It is demonstrated that the degradation of materials is currently a poorly studied scientific area. We propose a definition of degradation and a classification of the types of degradation. It is investigated, using a technical model, the destructive interactions between the ceramic materials of the tundish refractory lining, in a continuous steel casting plant. We hereby present the experimental results regarding: - the importance of the steel penetration depth in the refractory ceramic mass; - the assessment of mineralogical degradation; - the analysis of chemical degradation. It is shown that the results of laboratory - pilot scale research can be extended to the industrial level.
