Mullite castable is a kind of high quality mullite refractory castables, which is mainly made of high quality porous mullite aggregate as raw material, mixed with fine powder and additives. The critical particle size of this series of refractories is 12mm, and the long-term service temperature is 1350℃.
Mullite refractory castables is made of mullite aggregate and powder and some binder. With high mechanical strength and good resistance to thermal shock and abrasion, it is mainly used as the lining of boilers, blast furnace hot blast furnaces, heating furnaces, ceramic kilns and other kilns.
This series of refractory castable can be used as working lining with high temperature and direct contact with flame, realizing high temperature and energy saving. Its unit unit weight is light, the structural weight reduces 40 ~ 60%, eliminates the furnace top hanging brick broken brick hidden danger. Its thermal conductivity is low, with porous mullite aggregate batching, thermal conductivity is low, thermal insulation performance is good, can quickly drying furnace, shorten drying furnace period, significant economic benefits.
Mullite refractory castables is mostly used in petrochemical industry tubular heating furnace, light diesel oil, ethane cracking furnace lining, atmospheric and vacuum furnace, sulfur recovery device, steam boiler, cuticle net thermal insulation layer, two cylinder and pipe thermal insulation monolayer, other industrial furnace door, fire hole, observation hole door lining and so on.
