Embodiment 1

[0062] with attached figure 1 , 2 The copper-aluminum composite panel was prepared by the method shown:

[0063] 1) Billet making: select pure aluminum plate as the cladding plate 1, the plate size is 200mm (length) × 50mm (width) × 2mm (height), and the pure copper plate is used as the base plate 2, and the plate size is 200mm (length) × 50mm (width) × 8mm (height). Use a grinding tool equipped with a wire brush to grind the surfaces to be combined between the pure copper and pure aluminum plates to a "sand surface" effect to remove oxides on the surface of the slab and create favorable conditions for copper-aluminum composite. The heads and tails of the plates are stacked and riveted to ensure that the base-complex plate is smoothly and synchronously bitten, and that it will not deviate during the rolling process, and the composite plate blank 3 is obtained.

[0064] 2) Rolling: The upper roll is corrugated roll 4 and the lower roll is ordinary flat roll for rolling, and ...

Embodiment 2

[0073] with attached figure 1 , 2 The carbon steel-stainless steel clad plate was prepared by the method shown:

[0074] 1) For billet making, select the s316L plate as the cladding plate 1, the plate size is 200mm (length) × 50mm (width) × 2mm (height), the Q345R carbon steel plate is used as the base plate 2, and the plate size is 200mm (length) × 50mm (width) ×8mm (height). Use a grinding tool equipped with a wire brush to grind the joint surfaces of the pure copper plate and pure aluminum plate after stress relief annealing to a "sand surface" effect, so as to remove oxides on the surface of the slab and create favorable conditions for the composite of carbon steel and stainless steel. , and then stack the polished surfaces of the carbon steel and stainless steel plates, weld the carbon steel and stainless steel around, and weld a vacuum tube at the interface of the billet head to be joined, and use a vacuum pump to vacuum the billet to prevent the joint interface.

Abstract

The invention belongs to the technical field of material machining of metal composite boards, particularly relates to a continuous laminating and rolling method for a corrugated interface double-metalcomposite board. The method is characterized in that blanks are rolled into corrugated composite boards by adopting a corrugated roller, the stress peak value is formed at wave troughs of the composite boards, and the combination of the wave troughs is promoted, rolling is carried out by adopting a flat roller, then the stress peak value is formed at the wave crests of the corrugated composite boards so that the relatively high strength combination is realized at the wave peaks, and the high-strength combination of the composite board from the local to the whole surface can be realized by utilizing the two stress peaks at different positions. The extension of metal in the rolling process of the corrugated composite board is mainly achieved through downward pressing of the metal at the position of the wave crests, flowing of the metal at the wave troughs is very small, so that the wave troughs of the corrugated composite boards are not prone to breakage in the flattening process, moreover, the downward pressing of the metal at the wave crest applies a reverse extrusion stress to the wave trough of the composite board at the other side, then the bonding strength at the original wavetrough is further improved, and the double-metal composite board with the good board shape is obtained.

Description

technical field [0001] The invention belongs to the technical field of material processing of metal composite plates, in particular to a method for continuous stacking and rolling of corrugated interface bimetal composite plates. Background technique [0002] In the past century, with the rapid development of science and technology, especially the rise of high-precision technology, the limitations of a single metal have become increasingly prominent, whether in terms of resource consumption, cost, or the use and performance of materials. Many fields cannot meet the needs of modern industrial production and high-tech development. In order to comply with the historical trend and the needs of social development, composite materials have officially entered the stage of history. [0003] Double composite board is a kind of composite material. Because it has the advantages of two metals, it is widely used in aerospace, weapon manufacturing, household appliances and other fields. ...
