The study of submerged entry nozzle clogging dynamics mainly focuses on the interface wetting behavior. So as to understand the effect of the interface electric field on the wetting behavior between the immersion nozzle and the molten steel, electrowetting experiments and field industrial tests were performed. The results show that the wettability between the iron droplet and the nozzle constituent material can be improved by applying an electric field, and the solid–liquid wetting angle decreases with increasing voltage. There is an electric field at the interface between the submerged entry nozzle and molten steel during continuous casting, and the resulting electrowetting effect significantly changes the wetting behavior between the molten steel and the nozzle, which promotes the interaction between the two phases resulting in a large amount of deposits on the inner surface of the submerged entry nozzle, causing nozzle clogging.

界面电场对铁水与浸入式喷嘴界面润湿性的影响

浸入式喷嘴堵塞动力学的研究主要集中在界面润湿行为上。为了了解界面电场对浸入式水口与钢水之间润湿行为的影响，进行了电润湿实验和现场工业试验。结果表明，施加电场可以提高铁滴与喷嘴构成材料之间的润湿性，固液润湿角随着电压的增加而减小。连铸时浸入式水口与钢水界面处存在电场，由此产生的电润湿效应显着改变钢水与水口之间的润湿行为，
