Description of the Invention: [Technical Field] The present invention relates to a laminated metal and a method of manufacturing the same, and more particularly to a continuously produced composite laminated metal and a method of manufacturing the same. [Prior Art] When the conventional lock alloy is used in the transportation industry, the surface needs to undergo complicated surface formation/film treatment, micro-arc oxidation and subsequent coating, which is generally costly, and the surface passivation film is damaged. The resistance to the instrument will be reduced, and subsequent repairs will be inconvenient. There are still doubts in applications such as automotive panels that require weather resistance. Therefore, an improvement method is to laminate a face material (e.g., steel or inscription) to the surface of a magnesium alloy, as described below. Referring to Figure 1, a schematic view of a conventional roll-rolling composite is shown. First, a magnesium roll 11 and an aluminum roll 12 are provided. Next, the magnesium roll 11 and the aluminum roll 2 are unwound to provide a lock material 13 and an aluminum material 14, respectively. The weathered material 13 has an upper surface 131 having a lower surface 141. Next, the magnesium material π and the aluminum material 14 pass through a first steel brush wheel 15 and a second steel brush wheel 16, respectively. The first steel brush wheel 15 brushes away the oxide layer of the upper surface 131 of the weathered material 13 and forms a roughened surface. The second steel brush wheel 16 brushes the oxide layer of the lower surface 141 of the aluminum material 14 and forms a rough sugar surface. Next, the magnesium material 13 and the aluminum material 14 are fed to a rolling device 17. The rolling device 17 includes two rollers 171, 172'. After the lower surface 141 of the aluminum material 14 contacts the upper surface 131 of the magnesium material 13, the rollers 171, 172 roll the aluminum material 14 and the magnesium material 13 to form A composite metal 18. Finally, the composite metal 18 is continuously wound up to form a composite metal roll 19. 136412.doc 201023989 The disadvantages of the conventional rolling-rolling technique are as follows: 'Because the system is rolled at normal temperature, the magnesium material 13 is rolled at room temperature (4) + H (four) coffin u and the material 14 Can not be tightly combined, as shown in Figure 2. It can be seen from the second that in the composite metal 18, there are still many gaps between the weathered material 13 and the finished material 14. Since the presence of such gaps causes potential difference corrosion in the regions a, B, C, D, E, the corrosion resistance of the composite metal is good.

Step S102 is to perform a continuous casting process so that the first liquid metal 21 continues to form a first metal plate 23. In this embodiment, the material of the first metal plate 23 is magnesium or a magnesium alloy. The first metal plate 23 has a first surface 231. Preferably, the first metal plate 23 passes through a first steel brush wheel 25 for scraping off the oxide layer on the first surface 231 of the first metal plate 23, and The first surface 231 of the first metal plate 23 forms a first rough surface. Preferably, the surface of the first rough surface has a roughness of Ra2 10 μm. In step S103, a second metal plate 24 is provided. In the embodiment, the material of the first metal plate 24 is made of Ming, Ming alloy, titanium, titanium alloy or steel. The manner in which the second metal plate 24 is provided includes, but is not limited to, the following two. In the first mode, a second metal coil 22 is first provided. Next, the second metal coil 22' is unwound to provide the second metal plate 24. In the second mode, first, a second liquid metal (not shown) is provided. Next, a continuous scale process is performed to continue the formation of the second metal sheet 24 by the second liquid metal. The β-thin metal plate 24 has a second surface 241. Preferably, the second metal plate 24 passes through a second steel brush wheel 26'. The second steel brush wheel 26 is used to scrape the second surface 241 of the second metal plate 24 by 136412.doc -8 201023989. The oxide layer is formed such that the second surface 241 of the second metal plate 24 forms a second rough surface. Preferably, the surface roughness of the second rough surface is Ra^10pm. Step S 1 04 is a rolling composite process. In the present invention, before the temperature of the first metal plate 23 drops to its Warm Forming temperature (for example, the temperature drops above its temperature forming temperature, or the temperature drops to its temperature forming temperature range) Internally, the second metal plate 24 is rolled and composited with the first metal plate 23 to form a composite laminated metal 28. For example, the first forming temperature of the first metal plate 23 is 300 ° C to 450 ° C. In the present embodiment, the first metal plate 23 and the second metal plate 24 are fed to a rolling. Extend the device 27. The rolling device 27 includes two rollers 271, 272. When the first surface 231 of the first metal plate 23 contacts the second surface 241 of the second metal plate 24, the rollers 271, 272 roll the second metal The plate 24 and the first metal plate 23' form a composite laminated metal 28. If necessary, more rolls may be provided to roll the second metal plate 24 and the first metal plate 23 a plurality of times. ❿ Finally, the composite laminated metal 28 is continuously wound up to form a composite laminated metal roll 29. Preferably, the rolling step further includes an annealing step 'even if the composite laminated metal 28 is annealed by an annealing device 30' to promote interface diffusion between the second metal plate 24 and the first metal plate 23. 'Making the second metal plate 24 and the first metal plate 23 can be tightly coupled. Referring to Figure 5, a cross-sectional view of the composite laminated metal of the present invention is shown. The composite laminated metal 28 includes a first metal plate 23 and a second metal plate 24. 136412.doc -9- 201023989 The first metal plate 23 is formed by continuous casting. The second metal plate is combined with the first metal plate 23 before the temperature is lowered to the temperature forming temperature by rolling and laminating, and has a diffusion interface therebetween (not shown in the embodiment, the second The metal plate 24 is located on the first metal plate 23, and the material of the first metal plate 23 is magnesium or a town alloy, and the material of the second metal plate is aluminum, aluminum alloy, titanium, titanium alloy or steel. The thickness of the second metal plate 24 is less than or equal to one third of the thickness of the first metal plate 23. The total thickness of the composite laminated metal 28 is greater than or equal to 〇4 mm. Preferably, the composite laminated metal The 28 further includes a third metal plate (not shown), the third metal plate is located under the first metal plate 23, and the third metal plate is combined with the first metal plate 23 by rolling and rolling. And having a diffusion interface therebetween. As can be seen in Fig. 5, the second metal plate 24 is tightly bonded to the first metal plate. Therefore, the internal interface of the composite laminated metal 28 does not have a significant potential difference. In the present invention, when the first metal plate 23 is continuous After the production, the temperature is still in the south temperature state, and it is easy to generate dynamic recrystallization, which can promote the rolling formability and the composite property. At this time, immediately before the temperature of the first metal plate 23 drops to the temperature forming temperature, it is compounded immediately. The second metal plate 24 can obtain better composite strength and productivity, thereby eliminating the weight advantage of the first metal plate 23 (for example, magnesium alloy), and simultaneously solving the first metal plate. 23 (such as magnesium alloy) has the problem of poor corrosion resistance of the original surface, and can reduce the cost of coating and surface treatment. However, the above embodiments are only for explaining the principle and function of the present invention, instead of using 136412.doc -10· 201023989 The invention is not limited by the spirit and scope of the invention, and the scope of the invention should be as described in the appended claims.
