In this study, main aspects found in the literature about refractories corrosion were reviewed, evaluating the feasibility of certain tests and relating them with experimental results. The main cause of refractories wear is considered the chemical attack that the material suffers, but it is also influenced by thermal and mechanical factors, often concomitantly. Increased life of refractories faces the understanding of complex phenomena and depends on operational factors, whose control is difficult in routine steel company processing. In addition the physical and chemical properties of refractories must be considered. In the proposed approach, research data of corrosive wear of basic refractories, including microstructural analysis, are related to the theoretical fundamentals found in literature.
