摘　　要：中间包浸入式水口的堵塞是铝镇静钢连铸过程中普遍存在的问题,对于小方坯来说,问题尤为严重。包钢炼钢厂采用80 t转炉,钢包精炼炉(LF炉)和六流小方坯连铸机生产铝镇静钢。针对浸入式水口堵塞的问题,通过对LF炉精炼过程的优化,改善了钢水的浇铸性能,保证了小方坯铸机的顺利生产。Clogging of SEN （submerged nozzle） of tundish is a common problem during continuous casting of aluminum - killed steel, and the problem is especially serious when billets are produced. Steel - making Plant of Baotou Steel （Group） Corporation uses 80 t converters and LF and 6 - strand billet caster for production of aluminum - killed steel. Aiming at solving the problem of dogging of tundish SEN, the casting performance is improved to ensure smooth operation of billet caster through optimizing refining process of LF.
