Embodiment 1

[0031] see figure 1 , the preparation method for the metal composite panel provided by the embodiment of the present invention includes:

[0032] Step S110: heating the second metal plate, so that the temperature of the second metal plate reaches the recrystallization temperature;

[0033] In this embodiment, the heating temperature for heating the second metal plate is 850-1300°C.

[0034] To illustrate this step, the second metal sheet may be sent to a heating furnace for heating.

[0035] Step S120: stacking the heated second metal plate with the first metal plate; wherein, the melting point of the first metal plate is lower than the recrystallization temperature of the second metal plate;

[0036] To illustrate this step, step S120 specifically includes:

[0037] The first metal plate is placed on the surface of the heated second metal plate, and the first metal plate and the second metal plate are pressed together.

[0038] Specifically, the first metal sheet is stack...

Embodiment 2

[0053] The process of preparing aluminum-carbon steel single-sided composite panels by this method includes:

[0054] 1. Processing and heating of steel slabs: the base material is made of Q235, and the size is 40mm×900mm×6000mm. After the upper and lower surfaces of the steel plate are machined, they are cleaned with alcohol to make the surface clean and free of oil. After completion, the steel slab is sent to a heating furnace to be heated to 900°C.

[0055] 2. Aluminum plate processing: The cladding material is made of pure aluminum plate with a thickness of 8mm and a width of 900mm. Uncoil the aluminum coil, and then remove the oxide layer on the upper and lower surfaces with a wire brush, and use an air blower to remove dust to keep the board surface clean.

[0056] 3. Lamination: The aluminum plate is stacked on the surface of the high-temperature steel slab by the guide roller, and pressed by the pinch roller.

[0057] 4. Rolling: Roll the pressed slab to 10mm in 6 pa...

Embodiment 3

[0060] The process of preparing aluminum-carbon steel-aluminum double-sided composite panels by this method includes:

[0061] 1. Processing and heating of steel slabs: the base material is made of 304 stainless steel, and the size is 20mm×800mm×6000mm. After the upper and lower surfaces of the stainless steel plate are machined, they are cleaned with alcohol to make the surface clean and free of oil. After completion, the stainless steel plate is sent to the heating furnace to be heated to 1000°C.

[0062] 2. Aluminum plate processing: The cladding material is prepared from two volumes of pure aluminum plates with a thickness of 6mm and a width of 800mm. Uncoil the aluminum coil, and then remove the oxide layer on the upper and lower surfaces with a wire brush, and use an air blower to remove dust to keep the board surface clean.

[0063] 3. Lamination: The aluminum plate is stacked on the upper and lower surfaces of the high-temperature stainless steel plate through the gui...

Abstract

The invention discloses a preparation method for a metal composite plate. The preparation method comprises the steps that a second metal plate is heated to enable the temperature of the second metal plate to reach a recrystallization temperature; the heated second metal plate is overlapped with a first metal plate, wherein the melting point of the first metal plate is lower than the recrystallization temperature of the second metal plate; the overlapped plates are rolled to obtain the metal composite plate. According to the preparation method, due to the fact that the second metal plate is firstly heated separately to enable the temperature of the second metal plate to reach the recrystallization temperature and then the room-temperature first metal plate is overlapped with the high-temperature second metal plate, the deformation difficulty of the second metal plate is greatly reduced, strong work hardening cannot occur and can be eliminated through subsequent dynamic recovery and dynamic recrystallization , and the processability of the metal composite plate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a preparation method 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 single metal components, metal composite panels after rational design and combination combine the respective advantages of metal components, and can obtain mechanical, physical and chemical properties that single metals do not have. For example, the aluminum-steel composite panel combines the advantages of high strength, easy cleaning of steel and light weight, low price, excellent electrical conductivity and thermal conductivity of aluminum, and has been widely used in aviation, aerospace, machinery, chemical industry, medical treatment, food and other fields. Applications. However, due to the large performance differences betwee...
