Abstract

The corrosion behaviour of MgO-C refractories by high manganese steel melt was investigated. The results demonstrated that corrosion mechanism of MgO-C refractories by manganese steel with a manganese content of less than 20 % is mainly decarburization reaction, while the corrosion for manganese content of 30 % is mainly reduction reaction of MgO by C and [Mn] as well as the penetration of Fe-Mn-Si melt, and the number of the MgO-rich inclusions significantly increase. The aluminium addition promotes the decarburization reaction, and the [Al] react with MgO directly to form Al₂O₃, follow by MgO·Al₂O₃ was generated at around the periclase in MgO-C refractories, and the inclusions mainly transform from TiN-AlN to TiN-MgO-AlN with MgO core.

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.
