Degradation of Ceramic Materials in Thermotechnical Plants
Keywords:
materials, degradation, continuous casting, ceramic - liquid steel interaction
Abstract
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.
