氧化铝积聚(① In addition, poor SEN alignment and alumina buildup on the tip may cause the SEN to contact the steel shell, and this in turn can rupture the shell and result in a breakout 此外,浸人式水口对中不良、 Al₂O₃ 在其端部积聚都可能引起浸人式水口与钢质铸坯壳搭接,从而使坯壳破裂,导致漏钢。② Clogging in SEN due to alumina buildup leads to a large number of aborted sequences. Al₂O₃ 积聚造成的浸人式水口堵塞导致了大量的连浇中断。)
Al₂O₃ 堵塞(Bethlehem Steel Corporation — Sparrows Point Plant has used porous argon nozzles to prevent alumina clogging since start-up of the slab casters in 1985. 伯利恒钢公司雀点厂自1985年板坯连铸机投产以来,为防止 Al₂O₃ 堵塞已使用了透气型吹氩水口。)
Al₂O₃ 沉积(The benefit achieved with the doloma nozzle is the reduction in argon usage while eliminating alumina deposition on the wall of tundish nozzle. 煅烧白云石水口的优点是降低了氩气用量,同时又避免了 Al₂O₃ 在中间包水口壁上沉积。)
