example, when manufacturing a multilayer clad plate partially having a dissimilar metal intermediate layer as shown in FIG. 1, a conventionally known method is to form a recess into which the composite material 2 is inserted in the base material 1 shown in the figure. The composite material 2 is put into the recess, and the detonation is started from point P in the same figure so that the unattached part is at most 4. The method is to explosively press both sides at the same time, or the base material 1 is laminated as shown in FIG. ,lb,lc
The base material 2 is explosively crimped to the base material la, then the base material lb is explosively crimped to the non-crimped part of the composite material side of this clad plate, and then the matrix of this cladding slope is Material lb, composite material 2
There is a multiple explosion crimping method in which the mother village LC is explosive crimped on the surface. However, when explosive crimping is carried out using these methods, in the former case, the area around point P in Fig. 1 becomes non-crimped over approximately 100 to 20 degrees, and the total plate thickness after explosive crimping is equal to that of the base plate. There is a difference in plate thickness between the chiseled part and the part where the composite material is clad (the clad part is thinner in order to create a gap between the base material and the composite material during crimping work). Become)
In addition, in the latter case, P in FIG.
It was confirmed that there was no pressure bonding in the vicinity of the point for approximately 100 to 20 meters, and that the abutting portion P between the base material lb and composite material 2 in the same figure was not metal-bonded.

、縦；３０仇岬、横；１００仇吻の板を形成した。In Fig. 3A, 1 is a steel plate, la, lb, and lc are three parts of the steel plate 1, 2 is a stainless steel plate, 3 is a butt part,
3a shows a high nickel/copper alloy weld, and 3b shows a low nickel/steel alloy weld. The manufacturing method of this clad plate is a copper plate l
b and the stainless steel plate 2 are butt-welded at the butt portion 3 via a copper-nickel alloy to produce a single plate made of the steel plate and the stainless steel plate, and then this single plate is bonded to the copper plate l.
A is explosively crimped to form a two-layer clad plate by a conventional method, and then a steel plate lc is explosively crimped to the copper plate lb of the two-layer clad plate and the stainless steel plate 2 by a conventional method to produce a three-layer clad plate. In this case, many known butt welding methods such as resistance welding, arc welding, electron beam welding, plasma welding, etc. can be employed as the welding method for the abutting portion 3. Copper-nickel alloys used for butt welding include stainless steel and high nickel alloys with good weldability (for example, 40% Ni, balance of Cu).
However, the stainless steel 2 side may be butt welded with a high nickel alloy 3a (for example, CNP3) that has a high Ni content.
, a low nickel copper alloy (e.g. CNP,
) may be used in a two-layer structure. FIG. 38 shows another embodiment of the present invention, in which the stainless steel plate 2 is positioned in the middle of the copper plate Ib and the steel plate Ib is butted against each other.
A case where a three-layer clad plate is manufactured by explosive crimping of a and lc is shown. Example In manufacturing a three-layer clad plate as shown in Fig. 3A, a pure copper plate (thickness: 5 ribs, length: 30 broadsides,
SuS304 as the stainless steel plate 2
(thickness: 5 side, length: 30 mm, crosspiece: 50 mm), the stainless steel plate 2 side was made of CNP3, and the steel plate lb side was made of CNP. They were butt welded together using a 5-thickness plate, with a length of 30 ribs and a width of 100 ribs.

つクラッド板である。Next, this plate was explosively bonded to one side of a steel plate la (material: pure copper, thickness: 10 skin, length: 300 side, width: 1000 skin) to obtain a two-layer clad plate. After that, a steel plate lc (material:
Pure brocade, Thickness: 1mm, Length: 30mm, Width: 100mm)
were explosively crimped to obtain a three-layer clad plate with a total thickness of 25 ribs. As a result of inspecting this three-layer clad plate by an ultrasonic deep scratch test, it was found that each layer was crimped on the entire surface. The thus obtained three-layer clad plate manufactured by the method of the present invention, in which a stainless steel plate is sandwiched between the parts, is a useful clad plate that eliminates the various drawbacks of the same type of clad plate produced by the secondary method. It is.
