| met. | 陶瓷保护套管 | ceramic shroud (Unfortunately, the presence of a ceramic shroud does not ensure the elimination of reoxidation. It can be very difficult to seal the joint between the ladle nozzle and ceramic shroud, as we have just discussed. 遗憾的是,有了陶瓷长水口也不能保证不发生二次氧化。正如我们刚刚讨论过的那样，对钢包水口和陶瓷长水口结合处进行密封可能十分困难。) |
