Abstract

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.
