Method for preparing metal composite plate through double corrugated roll cross rolling

Abstract

The invention relates to the technical field of metal composite plate rolling, particularly to a method for preparing a metal composite plate through double corrugated roll cross rolling, and aims atsolving the technical problems that warping, cracking and low elongation rate are prone to occurring after existing metal composite plates are rolled. According to the technical scheme, the method comprises the following steps of 1, selecting a base plate and a cover plate to manufacture a metal composite plate blank; 2, feeding into a two-high rolling mill a for a first rough rolling to obtain ametal composite plate a, wherein an upper surface, a lower surface and a bonding surface of the metal composite plate a are all unidirectional ripples; 3, feeding into a two-high rolling mill b for asecond rough rolling to obtain a metal composite plate b, wherein an upper surface, a lower surface and a bonding surface of the metal composite plate b are all cross ripples; 4, feeding into a two-high rolling mill c for a flat rolling to obtain a metal composite plate c, wherein an upper surface and a lower surface of the metal composite plate c are both flat surfaces and a bonding surface of the metal composite plate c is a cross ripple; and 5, carrying out heat treatment, straightening, trimming and segmentation to prepare the finished metal composite plate.

Description

technical field

[0001] The invention relates to the technical field of metal composite sheet rolling, in particular to a method for preparing a metal composite sheet by double corrugated roll cross rolling. Background technique

[0002] The metal composite board is a composite board made of two or more metal plates of different materials through pressurization, heating and other methods to make the bonding interface achieve metallurgical bonding. Metal composite panels can give full play to the excellent properties of each component metal, save precious metals, and achieve performance requirements that cannot be met by a single material. They are widely used in aerospace, mechanical power, electronic communications, etc. At present, the methods for producing metal clad plates mainly include explosive clad method, diffusion welding clad method and rolling clad method.

[0003] Explosive compounding method is a method that uses the energy generated when explosives explode as ...
