[0044] Refer to Figure 1 and Figure 2 As shown, the embodiments of the present application provide a production equipment for a metal composite strip, including: a conveying device 1, and a heating device 2, a casting device 3, and a rolling device 4 sequentially arranged along the feeding direction of the conveying device 1; wherein, the conveying device 1 is used to sequentially convey a plurality of base materials 7 to the heating device 2, the casting device 3, and the rolling device 4; the heating device 2 is used to heat-treat the plurality of base materials 7; the casting device 3 is used to pour molten metal between any two adjacent base materials 7, and make the solidified casting material 8 metallurgically combined with the base material 7 to form a composite blank; the rolling device 4 is used to roll the composite blank.

[0045] The steps of producing a through-type composite strip using the production equipment for metal composite strips are as follows:

[0046] First, use the conveying device 1 to convey multiple base materials 7 into the heating device 2 for heat treatment. After the heat treatment is completed, the multiple base materials 7 are conveyed by the conveying device 1 to the pouring device 3. The molten metal is injected between two adjacent base materials 7 through the pouring device 3. After the molten metal solidifies, a poured material 8 is formed. The poured material 8 comes into contact with the base material 7 at high temperature and forms a metallurgical bond to form a composite blank.

Among them, the length of the composite strip is (1 - 20) m, the width is (20 - 200) mm, and the thickness is (10 - 100) mm. Of course, it is not limited to this.

[0047] It can be seen that the production equipment for this metal composite strip realizes the automated production of the through-type composite strip, saves manpower, has a simple production process, and high production efficiency. In addition, the production equipment for this metal composite strip is based on pouring metal solution between adjacent base materials 7 to achieve the metallurgical bond of adjacent base materials 7, and after rolling treatment, it has higher strength.

[0048] Among them, optionally, the base material 7 can be copper and copper alloys, and the poured material 8 is silver and silver alloys, aluminum and aluminum alloys.

[0049] The specific structures of the conveying device 1, the heating device 2, the pouring device 3, and the rolling device 4 will be described below:

The conveying device 1 includes a horizontal conveying roller assembly, a first vertical guiding roller assembly 11 and a second vertical guiding roller assembly 12 provided on the frame 5. Among them, along the feeding direction of the conveying device 1, the horizontal conveying roller assembly and the first vertical guiding roller assembly 11 are arranged upstream of the heating device 2, and the second vertical guiding roller assembly 12 is arranged downstream of the heating device 2, and the second vertical guiding roller assembly 12 is located between the heating device 2 and the pouring device 3.

[0051] According to the above-described structure, the horizontal conveying roller assembly is used to convey multiple base materials 7 to the first vertical guiding roller assembly 11. The first vertical guiding roller assembly 11 is used to guide the multiple base materials 7 before entering the heating device 2 to ensure that the widths of two adjacent base materials 7 remain unchanged. The second vertical guiding roller assembly 12 is used to guide the multiple base materials 7 before entering the pouring device 3 to ensure that the widths of two adjacent base materials 7 remain unchanged.

[0052] Among them, the lateral spacing between two adjacent vertical guide rollers is equal to the width of the substrate 7, and the width of the substrate 7 is (20 - 100) mm. Of course, it is not limited to this.

[0053] In this embodiment, preferably, the horizontal conveying roller assembly includes a plurality of horizontal conveying rollers (not shown in the figure). The plurality of horizontal conveying rollers are arranged in parallel at intervals along the feeding direction of the conveying device 1 and are used to convey a plurality of substrates 7 to the heating device 2.

[0054] As Figure 3 shown, the first vertical guide roller assembly 11 includes a plurality of first vertical guide rollers 111. The plurality of first vertical guide rollers 111 are arranged in parallel at intervals along the width direction of the plurality of substrates 7. Among them, two adjacent first vertical guide rollers 111 can limit the substrate 7 clamped therebetween to ensure that the spacing between two adjacent substrates 7 remains unchanged, especially for the substrate 7 before entering the heating device 2.

[0055] As Figure 4 shown, the second vertical guide roller assembly 12 includes a plurality of second vertical guide rollers 121. The plurality of second vertical guide rollers 121 are arranged in parallel at intervals along the width direction of the plurality of substrates 7. Among them, two adjacent second vertical guide rollers 121 can limit the substrate 7 clamped therebetween to ensure that the spacing between two adjacent substrates 7 remains unchanged, especially for the substrate 7 before entering the pouring device 3.

[0056] In this embodiment, preferably, as Figure 1 and Figure 2 shown, the heating device 2 is a tunnel heating furnace and is arranged on the frame 5.

[0057] According to the structure described above, the tunnel heating furnace can heat the longer substrate 7 while conveying it forward to meet the actual needs.

[0058] Among them, the preheating temperature of the substrate 7 in the tunnel heating furnace is 300 - 500 °C, the speed of the conveyor belt 21 of the tunnel heating furnace is (0.1 - 0.3) m / s, and a protective gas, such as any one of nitrogen, argon, hydrogen, and ammonia decomposition gas, is passed through the tunnel heating furnace.

[0059] In this embodiment, preferably, as Figures 5 to 8 shown, the production equipment for the metal composite strip further includes a support frame 6, and the pouring device 3 is arranged on the support frame 6.

[0060] The pouring device 3 includes a main body 31, a pouring pool 32 arranged on the main body 31, and a plurality of diversion members 33. Among them, the main body 31 forms a molding cavity 311; the pouring pool 32 is annular; the inlet end of the diversion member 33 is connected to the internal hollow part of the pouring pool 32, and the outlet end of the diversion member 33 is connected to the molding cavity 311 of the main body 31.

[0062] According to the structure described above, first, a protective gas is introduced into the forming cavity 311 of the main body 31, and then the molten metal is slowly and continuously poured into the pouring pool 32. The molten metal then enters the forming cavity 311 through the guiding member 33. The outlet end of the guiding member 33 is exactly located in the forming groove surrounded between two adjacent base materials 7. The molten metal fills the forming groove along the length direction of the base material 7, and then forms a casting material 8 after solidification. The casting material 8 comes into contact with the base material 7 at high temperature and forms a metallurgical bond to form a composite blank.

[0063] Among them, the main body 31, the pouring pool 32, and the guiding groove member are all made of high-purity graphite. The main body 31 is in a cuboid shape, with a length of (1500 - 2000) mm, a width of (50 - 200) mm, and a protective gas can be introduced into it, such as any one of argon, carbon dioxide, hydrogen, and ammonia.

[0064] In this embodiment, preferably, as Figure 7 shown, the guiding member 33 is formed with a conical guiding channel 331, and the guiding channel 331 is tapered from top to bottom along the height direction.

[0065] The guiding channel 331 plays a role in guiding the flow, guiding the molten metal between the two base materials 7 to prevent the molten metal from flowing to other places.

[0066] In this embodiment, preferably, as Figure 1 and Figure 2 shown, the rolling device 4 includes a horizontal roll mechanism 41 and a vertical roll mechanism 42; among them, the number of the horizontal roll mechanisms 41 is two, and the two horizontal roll mechanisms 41 are arranged on opposite sides of the vertical roll mechanism 42, that is, on both sides of the vertical roll mechanism 42 in the feeding direction.

[0067] The composite blank formed after being cast by the casting device 3 is laterally compressed under the rolling of the vertical roll mechanism 42 while being pinch-fed by one of the horizontal roll mechanisms 41 to form a through-type composite strip. Then, as needed, the through-type composite strip can be further pressed down by the other horizontal rolling mechanism until the target size is reached.

[0068] Among them, optionally, the horizontal roll mechanism 41 includes a first support frame 411 and two horizontal rolls 412 rotatably arranged on the first support frame 411. The two horizontal rolls 412 are spaced along the length direction perpendicular to the composite blank, and along the feeding direction of the conveying device 1, the linear velocity of the horizontal roll 412 located downstream is greater than that of the horizontal roll 412 located upstream, so as to form tension on the strip;

[0069] The vertical roll mechanism 42 includes a second support frame 421 and two vertical rolls 422 rotatably arranged on the second support frame 421. The two vertical rolls 422 are spaced along the width direction perpendicular to the composite blank, and the deformation amount of the vertical roll 422 is 10%-50%.

[0073] Step 102: Convey the preheated plurality of base materials 7 to the pouring device 3 through the conveying device 1, and the metal melt is injected between two adjacent base materials 7 through the pouring device 3. After the metal melt solidifies, a poured material 8 is formed. The poured material 8 contacts the base material 7 at high temperature and forms a metallurgical bond to form a composite blank;

[0074] Step 103: Convey the composite blank to the rolling device 4 through the conveying device 1 for rolling to form a through-type composite strip.

[0075] The above production process is simple, has high production efficiency, and because the metal solution is poured between adjacent base materials 7 to achieve the metallurgical bond of adjacent base materials 7, the strength is higher.

[0076] In this embodiment, preferably, before step 101, the following steps are further included: sequentially passing a plurality of blanks through slitting and width fixing, degreasing, pickling, and cleaning treatments to form a plurality of base materials 7.

[0079] Step 201: Successively subject multiple blanks to slitting for width determination, degreasing, pickling, and cleaning treatments to form multiple base materials 7;

[0080] Step 202: Feed the base material 7 successively into the heating device 2 for preheating through the horizontal conveying rollers of the horizontal conveying roller assembly and the first vertical guiding roller 111 of the first vertical guiding roller assembly 11. The conveyor belt 21 of the heating device 2 feeds the preheated base material 7 into the pouring device 3 through the second vertical guiding roller 121 of the second vertical guiding roller assembly 12;

[0081] Step 203: Pour the melted and static metal melt through the runner of the pouring device 3. The outlet end of the runner is located between two adjacent base materials 7. After the metal melt solidifies, a poured material 8 is formed. The poured material 8 contacts the base material 7 at high temperature and forms a metallurgical bond;

[0082] Step 204: Feed the poured composite blank between the vertical rollers 422 of the vertical roller mechanism 42 under the pinch of the horizontal rollers 412 of one of the horizontal roller mechanisms 41, so that it is laterally compressed to form a through-type composite strip;

[0083] Step 205: Continue to press down the through-type composite strip with the horizontal rollers 412 of the other horizontal roller mechanism 41 as needed until the target size.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
