利用复合粉末介质火抛水钻珠坯的方法
摘要：
本发明公开了利用复合粉末介质火抛水钻珠坯的方法，属于水钻珠坯加工技术领域，将复合介质粉末和水钻珠坯混合均匀后加入到旋转的金属圆筒中，加热火抛；其中，复合粉末介质包括石墨粉末和无机粉末，石墨粉末、无机粉末和水钻珠坯的重量比为（1‑4）：（1‑6）：（93‑96）。本发明的利用复合粉末介质火抛水钻珠坯的方法能够提高水钻珠坯火抛的圆度和效率，缩短水抛圆修整时间，提高火抛炉工效，同时，复合粉末介质可循环使用，减少石墨粉氧化消耗，改善生产环境，还能使抛圆后的水钻珠坯易清洗。
摘要（英）：

The invention discloses a method for fire polishing of a rhinestone pearl blank by means of a composite powder medium, and belongs to the technical field of rhinestone pearl blank machining. The method comprises the step that the composite powder medium and the rhinestone pearl blank are added into a rotary metal cylinder after being evenly mixed and are heated and subjected to fire polishing, wherein the composite powder medium comprises graphite powder and inorganic powder, and the weight ratio of the graphite powder to the inorganic powder to the rhinestone pearl blank is (1-4):(1-6):(93-96). According to the method for fiber polishing of the rhinestone pearl blank by means of the composite powder medium, the fire polishing circular degree and efficiency of the rhinestone pearl blank can be improved, the rhinestone spheroidizing and finishing time can be shortened, the working efficiency of a fire polishing furnace can be improved, meanwhile, the composite powder medium can be recycled, graphite powder oxidation consumption can be reduced, the production environment can be improved, and the spheroidized rhinestone pearl blank can be easy to clean.
