Investigation of Microstructure and Phase Composition of Chromic Oxide, AZS/Cr and High-alumina Refractories after Exposure of Basalt and Aluminaboronsilicate Glasses Melts.

The microstructure and phase composition of high-alumina, chromic oxide, and AZS/Cr refractories containing 30% and 60% (by mass) Cr2O3 after exposure to aluminaboronsilicate glasses and basalt melts depending on the type of melts and temperature have been studied. The mechanisms of refractory corrosion by the used melts and the factors contributing to the inhibition of corrosion development have been investigated by the method of petrographic analysis. On the basis of obtained results, the use of high-alumina, chromic oxide, and AZS/Cr refractories in the sections of glass furnace linings, experiencing the intensive impact of aluminaboronsilicate glasses and basalt melts, has been confirmed and scientifically substantiated.
