Behavior of Zr02-C Refractories in Thin-strip Casting of Steel
Abstract
Zirconia graphite refractory is used as a core-nozzle in the thin-strip casting of steel. Post-mortem analysis of used refractory was performed in an effort to establish the failure mechanism Corrosion behavior was studied Iagainst molten steel with MnO - Si02 based liquid inclu-j sions. Corrosion of these materials involves dissolution and oxidation of graphite in the matrix, folloived by pene- Tration of liquid slag leading to degradation of ZrO2 particles. Thermodynamic equilibrium calculations were, performed to study this corrosion mechanism.
