Fired Refractory Shapes
Thermal Ceramics fired refractory shapes are used in a wide range of critical, heat intensive applications. High alumina, silicon carbide, fused silica and alumina-zirconia-silica (AZS) compositions are thixotropically cast to precise customer specifications. This process creates thermal-shock resistant refractory fired shapes which can be used in a wide range of critical, heat intensive applications.
The Cerox® line of refractory fired shapes are thixotropically cast using a dispersion agent, which allows the Cerox mix to flow when vibrated without requiring a high water content. These manufacturing techniques, combined with precisely controlled firing and 100% product inspection, produce high-quality components suited to the most arduous of high temperature environments. Cerox’s benefits include tight tolerance capabilities, good non-wetting characteristics, and excellent mechanical strength.
The Valcor® line of refractory fired shapes has a proven track record in molten glass contact applications and comes in a very smooth surface finish. Each fired shape is individually inspected to ensure it meets customer expectations.
