About High Alumina Sillimanite Refractory Products
FLONITE-70 High Alumina Sillimanite Refractory
FLONITE-70 is a premium-grade high alumina sillimanite-based refractory engineered for demanding high-temperature industrial applications up to 1500 degrees Celsius. Manufactured from carefully selected high-purity sillimanite minerals and optimized alumino-silicate compositions, FLONITE-70 develops a stable mullite-rich microstructure during service, providing exceptional thermal and mechanical performance.
The brick exhibits excellent refractoriness, high hot strength, superior resistance to thermal shock, and outstanding dimensional stability at elevated temperatures. Its low creep characteristics and resistance to chemical attack make it suitable for severe operating environments involving rapid temperature fluctuations, abrasive conditions, and corrosive atmospheres.
FLONITE-70 offers reliable performance in furnaces, kilns, reheating units, glass melting equipment, steel processing installations, and other thermal processing systems where long service life and operational stability are critical. The combination of high alumina content and sillimanite-derived mullite formation ensures enhanced resistance to spalling, slag attack, and flame impingement, resulting in reduced maintenance requirements and improved furnace efficiency.
