Honeycomb Ceramic for RTO, RCO

Introduction:
The honeycomb ceramic is the key part for heat storage HTAC (High Temperature Air Combustion) technology. There are a variety of materials for honeycomb ceramic, such as cordierite, activated carbon and alumina as well as fused silica. The honeycomb ceramic enjoys excellent heat capacity, thermal shock and chemical resistance.

Application:
The honeycomb ceramic for RTO, RCO has been widely applied in all kinds of pushing-steel heating furnace, RTO(regenerative thermal oxidation), stepping heating furnace, heat treatment furnace, forging furnace, dissolving furnace, steel wrapping/middle wrapping baking apparatus, soaking pit, radiation tap incendiary apparatus, covering furnace, high temperature hot-blast stove in metallurgical machine building. It can also be used in all kinds of ceramic cellar stove, glass cellar stove, tap heating stove, splitting stove and other industrial stove cellar.
