Problems solved by technology

[0002] In the composite production method of aluminum and stainless steel, due to the large differences in hardness, melting point, and specific gravity of the two materials, the composite is very difficult. At present, only a few countries and enterprises abroad can master this kind of production technology (such as the United States and Japan and other developed countries), in China, only a few large enterprises such as Dalian Shipyard can produce thick composite panels with a thickness of more than 15mm, and it can only be completed by explosive composite methods. At the same time, the thickness of aluminum panels must meet 10mm or more, otherwise the compounding is difficult to complete, and because the process of explosive compounding is very complicated and the control coefficient is too high, it is difficult to achieve 100% metallurgical compounding rate at the interface, the output is low, the work intensity is high, and the process is complicated
As a result, the technical indicators in practical applications cannot meet the requirements of customers and cannot meet the needs of actual production.

Embodiment 1

[0042] The finished hot-rolled stainless steel-aluminum-stainless steel clad plate with a thickness of 1.5mm.

[0043] Among them: 304 stainless steel plates with a thickness of 0.3mm for both plates A and C, and 1050 pure aluminum plates with a thickness of 1.5mm for plate B. Soak in dilute hydrochloric acid solution with a concentration of 10% for 10 minutes to clean the remaining oxide layer on the surface of boards A and C. At the same time, soak board B in NaoH solution with a mass concentration of 15% for 10 minutes to clean the residual oxide layer on the surface of the board, and then use high-pressure water Rinse the three boards A, B, and C; secondly, dry the three boards A, B, and C at a temperature of 100-200°C for 5-10 minutes; thirdly, align the three boards A, B, and C Carry out four-corner riveting and fixing; then put the riveted three plates in an annealing furnace that has been heated to 300-650°C, and heat for 10-30min, then take it out, and put it in quick...

Embodiment 2

[0045] Finished hot-rolled stainless steel-aluminum-stainless steel clad plate with a thickness of 3.2mm:

[0046] Among them: 201 stainless steel plates with a thickness of 1.0mm for plates A and C, and 1050 pure aluminum plates with a thickness of 2.0mm for plate B. Its actual operation method is the same as that of Example 1, except that the heating time is correspondingly increased by 5-10 minutes on the original basis. When When the reduction rate reaches 20%, the plate thickness of the composite product can reach 3.2mm;

Embodiment 3

[0048] Finished hot-rolled stainless steel-aluminum-stainless steel clad plate with a thickness of 5.0mm:

[0049] Among them: 316L stainless steel plates with a thickness of 1.2mm for A and C plates, and 1050 pure aluminum plates with a thickness of 3.8mm for B plate. When the reduction rate reaches 20%, the thickness of the composite finished sheet can reach 5.0mm.

Abstract

The invention discloses a hot-rolled stainless-steel-aluminium-stainless-steel composite board production method and application. The composite board consists of three parts A, B and C, the A and the C are stainless steel plates and the B is a pure aluminium plate, wherein the stainless steel plates A and C are 201, 202, 303, 304 and 316L stainless steel plates and have the specifications of length*width*thickness of 2,440mm*1,220mm*(0.3 to 2.5mm); and the pure aluminium plate B is a civil 1050-series pure aluminium plate and has the specification of length*width*thickness of 2,440mm*1,220mm*(1.0 to 50mm). Compared with the prior art, the hot-rolled stainless-steel-aluminium-stainless-steel composite board production method has the advantages that the composite board with the thickness of 1.5mm to 50mm can be produced; the interface recombination rate reaches 100 percent; the working intensity is low; the yield is high; energy is saved; and no pollution or noise is generated.
