Ceramic fiber lining
Petrochemical industry atmosphere furnace, vacuum furnace, ceramic fiber lining insulation is general designed to make the furnace wall temperature 80 ℃ (25 ℃ environment temperature and 0 ℃ wind speed). Atmospheric and vacuum furnace wall and furnace top heat insulation lining structure is 140 mm ceramic fiber blanket. The furnace bottom is lightweight refractory castable of 180 mm; because ceramic fiber product has good compression resilience, playing a big role in the lining seal, therefore the integrity of ceramic fiber lining sealing and heat preservation effect are good. Ceramic fiber lining makes atmospheric furnace heating furnace of vacuum furnace more efficiency in petrochemical industry.
