The End Of Fused-Cast Refractories In Soda-Lime Glass Furnace Superstructures?

Fused-cast refractories (FCR) applications have been extended beyond the use within fusion, refiner, distributor and channels sections of smelters. Traditional bricks have been replaced in the superstructure and, after the advent of oxy-fuel technology, have proved to be technical solutions for the crown (Alumina and AZS), where the replacement of traditional silica is only hampered by financial costs. Fused-cast refractories are the most successful refractories to be installed in glass melting tanks. This article highlights how their application has contributed to the evolution of glass.
