Abstract
The invention discloses a kind of Cubic boron nitride current drop prevention technology, adjusted accordingly by the involutory success ratio of stagnation point of chemical reaction in production, avoid the stage of power down stream, meet the heat-up time of normal synthesis needs, ensure the Quality and yield of product simultaneously, reduce the generation of useless block.
Description
Technical field
The present invention relates to superhard material treatment process technical field, particularly relate to a kind of Cubic boron nitride current drop prevention technology.
Background technology
In artificial cubic boron nitride production process, because its active chemical reaction causes cubic boron nitride frequently to occur power down flow phenomenon in process of growth, power down flow phenomenon can cause damaging top hammer otherwise because of power down miscarriage raw heat-up time less than and produces useless block or reduction product quality.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Cubic boron nitride current drop prevention technology.
To achieve these goals, technical scheme of the present invention is: a kind of Cubic boron nitride current drop prevention technology, and described step is as follows:
1), power bust 0.2-0.5KW will be synthesized in the cubic boron nitride building-up reactions the fiercest period;
2), treat the chemical reaction that cubic boron nitride building-up reactions is the fiercest after, synthesis power, after 30 seconds, is heightened 0.8-12.KW by smooth running,
3), whole process synthesis final pressure is not done and is changed.
The invention has the beneficial effects as follows: the involutory success ratio of stagnation point of Cubic boron nitride current drop prevention technology of the present invention chemical reaction aborning adjusts accordingly, avoid the stage of power down stream, meet the heat-up time of normal synthesis needs, ensure the Quality and yield of product simultaneously, reduce the generation of useless block.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
A kind of Cubic boron nitride current drop prevention technology, comprises the following steps:
1), power bust 0.2-0.5KW will be synthesized in cubic boron nitride building-up reactions the fiercest period (holding stage);
2), treat the chemical reaction that cubic boron nitride building-up reactions is the fiercest after, synthesis power, after 30 seconds, is heightened 0.8-12.KW by smooth running,
3), whole process synthesis final pressure is not done and is changed.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, the technology distortion that every technical scheme according to the present invention is made, and all falls within protection scope of the present invention.
