Abstract
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 CaO-Al2O3-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.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
