Melt applies ultrasonic activation, makes to be uniformly mixed；
Casting: titanium alloy solution is pressed 1500 DEG C~1660 DEG C of casting temperature, the work of 60~65mm/min of casting speed by S2
Skill carries out just casting, comes out of the stove air-cooled, and it is 300mm × 1219mm × 4000mm titan alloy casting ingot that specification is sawed into after railway carriage；Institute
Titan alloy casting ingot is stated by 6 fire time forgings, wherein carrying out three fire time forgings more than transformation temperature, carries out three piers four altogether and pull out to fall circle,
Satin when pier pulls out is than control between 1.3-1.7；The finish-forging when temperature is 970 DEG C~990 DEG C, obtains casting skin bar；
S3, hot rolling: casting skin bar carries out the coiled material that hot rolling is 9.0mm at 800~850 DEG C；
S4, intermediate annealing: the intermediate annealing at 700~720 DEG C；
S5, cold rolling and finish rolling: it using disposable volume under pressure up to 60%, allows the crystalline solid of elongation, passes through biggish volume under pressure
Again it is broken；Then 500-600 DEG C of annealing crystallization again, the tissue resorption heat nodularization of elongation, then apply 30% drafts, it allows
Crystalline substance material elongates；While guaranteeing high-intensitive, deformation texture and the Deformation structure of balance are kept, has reduced group fabric line to the greatest extent
Occur, to obtain highlighted black mirror effect；
Wherein, in cold rolling and finishing stands, activated carbon powder, then air-cooled 8 hours are sprayed in the surface of casting skin coiled material, it is cooling
When activated carbon powder realize the unstable metal impurities of titanium alloy coiled material reduction:
Fe3O4+ C=3FeO+CO ↑
FeO+C=Fe+CO ↑
2CuO+C=2Cu+CO2↑
2ZnO+C=2Zn+CO2↑。
Can prevent titanium alloy strip surface from impurity occur in this way and be oxidized phenomenon, substantially increase the anticorrosive of black titanium and
Anti-scratch colored performance, and after leaving hot environment, also it can keep for a long time stable.
S6, continuous straightening: obtain high intensity can mirror surface titanium alloy strip 200, which can mirror surface titanium alloy strip 200
Thickness and width be 80~200±1Mm*1225mm, cross section structure has partial size of different sizes, as shown in figure 4, including
First surface layer 201, the second surface layer 202, first time surface layer 203, second of surface layer 204, intermediate laminboard layer 205, first table
Layer 201 and the second surface layer 202 about intermediate laminboard layer 205 symmetrically, first time surface layer 203 and second of surface layer 204 about centre
Laminboard layer 205 is symmetrical, and first surface layer 201, the brilliant of the second surface layer 202 expect that partial size is less than first time surface layer 203, second of surface layer
204 brilliant material partial size, first time surface layer 203, second of surface layer 204 brilliant material partial size be less than intermediate laminboard layer 205, wherein
The thickness on the first surface layer 201 and the second surface layer 202 is greater than 200.
By continuous straightening, this can mirror surface titanium alloy strip surface it is very fine and close, finish is good, and does not have band,
The surface-brightening such as mirror of entire band.
S7, finishing form the shape for watch case of selling.The formation of finishing at least precise NC lathe processing, CNC
Lathe in machining, computer Milling Machining, the processing of computer gong, chemical attack processing etc..
In conclusion design focal point of the invention is, due to having invented black titanium technology, allow titanium material by high-temperature process
Self-assembling formation black afterwards is shortening the production time, and while improving production efficiency, and energy output wearability is strong, anticorrosive and anti-
The high-quality black titanium material scratched, improves enterprise in the core competitiveness of horological industry.Meet enterprise constantly to pursue being outstanding product
The corporate culture of matter surely allows enterprise with faster, more surely, higher paces move towards industry front end.
