[0002] Metal composite materials have broad application prospects in the fields of aerospace, automobiles, electricity, electronics, etc. For example, copper-aluminum composite materials combine the high conductivity of copper and the lightweight characteristics of aluminum, and can be used to manufacture high-performance wires and cables and radiators; while steel-aluminum composite materials have excellent strength and corrosion resistance and can be used to manufacture automobile bodies and structural parts. Casting and rolling of metal composite materials is an efficient, energy-saving and environmentally friendly forming process. In the existing technology, casting and rolling equipment is mostly used for the production of small materials of a single metal or alloy, such as the casting and rolling production of gold bars. It is not suitable for continuous casting and rolling production of metal composite materials (such as copper-aluminum composite materials). In addition, existing casting and rolling equipment is used to produce wide plates, and there is no related equipment for producing narrow-band metal composite materials. Utility Model Content

[0004] The technical solution of the utility model is achieved in this way:
[0005] A continuous casting and rolling device for a metal composite material comprises a first casting roller, a second casting roller and a pouring channel for pouring an upper layer of metal liquid. The first casting roller and the second casting roller are arranged in parallel and the roller surfaces are adjacent to each other. An annular groove is circumferentially concavely provided on the roller surface of the first casting roller. The inner cavity of the first casting roller is connected to a water cooling system. An annular protrusion is circumferentially convexly provided on the roller surface of the second casting roller at a position corresponding to the annular groove. The space between the annular groove and the annular protrusion serves as a casting and rolling channel. The pouring channel is obliquely arranged on one side of the first casting roller, and the discharge end of the pouring channel extends to the input end of the casting and rolling channel.

[0026] Embodiment 1
[0027] See also Figures 1 to 3 A continuous casting and rolling device for a metal composite material comprises a first casting roll 1, a second casting roll 2 and a pouring channel 3 for pouring an upper metal liquid. The first casting roll 1 and the second casting roll 2 are arranged in parallel and the roll surfaces are adjacent to each other. An annular groove 11 is circumferentially concavely provided on the roll surface of the first casting roll 1. The inner cavity of the first casting roll 1 is connected to a water cooling system. An annular protrusion 21 is circumferentially convexly provided on the roll surface of the second casting roll 2 at a position corresponding to the annular groove 11. The space between the annular groove 11 and the annular protrusion 21 serves as a casting and rolling channel 4. The pouring channel 3 is obliquely arranged on one side of the first casting roll 1, and the discharge end of the pouring channel 3 extends to the input end of the casting and rolling channel 4.
[0028] It should be noted that the metal composite material is composed of two metals, the metal located on the upper layer of the metal composite material is called the upper metal, and the metal located on the lower layer of the metal composite material is called the lower metal. The upper metal liquid is the liquid upper metal. The metal composite material of the present application takes the copper-aluminum composite material as an example, the upper metal is aluminum, and the lower metal is copper. The first casting roller 1 and the second casting roller 2 rotate in opposite directions. In this embodiment, the first casting roller 1 rotates counterclockwise, and the second casting roller 2 rotates clockwise. During the rotation, the annular protrusion 21 of the second casting roller 2 extends into the annular groove 11 of the first casting roller 1 at the mutually adjacent position of the roller surfaces of the first casting roller 1 and the second casting roller 2. The space between the annular groove 11 of the first casting roller 1 and the annular protrusion 21 of the second casting roller 2 is the casting channel 4. The aluminum liquid enters the casting channel 4 from the pouring channel 3, and the copper strip enters the casting channel 4 at the same time. Since the inner cavity of the first casting roller 1 is connected to the water cooling system, the aluminum liquid instantly crystallizes and solidifies when it contacts the first casting roller 1 and is fixed on the surface of the copper strip to form a copper-aluminum composite strip material. Therefore, the continuous casting and rolling device can continuously pour the upper metal liquid into the casting and rolling channel 4 through the pouring channel 3, and at the same time the solid lower metal continuously enters the casting and rolling channel 4, so as to continuously cast and roll out the metal composite material, and is suitable for the continuous casting and rolling of the metal composite material. Moreover, the annular groove 11 of the first casting roller 1 and the annular protrusion 21 of the second casting roller 2 can be set according to the width of the narrow-strip metal composite material, and can be used for the production of narrow-strip metal composite materials.
[0029] It should be noted that the aluminum liquid begins to crystallize and solidify after contacting the first casting roller 1. At this time, the aluminum liquid that has been crystallized and solidified can form a barrier to the aluminum liquid that is subsequently poured into the casting channel 4, so the aluminum liquid will not flow forward along the copper strip. The main purpose of the water cooling system is to reduce the temperature of the first casting roller 1 during the casting process so that the molten metal can crystallize at the moment of contacting the first casting roller 1. The water cooling system is a prior art. For example, a water inlet and a water outlet are designed on the first casting roller 1 for the circulation of cooling water. The water cooling system connects the water inlet and the water outlet through two water pipes respectively. The water cooling system supplies water to the water inlet and recovers the water flowing out of the water outlet. Of course, the structure of other water cooling systems in the prior art can be adopted, which will not be repeated here.
[0030] In this embodiment, the first casting roller 1 and the second casting roller 2 are arranged vertically in parallel, the copper strip enters the casting channel 4 horizontally, the aluminum liquid is poured into the casting channel 4 horizontally, and the copper-aluminum composite strip material completed by casting is output horizontally from the casting channel 4, that is, the entire casting process is carried out horizontally.
[0031] Preferably, a first guide mechanism 5 is provided on one side of the input end of the casting and rolling channel 4. The first guide mechanism 5 has a first guide groove 51. The first guide groove 51 is used to guide the solid lower layer metal into the casting and rolling channel 4 to prevent the solid lower layer metal from being offset before entering the casting and rolling channel 4, so that the solid lower layer metal can be better aligned to enter the casting and rolling channel 4.
[0032] Preferably, a second guide mechanism 6 is provided at one side of the output end of the casting channel 4, and the second guide mechanism 6 has a second guide groove 61, and the metal composite material output from the casting channel 4 passes through the second guide groove 61. By providing the second guide mechanism 6, the metal composite material output from the casting channel 4 is prevented from being deviated, so that the stability of the metal material passing through the casting channel 4 can be maintained during continuous casting.
[0033] Preferably, in order to prevent the aluminum liquid flowing through the pouring channel 3 from crystallizing, a heating component 7 for heating the pouring channel 3 is provided on the back side of the pouring channel 3. The heating component 7 heats the pouring channel 3, thereby preventing the aluminum liquid flowing through the pouring channel 3 from cooling down and preventing the aluminum liquid from crystallizing on the pouring channel 3. Moreover, for the narrow strip metal composite material, the width of the casting channel 4 is relatively narrow, and the width of the casting channel 3 is substantially the same as the width of the casting channel 4, so the width of the casting channel 3 is also relatively narrow, and the speed at which the metal liquid flows through the casting channel 3 is relatively fast, so it will not crystallize on the casting channel 3. The flow speed of the metal liquid can be adjusted by adjusting the inclination angle of the pouring channel 3. The more inclined the pouring channel 3 is, the faster the flow speed of the metal liquid is. Of course, the inclination angle of the pouring channel 3 cannot be too large to avoid interfering with the rotation of the first casting roller 1 or the metal liquid does not flow into the casting channel 4 along the pouring channel 3 after being poured into the pouring channel 3.
[0034] In this embodiment, the heating temperature of the heating assembly 7 is 680-700° C. Of course, the heating temperature may also adopt different temperature values to ensure that the upper layer of the metal liquid flowing through the pouring channel 3 does not cool down.
[0035] Preferably, one side of the first casting roller 1 and the second casting roller 2 is provided with a spraying assembly (not shown in the figure) for spraying a release agent onto the roller surface. By spraying the release agent, it is ensured that the aluminum liquid crystals will not adhere to the first casting roller 1 or the second casting roller 2, and the aluminum liquid can be better separated from the casting roller after crystallization.
[0036] In some other embodiments, one side of the first casting roller 1 and the second casting roller 2 is provided with a spraying assembly (not shown in the figure) for spraying fire onto the roller surface, so that the sprayed flame melts and solidifies the aluminum liquid adhering to the first casting roller 1 or the second casting roller 2 to avoid affecting the subsequent casting and rolling of the composite metal.
[0037] Preferably, the roller surfaces of the first casting roller 1 and the second casting roller 2 are both coated with a carbide layer to further prevent the aluminum liquid from adhering to the roller surface of the first casting roller 1 or the second casting roller 2 and affecting the subsequent casting of the composite metal.
[0038] Embodiment 2
[0039] See also Figure 4 In this embodiment, the continuous casting and rolling device of the metal composite material also includes a frame 8, and the first casting roll 1, the second casting roll 2, the first guide mechanism 5 and the second guide mechanism 6 are all installed on the frame 8.
[0040] Embodiment 3
[0041] The direction of casting and rolling can be selected according to production requirements, see Figure 5 The present embodiment is different from the first embodiment in that the first casting roller 1 and the second casting roller 2 are arranged horizontally in parallel, the copper strip enters the casting channel 4 vertically, the aluminum liquid is poured into the casting channel 4 vertically, and the copper-aluminum composite strip material after casting is output vertically from the casting channel 4, that is, the entire casting process is vertical. Horizontal movement saves more height of the production workshop than vertical movement, and compared with horizontal movement, the vertically poured aluminum liquid will also overflow along the copper strip instantly, and the aluminum crystallized on the copper strip is relatively uneven.
[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
