Abstract
Fused cast refractory moldings having a random microstructure, which are near in size and configuration to the desired final shape, and process and apparatus used in their manufacture are described. The process includes rapid melting of the refractory material followed by controlled rapid cooling. Laminated composite fused cast refractories may be produced.
Claims2
A refractory fusion cast molding of alumina-zirconia-silica composition characterized in its as-cast form by the absence of a header and having throughout a generally random, uniform microstructure, generally evenly distributed closed pores and generally uniform chemistry.
