Electrofused AZS refractories for high-capacity glass-founding furnaces

Abstract

This article describes the parameters for the efficient operation of modern glass-founding furnaces designed to produce commercial glass. It also describes the structure of the heat-insulating and refractory materials used to line such furnaces. Requirements are formulated for the quality of electrofused alumina-zirconia-silica (AZS) refractories used in high capacity glass-founding furnaces. An efficient scheme is proposed for using AZS refractories to line the hot zone of a glass-founding furnace with a capacity of 280 tons/day. © 2013 Springer Science+Business Media New York.
