在我国铸锭盛钢桶自使用滑动水口实验成功以来,由于其所具有的一系列优点,因而得到迅速的推广。尽管如此,滑动水口的使用也还存在一些问题需要解决;例如,在需要降低注速而节流的情况下,钢流发散和钢流的不稳定(摇摆)使上注时钢锭表面不良、镇静钢的 In our country since the successful use of ingot Shengduanshuizu experiment, due to its a series of advantages, which has been rapidly promoted. In spite of this, there are still some problems to be solved in the use of the sliding nozzle; for example, the steel flow diverges and the steel flow instability (sway) when the injection speed needs to be reduced and the steel flow is unstable (sway) Steel
