Abstract

The invention relates to the technical field of metal composite plate preparation, and particularly relates to a metal composite plate rolling method capable of strengthening the deformation behavior of a bonding interface. The metal composite plate rolling method aims to solve the technical problem that the interface bonding strength of a metal composite plate prepared by adopting an existing rolling method is low. According to the technical scheme, a corrugated roller rolling mill is adopted for rolling a base plate and a composite plate in the first pass, wherein an upper roller adopts a crossed corrugated roller, a lower roller adopts a one-way corrugated roller with one-way corrugations, and the metal composite plate with the upper surface being a crossed corrugated surface, the lower surface being a one-way corrugated surface and the bonding interface being a complex crossed corrugated surface can be obtained; and a flat roller rolling mill is adopted for rolling the upper surface and the lower surface flat in the second pass. Compared with a traditional rolling method, the rolling process of the method is simple, the deformation behavior of the bonding interface of the metal composite plate can be strengthened by using the corrugated roller rolling mill, diffusion of two metal atoms is promoted to a greater extent, firm bonding is formed, warping of the plate can be reduced, and edge cracking can be inhibited.

Description

technical field [0001] The invention relates to the technical field of metal composite plate preparation, in particular to a metal composite plate rolling method that can strengthen the deformation behavior of the bonding interface. Background technique [0002] The metal composite panel is a composite material that is made of two or more layers of heterogeneous metals processed by a special process to achieve interfacial metallurgical bonding. After metallurgical bonding, the plate not only has the characteristics of wear resistance, corrosion resistance, oxidation resistance, and long service life, but also has excellent mechanical properties such as high strength, toughness, impact resistance, and stretchability. It can also save precious metal materials and reduce production costs. . Therefore, it is widely used in aerospace, petrochemical, shipbuilding, electric power, machinery manufacturing and other fields. In view of the perfect combination of low cost and high pe...
