摘　　要：反应性是预焙阳极的重要质量指标,改善阳极的反应性既可以降低阳极的过量消耗,又可以减轻阳极“掉渣”对槽温、电流效率等方面的影响。通过理论分析,结合生产实际,采取加强残极清理、残极收尘粉外排和优化石油焦混配等措施,改善了预焙阳极反应性。Reactivity is an important quality index of prebaked anode.Improving the reactivity of anode can not only reduce the excessive consumption of anode,but also reduce the influence of anode"slag"on bath temperature and current efficiency.Through theoretical analysis and production practice,measures such as strengthening residual electrode cleaning,discharging dust powder from residual electrode and optimizing mixing of petroleum coke were adopted to improve the reactivity of prebaked anode.
