Embodiment 1

[0050] Such as figure 1 Shown is a method for preparing a zirconium / steel metal composite board. The prepared zirconium / steel metal composite board is a double-layer metal composite board, and the double-layer metal composite board is composed of a base steel plate 2 and a cladding zirconium board 1. Composite components are formed, and the preparation method of the double-layer metal composite board includes the following steps:

[0051] Step 1. Surface polishing treatment: respectively perform surface polishing treatment on the surface to be compounded of each component forming the double-layer metal composite plate, and make the surface roughness Ra of the clad zirconium plate 1 and the base steel plate 2 to be compounded be ≤12.8 μm; and after surface polishing treatment, the thickness of the cladding zirconium plate 1 is 1-12 mm, and the thickness of the base steel plate 2 is 6-220 mm. During the actual preparation process, the plate thicknesses of the clad zirconium pla...

Embodiment 2

[0066] In this example, the difference from Example 1 is that the prepared zirconium / steel metal composite panel is a three-layer metal composite panel, and the three-layer metal composite panel is composed of the base steel plate 2, the cladding zirconium plate 1 and the The intermediate layer splint 3 between the base steel plate 2 and the cladding zirconium plate 1 is composed of three components. The intermediate plywood 3 is an intermediate copper plate or an intermediate titanium plate, and the material of the intermediate copper plate is GB5231 T1 or GB5231 T2; the intermediate titanium plate is a pure titanium plate, and the material of the pure titanium plate is GB / T3621, TA1 Or TA2 or ASTMB265 Gr.1 or Gr2.

[0067] In this embodiment, the cladding zirconium plate 1 is a 10 mm thick Zr01 plate, the middle plywood 3 is a 3 mm thick T2 plate, and the base steel plate 2 is a 80 mm thick 16MnR steel plate.

[0068] When preparing the three-layer metal composite board, th...

Embodiment 3

[0088] In this embodiment, the difference from Embodiment 2 is that: when performing combined assembly and explosive compounding in step 2, the three components of the three-layer metal composite plate are combined and assembled and explosively compounded using the one-time assembly and compounding method, and Its processing is as follows:

[0089] 211. Lay the base steel plate 2 horizontally on the foundation 8 or on the horizontal operating table.

[0090] 212. Through a plurality of hard metal supports 4 arranged on the upper and lower planes, the middle plywood 3 is horizontally and fixedly installed directly above the base steel plate 2 and the cladding zirconium plate 1 is horizontally and fixedly installed on the front of the middle plywood 3 above, and the distance between the middle plywood 3 and the base steel plate 2 is 2-14mm, and the distance between the middle plywood 3 and the base steel plate 2 is 6-24mm.

[0091] 213. On the top of the clad zirconium plate 1,...
