| Abstract Scope |
Flexospheres is a recent product development successfully implemented in fired magnesia-chromite bricks. The technology focuses on the inhibition of the corrosion mechanism and a higher flexibility of the refractory product. The experimental investigation included chemical and physical analysis as well as dynamic corrosion wear experiments in a rotating high frequency induction furnace. According to the results, the technology does not only improve corrosion resistance but also contributes to the formation of a more flexible structure, which results in a better thermal shock stability. A field trial in the lower vessel of a RH degasser endorses the results observed in this investigation at laboratory scale revealing a clear performance increase. These extraordinary properties make the development suitable for special applications under aggressive conditions such as taphole areas, the tuyere area in copper furnaces or the RH degasser in the steel industry and guarantees a significant quality improvement of the magnesia-chromite product. |
