Pyroguard
Pyroguard is a precast refractory furnace shape made with a high alumina slurry and a high concentration of stainless steel fibers, usually a 304 or 310 alloy, although other wire alloys may be used. Multiple slurry formulations are also available including several alumina and silicon carbide compositions.
This material can survive repeated mechanical abuse, thermal cycling, compression and spalling conditions while maintaining its integrity. It is resistant to cracking or breaking in the most severe conditions. Pyroguard is often used to replace other refractories unable to withstand severe furnace conditions. It can be used as a replacement for cast iron, steel or water cooled sections in structural or support applications.
