. Our products have developed from polycrystalline mullite fiber wool to the current Nengcheng lightweight refractory series that can adapt to high, medium and low temperatures. The main products include polycrystalline mullite fiber, polycrystalline alumina fiber, aluminum silicate fiber, high aluminum fiber, zirconium-containing fiber and various fiber products; composite fiber prefabricated blocks; all-fiber furnace box-type resistance furnace; high-temperature adhesives, etc.
A process engineer sizing the lining for a 1300 °C debinding and sintering furnace usually ends up with three quotes on the desk: dense fireclay brick at the lowest unit price, 0.8 g/cm³ insulating firebrick in the middle, and a 128 kg/m³ ceramic fiber module system at the top. ...
A furnace lining rarely fails because the brick was "not high alumina enough". It fails because the grade was picked from a label instead of a data sheet. We regularly see 1,400 °C heat-treatment furnaces lined with a 55% alumina brick that spalls within a year, while a nearby 1...
