Embodiment 1

[0034] see figure 1 , the preparation method for the metal composite panel provided by the embodiment of the present invention includes:

[0035] Step S110: heating the substrate and the superstrate;

[0036] To illustrate this step, step S110 specifically includes:

[0037] The substrate and the superstrate are heated by a heating device.

[0038] What needs to be explained here is that the embodiments of the present invention can freely choose isothermal heating or non-isothermal heating for the substrate and the cover plate according to the needs, which satisfies the heating requirements of various materials when they are combined, and is therefore suitable for use between various materials. Combination improves the practicability of the embodiments of the present invention.

[0039] In this embodiment, the substrate and the superstrate are heated to 700-1200°C.

[0040] In order to ensure that the size of the plate is regular, the length and width are consistent, and t...

Embodiment 2

[0067] Adopt this method to prepare the steps of aluminum-carbon steel single-sided composite panel as follows:

[0068] 1. Substrate processing and heating: The substrate is prepared by Q235, and the substrate is machined to make the substrate size 90mm×900mm×8000mm. After the processing is completed, the surface is cleaned to make it clean and free of rust and oil. Then the substrate is sent into the heating furnace to be heated to 1100°C, and then it is taken out of the furnace for high-pressure water descaling treatment.

[0069] 2. Processing of clad metal coils: Uncoil and cut pure aluminum coils with a thickness of 10mm to make the width 900mm; then use a wire brush to clean the oxide layer on the surface of the aluminum coils, roughen the surface of the aluminum coils and take them up for later use.

[0070] 3. Base plate and cladding plate heating and scale reduction: after the base plate is heated and descaled, it is sent into the reduction furnace through the roller...

Embodiment 3

[0075] Adopt this method to prepare the step of copper-aluminum single-sided composite board as follows:

[0076] 1. Coil processing of metal raw materials: Uncoil and cut the pure copper coil with a thickness of 15mm and the pure aluminum coil with a thickness of 15mm respectively, so that the width of the pure copper coil and pure aluminum coil is 950mm; then use a wire brush to clean the two coils. remove the oxide layer on the surface of each strip, roughen the surface and take it up for later use.

[0077] 2. Heating of metal raw coils and reduction of scale: heat two coils through heating equipment, and introduce them into the reduction furnace through the introduction device. Next, the high-temperature reducing gas is passed into the reduction furnace, so that the high-temperature reducing gas and the residual oxides on the surfaces of the two coils undergo a reduction reaction. Among them, the reducing gas is H 2 Gas, the gas temperature is 750°C.

[0078] 3. Lamina...

Abstract

The invention discloses a preparation method and a preparation device for a metal composite plate. The method comprises the following steps: heating a base plate and a shroud plate; performing reduction reaction on the surfaces of the base plate and the shroud plate which are heated; stacking the base plate and the shroud plate which are subjected to reduction reaction; rolling the stacked plates to obtain the metal composite plate. The surfaces of the base plate and the shroud plate which are heated are subjected to reduction reaction, so that oxides on the surfaces of the base plate and the shroud plate are removed, and the influence of the interface oxides on compounding is eliminated during compounding.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a preparation method and device for metal composite panels. Background technique [0002] The metal composite panel is a new type of material compounded by two or more metal materials with different properties through a special process. Compared with a single metal component, the metal composite plate after rational design and combination combines the respective advantages of the metal components, and can obtain mechanical, physical and chemical properties that a single metal does not have. Currently, it has been used in aviation, aerospace, machinery, Chemical, medical, food and other fields have been widely used. However, due to the large performance difference between materials, the preparation of metal composite panels is difficult. The current preparation methods mainly include explosive composite method, brazing composite method and rolling composite method. ...
