Induction furnace test revealed that the magnesia chromite brick samples had no obvious corrosion in the slag zone. However, there was heavy erosion within the steel bath, mainly caused by the vigorous induction stirring (as shown in Fig.5). Periodical analysis of the slag chemistry showed that as the test progressing, the FeO level dropped from about 70% to less than 60%, which suggests that slag enriched with FeO might have been dragged by the induction stirring and reacted with magnesia chromite samples. Although sample no.2 had slightly higher HMOR strength than other two products, the sample exhibited significantly more localised erosion during induction furnace tests |
