Product Description
The honeycomb ceramic as heat exchange media is the key part for heat storage HTAC(High Temperature Air Combustion) technology, which 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 and all kinds of ceramic cellar stove, glass cellar stove in building materials, and all kinds of tap heating stove, splitting stove, other industrial stove cellar, too.
Honeycomb ceramics as heat storage body, by the advantage of large specific surface area, small heat resistance, good thermal conductivity, excellent thermal shock resistance, realize quickly exchanging heat; Reducing energy in the strict sense (up to 97% of true thermal energy can be recovery and also it can absorb NOx more than 40%).
The corundum/mullite and cordierite/mullite complex thermal storage honeycomb ceramic developed by our company has the following notable characters: Perfect high temperature resistance, anticorrosion, perfect thermal shock stability, high mechanical strength, large thermal storage capacity, advantaging heat conduction property, energy conserving result and service life are improved greatly. At present, our products have already been approved by numerous iron and steel enterprise and exported to Japan, South Korea and Europe and America market.
