摘　　要：延迟石油焦是预焙阳极生产的主要原料之一,其质量控制不仅对预焙阳极理化性能指标的改善至关重要,而且也直接影响其采购成本。因此,通过合理选择延迟石油焦供应商并控制供应商数量,逐步建立延迟石油焦信息数据库,采用延迟石油焦分类堆放及选择合理混配工艺等控制方法,一方面能够控制石油焦挥发分含量水平,为煅烧工序的正常运行及煅烧焦质量提供基本保障,另一方面能够在控制延迟石油焦采购成本的基础上,有效控制影响预焙阳极CO2、空气反应性残余指标的微量元素Na、Ca、V、Ni含量。The delayed petroleum coke is one of mainly raw material for prebaked anode. Its quality control is not only very crucial for anode property,but also indirectly influence the cost of delayed petroleum coke. Therefore, the control measurements by reasonably choosing delayed petroleum coke suppliers and controlling its quantity, gradually setting up database for coke information,adopting the classified stacking and blending for coke were implemented. On one hand,it could control the volatile matter content of blended coke and guarantee stability for coke calcining process; on the other hands, it could effectively control the trace content of Na,Ca,V,Ni of blending coke which affect the CO2 and air reactivity residue of prebaked anode.
