Embodiment 1

[0033] S1, such as figure 1 As shown, a T2 copper plate with a size of 100mm×20mm×1.5mm is selected as the substrate 1, and two 1060 pure aluminum plates with a size of 100mm×20mm×2.5mm are selected as the cladding plate 2, and the above-mentioned substrate 1 and cladding plate 2 are The surface to be bonded is polished with a wire brush grinder until fresh metal leaks from the surface, then the polished metal surface is cleaned with alcohol, and finally laminated in the order of "aluminum on the upper cladding plate - copper on the base plate - aluminum on the lower cladding plate" put, and bind the head and tail of the stacked blanks with iron wires to make metal composite panel blanks 3;

[0034] S2, refer to figure 2 , the obtained metal clad plate blank 3 is sent to the two-roll rolling mill a for the first rough rolling, the two-roll rolling mill a of this step adopts two corrugated rolls a with the same direction of corrugation, the reduction rate is 50%, rolling The...

Embodiment 2

[0047] S1. Select a 1060 pure aluminum plate with a size of 100mm×20mm×2.5mm as the substrate 1, and select two T2 red copper plates with a size of 100mm×20mm×1.5mm as the cladding plate 2. Combine the surface with a wire brush grinder for grinding until fresh metal leaks from the surface, then clean the polished metal surface with alcohol, and finally stack it in the order of "upper cladding copper - substrate aluminum - lower cladding copper" , binding the head and tail of the stacked blanks with iron wires to make a metal composite plate blank 3;

[0048] S2. Send the obtained metal composite plate blank 3 into the two-roll rolling mill a for the first rough rolling. The two-roll rolling mill a in this step adopts two longitudinal corrugated rolls a with the same corrugation direction, and the reduction rate is 50%. The rolling speed is 0.15m / s, and the plate obtained by the first rough rolling is as follows: Figure 8 As shown, this step is processed to obtain a metal com...

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 ...
