| 摘 要： | 控制水口堵塞不仅有利于提高生产效率,而且有利于降低生产成本和改善钢材产品质量。通过在浸入式水口与塞棒间施加低密度脉冲电流,浇注实验后发现脉冲电流处理水口的内壁平滑,夹杂物附着程度明显低于无脉冲处理水口。因此,利用脉冲电流处理控制水口堵塞是一项提高水口使用寿命的有效方法。

| Abstract: | The prevention of the nozzles from clogging can not only improve the production efficiency,but al-so reduce manufacturing cost and improve the quality of steel. By the application of electric current pulses (ECP)between the stoppers and the nozzles during the continuous casting of molten steel,the blockage of nozzles reduced obviously and the inners of nozzles were smooth. Hence,the utilization of ECP treatment is an efficient method to increase the service life of nozzles. |
