摘要：

The clogging behavior of a new ZrO2-C submerged entry nozzle (SEN) in the industrial production of ultra-low carbon steel was studied. The results revealed that, compared to the Al2O3-C SEN, the clogging thickness at the ZrO2-C SEN outlet was reduced by over 20 % to the formation of a dense protective layer composed of CaOAl2O3-SiO2 at the interface near the molten steel. Additionally, the corrosion layer formed within the ZrO2-C SEN effectively prevented decarburization and diffusion of CO. The use of the ZrO2-C SEN improved the qualification rate of the liquid level fluctuation and the defect rate of the slab was reduced by approximately 17 %. The related reactions occurring inside the nozzle were simulated and compared with the experimental results in detail.
