摘要：
During the pouring process, there is an electric field at the multiphase interface between the refractory material, slag, and molten steel, which promotes the nodulation and erosion of the submerged entry nozzle (SEN). During the casting process of cold head steel, industrial tests were carried out on the grounding of the nozzle. The results show that the grounding of the nozzle has a significant inhibitory effect on the formation of clogging products and the adhesion of slag on the SEN surface, so that the erosion effect of clogging products on the SEN is weakened. At the same time, the reduction of clogging products on the nozzle can stabilize the flow of molten steel, which is beneficial to the reduction of inclusions in the slab. The adverse effects of unsteady casting can be effectively suppressed by controlling the electric field characteristics of the interface between the nozzle and the molten steel.
