Production process of diamond catalyst

Abstract

The invention relates to a production process of a diamond catalyst, which is characterized in that the procedures of the production process comprise proportioning, vacuum smelting, ingot casting, hot forging, hot rolling, butting winding through argon arc welding, mechanical cleaning, cold rolling, punching, surface processing, sorting and packaging. Compared with the traditional production process of the catalyst, the production process has the advantages that the production processes of the hot forging and the cold rolling through continuous winding are added; the surfacing and the annealing are canceled; the grain structure of the catalyst is changed; and the synthesis range of the catalyst is added. When the synthetic diamond catalyst is used for synthesizing diamonds, the production process has the advantages of wide synthesis pressure, wide synthesis temperature range and the like, the yield per unit of diamonds is high, and the synthesis course is easy to control; and the synthetic artificial diamond has the advantages of good color, good crystalline form, less internal defect, high strength and good thermal stability. Furthermore, the production process has the advantages that the finished product ratio of the catalyst is enhanced; the raw materials are saved; the production efficiency is enhanced; the production efficiency is reduced; and the production cost is reduced.

Description

technical field [0001] The invention relates to a new production process for synthesizing artificial diamond with contact coal, which is a significant improvement on the contact coal production process. technical background [0002] The synthesis of synthetic diamond usually uses coal as a catalyst to reduce the synthesis temperature and pressure. The traditional production process of coal contact for synthetic synthetic diamond is: [0003] Ingredients→Stamping→Polishing→Sorting→Packaging. [0004] In the traditional production process, coal contact inevitably brings defects such as pores, porosity, composition segregation, and coarse crystals caused by casting, which seriously affects its catalytic performance in the process of synthesizing synthetic diamonds and the quality of diamond products. In addition, co-planing The surface process removes the dense layer on the surface of the ingot, which affects the yield of the catalyst; the shearing process is time-consuming a...
