| 摘 要： | 研究了利用硅酸铝质耐火材料废料制备高性能的绿色陶瓷研磨介质的技术及工艺条件对研磨介质耐磨性的影响.以硅酸铝质耐火材料废料为原料,以可溶性试剂和天然矿物为助熔剂均制备了耐磨性优良的含75%Al2O3瓷球研磨介质.发现用可溶性助熔剂制备的瓷球的耐磨性优于用天然矿物助熔剂制备的瓷球;延长废料的球磨时间,瓷球的烧成温度降低,晶粒尺寸减小,气孔变小而少,瓷球的耐磨性提高;增加坯体的成型压力,瓷球中的气孔减少,孔径变小,耐磨性提高.

| Abstract: | The technology of reusing aluminosilicate refractory waste to prepare high performance green ceramie ball milling media and the influence of prepared conditions on the wear rate of the milling media are studied in this paper. The alumina ceramic ball milling media with 75% Al2O3 and high wear resistance is prepared by usin aluminosilieate refractory waste as raw materials, and formulating with soluble or insoluble fluxes. The influence of the milling time of refractory waste and the shaping pressure of the ceramic body on the wear rate of the eeraminc ball milling meidia are studied. Results indicate that the wear rate of the ceramic ball which is prepared by soluble fluxes is higher than that of the ceramic balls which are prepared by insoluble fluxes, When the milling time of the refractory waste increased, the sintering temperature, crystal size, pore size and porosity of the ceramic ball decrease and th wear rate of the ceramic ball increase. When the shaping pressure of the ceramic body increases, the porosity and pore size of th eceramic ball decrease and the wear rate of the ceramic ball increases. |
