摘　　要：介绍了天津钢铁集团有限公司120t顶底复吹转炉底吹透气元件的维护方法。分析出底吹透气元件失效的主要原因是透气砖堵塞、透气元件侵蚀。通过采取有效的措施,采用初期形成炉渣-金属蘑菇头、中后期控制炉底波动的手段,使整个炉役过程中复吹效果良好。The maintenance method for porous plug for TISCO 120 t Top & Bottom Blowing Converter is introduced.Analysis shows the main reasons of its failure are plug clogging and erosion.Effective measures were taken so that a metal mushroom of slag could form at early phase and bottom fluctuation was controlled at intermediate and late phase,which gave good blowing effect during the entire campaign.
