The present invention provides a silicon carbide ball production process, and relates to the technical field of silicon carbide balls, the silicon carbide ball production process comprises: 1, mixing quartz sand with coke, adding edible salt and wood dust, placing into an electric furnace, and heating to synthesize silicon carbide powder; 2, silicon carbide powder and carbon powder are used as raw materials, a sintering agent and a binder are added, and the mixture is stirred into slurry; 3, the slurry is introduced into a drying machine to be dried, then the slurry is poured into a ball forming machine, and blank balls are prepared; 4, the blank ball is put into a vacuum press, static pressing is conducted at the pressure of 140-160 Mpa, and a pressed blank body is obtained; before sintering, static pressure is carried out under the pressure of 140-160 Mpa, the pressure maintaining time and the pressure maintaining temperature are controlled, the high-density SiC green body is obtained, then sintering is carried out, the follow-up crystallization effect of silicon carbide is enhanced, the content of SiC in the prepared product is usually 99% or above, and the quality of the silicon carbide balls is improved.
本发明提供了一种碳化硅球制作工艺，涉及碳化硅球技术领域，包括以下步骤：步骤一：将石英砂与焦炭混合，加入食盐和木屑，置入电炉中，加热合成碳化硅粉；步骤二：以碳化硅粉和碳粉为原料，加入烧结剂和粘结剂，搅拌成浆料；步骤三：将浆料通入干燥机中进行干燥，然后将浆料浇筑入制球机中，制备出胚球；步骤四：将胚球放入真空压力机，采用140‑160Mpa的压力进行静压，获取压胚体；本发明在烧结前，采用140‑160Mpa的压力进行静压，控制保压时间和保压温度，得到高密度SiC坯体，然后再烧结，有利于增强后续碳化硅的结晶作用，使得制得的制品中SiC的含量通常在99％以上，提高碳化硅球的质量。
