Abstract in another language

A thorough understanding of refractory lining corrosion processes in metallurgical reactors is crucial to improve lining lifetime and to decrease lining maintenance costs. Besides laboratory tests and plant trials, the modeling of corrosion processes provides an efficient and cost-effective tool to define the appropriate refractory material for a particular process slag composition. Thermochemical modeling was applied to: (1) study the interaction between covering slags of very distinct chemical composition with the tundish lining material, (2) understand the performance of repair mixes in contact with basic oxygen furnace (BOF) and electric arc furnace (EAF) slags, and (3) investigate the stable phases of infiltrated lining materials in a melting furnace with a process slag of very special chemical composition. The advantages and limitations of a phase equilibrium approach to examine corrosion processes in industrial metallurgy are discussed.
