摘　　要：通摘要本文介绍了微量元素对顸焙阳极质量的影响，指出应加强石油焦和残极中微量元素的控制，残极添加量控制以不超过10-15％为宜；罐式炉应以挥发分为主，参考V、S进行均配生产；提高焙烧排烟架温度，有利于提高产品质量。This paper describes the inflence of the trace elements on the quality of the pre-baked anodes, andthe trace elements in petroleum coke should be controlled, as far as the anode butts, 10-15% is suitable.Differentvarieties of petroleum coke should be mixed mainly according to the volatile content when Tank Calciner is used,andthe Vanadium and Sulfur is the secondary consideration. Raising the highest tempreture of the Exhast Rack isbeneficial to the anode quality.
