Clogging behavior has been investigated by applying a direct current on a submerged entry nozzle (SEN). The relevant experimental results verify that the high-speed friction acting on the SEN not only leads to charging of the inclusions, but also inhibits the clogging behavior and improves the quality of the steel. After DC treatment, the formation of clogging in the SEN decelerates and the stability improves, such that the density of clogging increases and the porosity of clogging decreases significantly. Meanwhile, after applying a DC electric field, the overall quality of steel is also improved.

外加电场对铝镇静钢铸造过程中浸入式喷嘴堵塞行为的影响

通过在浸入式喷嘴 (SEN) 上施加直流电来研究堵塞行为。相关实验结果证实，作用在SEN上的高速摩擦不仅导致夹杂物带电，而且抑制了堵塞行为，提高了钢的质量。DC处理后，SEN内堵塞的形成速度减慢，稳定性提高，堵塞密度增加，堵塞孔隙率显着降低。同时，施加直流电场后，钢材的整体质量也有所提高。
