Summary

Fusion-cast alpha-beta (αβ) as well as beta (β) alumina refractory crowns have now been in service in oxy-fuel furnaces for several years. In North America, αβ-alumina refractory has been used for oxy-fuel furnace crowns in specialty, float, and container glass furnaces. This paper will highlight the practical experience gained with successful installation, start-up, and operation of fused alumina crowns under a wide range of glass melting conditions. The costs versus benefits of fused αβ-alumina crowns will also be discussed.
