Heat treatment furnace RJ3 series

annealingpitgas

Application：forging parts, casted parts,pressure vessel,Train railway,special steel plate,shaft,rotary parts,centrifugal fan impeller Pit annealing furnace is widely applied in the annealing heat treatment process. Structures:It consists of furnace shell,furnace lining,heating element,furnace cover,furnace door lifting device,intelligent electronic control system and son on. 2. Features 1).If it is damaged by mechanical collision, it only needs local modification, repairing, replacement, and can be put into application after repaired without heating the empty furnace. 2).The refractory fiber is ceramic fiber block, with good heat preservation effect, fast temperature rising, it can save energy by 20% - 30% compared with brick lining. 3).The service life is long 4).Adopt circulation fan within the furnace to stir the air in the furnace, to strengthen the internal gas flow, effectively increase the furnace temperature uniformity. 5).Seismic resistance performance is good. 6).Good temperature controllability, temperature control precision can be up to ±10 ℃ 7).Furnace internal temperature partition piecewise control can be realized. 8).Good corrosion resistance, especially effective for sulfur-containing atmosphere and those that is polluted by sulfur-containing substance.
