连铸中间包水口堵塞一直是困扰炼钢厂的一个难题,对于它的研究已经开展了30多年,然而该课题仍没有很好地解决。堵塞是由钢水中的固态微小夹杂物(尤其是Al2O3、TiO2和CaS)沉积引起。浇铸时,Al2O3等非金属夹杂在浸入式水口壁上逐渐形成,周期性地剥落带入结晶器,使铸坯中有害的大型夹杂物增加。此外,水口堵塞导致浇铸提前结束,以致连浇炉数减少和降低连铸机搜狗彩票的生产率。尽管通过向塞棒、中间包水口和套管吹氩可以减少堵塞,但分散的非金属夹杂和弯月面处的扰动仍会增加连铸板坯的大型夹杂物的数量,因此影响产品的表面质量。

水口侵蚀只是造成水口堵塞的一个必要条件。观察大量的废弃水口,都有不同程度的侵蚀,但其中一部分水口的粘附层很薄,甚至没有粘附层。这说明即使水口发生侵蚀,但只要钢水中氧化夹杂物,特别是氧化铝夹杂少,水口堵塞几率就能大大降低。因此,尽量降低钢水氧化性夹杂,并做好防止钢水二次氧化工作,是降低水口结瘤率的关键。堵塞的水口由基体、中间反应层、表面沉积层三部分组成。
