Thermal Ceramics Pyro-Bloc ZR
Categories:	Ceramic
Material Notes:	Pyro-Bloc Veneering modules, R Grade, ZR Grade, C Grade are made Pyro-Log fiber turned edge-grain and slightly compressed with a gauze type wrap. Pyro-Bloc Veneering Modules are part of the Unisystem family of products. They can be applied over a variety of refractory surfaces using K-Bond mortar. Unikote M or S surface coatings are normally applied over the module hot face to provide thermal stability and chemical attack resistance. Features: 12" x 12" (305 mm x 305 mm) blocks of ceramic fiber insulation Easily installed over existing refractory surface Improves furnace efficiency without replacing a serviceable refractory lining Monolithic, edge-grained ceramic fiber modules Maximum temperature rating 2600°F (1427°C) Applications: Forge furnaces Crucible furnace Rotary hearth furnace Holding furnace Heat treating furnace Pusher reheat furnace Ceramic kiln Information provided by Thermal Ceramics Data has not been recently verified.
