Embodiment 1

[0027] refer to Figure 1-6 , a method for rolling a Mg / Al composite plate with double cross corrugated rolls, comprising the following steps:

[0028] S1. Blank making: Select 5052 aluminum alloy plate with relatively small deformation resistance as the base plate 1, the length, width and height are 100 mm, 50 mm, and 2 mm respectively, and select the AZ31 brand magnesium alloy plate with relatively large deformation resistance as the double plate 2. The width and height are 100mm, 50mm, and 2mm respectively. Use a wire brush to polish the surface of the base plate and the double plate to be bonded to remove the surface oxide layer and pollutants. Stack the two plates on the surface to be compounded and fix them at the edges. The metal composite board slab is obtained; here the substrate 1 and the cladding board 2 can be fixed by common methods such as riveting.

[0029] S2, one-pass rolling: the metal composite plate slab 3 prepared in step S1 is first put into the heating ...

Abstract

The invention relates to the technical field of metal clad plate preparation, in particular to a method for rolling a metal clad plate through double crossed corrugated rollers, 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, serious in warping and edge crack and the like. According to the technical scheme, a metal clad plate blank prepared through a conventional method is put into a corrugation rolling mill to be rolled, upper and lower rollers of the corrugation rolling mill are crossed corrugated rollers, the selection range of the reduction rate is 30%-50%, a metal clad plate I with the upper and lower surfaces and the bonding interface being corrugated rollers is obtained, then a flat rolling mill is used for conducting two-pass rolling, the selection range of the reduction rate is 20%-40%, and a metal clad plate II with the upper and lower surfaces being planes and the bonding interface being corrugated surface is obtained. The high-quality metal clad plate which is high in bonding strength, small in residual stress, light in bow warping and few in edge crack phenomenon can be obtained.

Description

technical field [0001] The invention relates to the technical field of metal composite plate preparation, in particular to a method for rolling a metal composite plate with double cross corrugated rolls. 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. Some metal resources have the advantages of excellent corrosion resistance, oxidation resistance, high strength, wear resistance and good biocompatibility, but the high price and limited resources limit the wide application of these materials. In order to solve this contradiction, people have developed a metal composite panel process. The metal composite board combines metals with different properties, integrates the advantages of different metals, and avoids their respective shortcomings, so that the composite board has excellent comprehensive performance that ...
