(7) finishing: adopt multiple roll planer to the laminated metal coiled strip of step (6) rolling, put volume, leveling, rolling, repeatedly repeat this process, until laminated metal band leveling.
(8) divide bar: put volume, cut unnecessary edge, batch as volume shape, obtain the Cu/Mo/Cu laminated metal coiled strip meeting thickness ratio requirement.
In a particular embodiment of the present invention, described copper winding is pure copper material, and molybdenum winding is selected from pure molybdenum or molybdenum-copper material. Molybdenum-copper is Mo70Cu��Mo60Cu or Mo50Cu��
Specifically, entering process furnace and be specially described in step (2): copper winding enters 600-900 DEG CJia hot temperature district, molybdenum winding enters 800-1200 DEG CJia hot temperature district, time as identical with molybdenum winding Heating temperature in copper winding, enter and same adds hot temperature district, at 3-20m3Under the protection of/h ammonolysis craft gas or hydrogen, entering 45-150 ton two-roller mill, distortion amount is 30-70% simultaneously, with 1-10m/min roll speed, three-layer metal rolling is combined into laminated metal band and batches as volume shape.
Further, anneal described in step (5) is: annealing furnace temperature 600-900 DEG C, leads to into 5-10m3/ h ammonolysis craft gas or hydrogen shield, tape running speed is 3-10m/min.
The Cu/Mo/Cu laminated metal coiled strip intermediate core layer adopting above method obtained is that pure Mo or MoCu alloy is (such as Mo70Cu��Mo60Cu��Mo50Cu etc.), top and bottom are pure Cu layer, and upper and lower two layers of copper layer thickness difference are less than 0.03mm. The Cu:Mo:Cu thickness degree proportioning of described Cu/Mo/Cu laminated metal coiled strip is 1:1:1��1:6:1.
Compare traditional tungsten copper (WuCu), molybdenum copper (MoCu) metal composite, copper molybdenum copper (Cu/Mo/Cu) laminated metal thermal conductivity is higher, and copper/molybdenum copper/copper (Cu/MoCu/Cu) laminated metal, because of the net distribution in molybdenum of copper in molybdenum-copper, its thermal conductivity is higher.
Mo or MoCu layer has lower thermal expansivity, the performance that the good thermal conductivity of Cu layer tool, good electric conductivity and lower contact resistance etc. are excellent, the expansion system of Cu/Mo/Cu or Cu/MoCu/Cu lamellar composite coiled strip and thermal conductivity can regulate according to three layer thickness ratios of design. Usual thickness ratio 1:1:1,1:2:1,1:3:1,1:4:1,13:74:13.
Raw material Cu winding, Mo or MoCu winding, Cu winding inherently have certain length, and by rolling reductions, thickness subtracts thin, and under the effect of the power of batching, coiled strip alongst extends, less along spreading of width. So after Cu winding, Mo or MoCu winding, Cu winding combined by continuously hot rolling, finished product length can reach the three-layer metal compound coiled strip of tens of rice and even hundred meters.
Product prepared according to the methods of the invention, is conducive to improving production efficiency, reduces production cost, ensure quality product consistence, and applicable mass-producing is produced continuously, compensate for the domestic blank that cannot provide such long ribbon shape material, has good production application and is worth.
