Abstract
The invention discloses a kind of powered release technique of black diamond, the release technique is：When synthesis pressure is more than 60MPa, synthesis pressure and power press 4：1.5 pro rates carry out release, and discharge rate is 0.24 0.3MPa/s；When synthesis pressure is less than or equal to 60MPa, synthesis pressure and power press 3:1 pro rate carries out release, and discharge rate is 0.24 0.3MPa/s.The beneficial effects of the invention are as follows：Cooling unloading is carried out to black diamond by the release ratio of the present invention, it is to avoid traditional diamond directly unloads the excessive phenomenon of deflation big gun, top hammer consumption of initiation, effectively reduces production cost, and can improve product qualification rate and yield.
Description
Technical field
The present invention relates to a kind of powered release technique of black diamond, belong to superhard material synthesis technical field.
Background technology
Synthesizing black diamond is needed than synthesizing the higher synthesis pressure of normal diamond and temperature, and synthesis pressure is too high and temperature
Spending high any one factor can all cause press to unload deflation big gun phenomenon after cooling down, and top hammer consumption is excessive, and production cost is higher.
Therefore, common diamond cooling unloading process has not adapted to the production needs of black diamond completely.
The content of the invention
In order to overcome drawbacks described above, the invention provides a kind of powered release technique of black diamond.
To achieve these goals, the technical scheme is that：A kind of powered release technique of black diamond, it is described to unload
Pressure technique is：When synthesis pressure is more than 60MPa, synthesis pressure and power press 4：1.5 pro rates carry out release, and discharge rate is
0.24-0.3MPa/s；When synthesis pressure is less than or equal to 60MPa, synthesis pressure and power press 3:1 pro rate carries out release, unloads
Load speed is 0.24-0.3MPa/s.
The beneficial effects of the invention are as follows：Cooling unloading is carried out to black diamond by the release ratio of the present invention, it is to avoid
Traditional diamond directly unloads the excessive phenomenon of deflation big gun, top hammer consumption of initiation, effectively reduces production cost, and energy
Improve product qualification rate and yield.
Brief description of the drawings
Fig. 1 is process curve figure of the invention.
Embodiment
Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
In the description of the invention, it is necessary to explanation, term " " center ", " on ", " under ", "left", "right", " vertical ",
The orientation or position relationship of the instruction such as " level ", " interior ", " outer " be based on orientation shown in the drawings or position relationship, merely to
Be easy to the description present invention and simplify description, rather than indicate or imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not considered as limiting the invention.In addition, term " first ", " second ",
" the 3rd " is only used for describing purpose, and it is not intended that indicating or implying relative importance.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
To be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected to by intermediary, Ke Yishi
The connection of two element internals.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this
Concrete meaning in invention.
The powered release technique of a kind of black diamond as shown in Figure 1, the release technique is：Synthesis pressure is more than
During 60MPa, synthesis pressure and power press 4：1.5 pro rates carry out release, and synthesis pressure often reduces 4MPa, power reduction
1.5KW, discharge rate is 0.24-0.3MPa/s；When synthesis pressure is less than or equal to 60MPa, synthesis pressure and power press 3:1 ratio
Distribution carries out release, and synthesis pressure often reduces 3MPa, power reduction 1KW, and discharge rate is 0.24-0.3MPa/s.
The application unloads ratio by allocating between synthesis pressure and power, effectively solve and closed under superhigh-temperature and-pressure
It is deflation big gun occurred, the top hammer loss phenomenon such as excessive to carry out cooling unloading into black diamond, greatly reduces production
Cost, improves product qualification rate and quality.
Technical scheme is not limited to the limitation of above-mentioned specific embodiment, and every technique according to the invention scheme is done
The technology deformation gone out, each falls within protection scope of the present invention.
