Abstract

The invention relates to the technical field of metal clad plate preparation, in particular to a metal clad plate rolling method for forming an interlaced bonding interface, and aims to solve the technical problems that a metal clad plate manufactured by adopting an existing rolling method is low in interface bonding strength, easy to warp, low in yield and the like. According to the technical scheme, corrugated surfaces are prefabricated on a base plate and a compound plate through a corrugated flat rolling machine, the corrugated surfaces of the base plate and the compound plate are oppositely stacked at 90 degrees when a clad plate blank is made, and then flat rolling is conducted. Compared with a traditional rolling method, the method is simple in blank making, cross rolling between the base plate and the compound plate can promote cracking of an oxide layer at a bonding interface and extrusion of fresh and activated metal atoms to the maximum extent, larger-range metallurgical bonding between the two kinds of metal is achieved, and the metal clad plate with high bonding interface strength and good upper and lower surface quality can be prepared.

Description

technical field [0001] The invention relates to the technical field of metal composite plate rolling, in particular to a metal composite plate rolling method for forming an interwoven 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. It can integrate high strength, high toughness, wear resistance, corrosion resistance and other excellent properties of component metal materials. At the same time, metal composite panels can also save precious metal materials and reduce product costs. At present, the manufacturing methods of metal composite panels include explosive composite method, diffusion composite method, hot / cold rolling composite method, etc. Among them, the explosive composite method and the diffusion composite method generally have the disadvantages of low interface bonding rate, uneven...
