Carburizing quencing Furnace=410KW,Tempering Furnace=250KW.
2) The Length of the whole equipment is about 66 meters
3) Total weight: about 78 tons
4) Facilities Parameter: three-phase current, input power voltage of 415V±5% and
50Hz frequency. 220-250V 50Hz frequency
5) Carburizing quenching Furnace 820ºC---920ºC, Quenching cooling oil Tank 60-80ºC, Tempering Furnace 300ºC---650ºC,Dephosphating tank 70-90ºC,degreasing & washing tank 60-80ºC
4.2 Front degreasing &washing tank
This device is open structure. The work pieces soak in the hot water to clean the oil and impurities. It is composed with the degreasing tank, driving system, spray system, oil-water separator skimmer, filter unit etc.
4.3.Degreasing tank
This device is open structure. This device is composed with Dephosphating tank,
transmitting belts, reduction gear, chain, chain wheel, transducer. The dimensions of
tank can be choosed by capacity of treating work pieces. The heating device,
transmitting belts, chains are adopts SUS304 stainless steel. The work pieces
which in the feeding machine drop into the dephosphating tank equably to wipe out
the oxide of work pieces 's surface ,by this the surface of work pieces are smmoth. Then work
pieces are send to washing machine by transmitting belts for cleaning the raffinate.
4.4. Front degreasing & washing tank with drying
This device is open structure. The work pieces soak in the hot water to clean the oil and impurities. It is composed with the degreasing tank, driving system, spray system, oil-water separator skimmer, filter unit etc.
4.5. Continuous bright carburizing quenching furnace(main furnace)
This kind of carburizing Furnace is the main device of the production line, it is mainly composed of furnace cover, mesh belt conveyor system, roller transmission, heat preservation material, heating elements, furnace fan circulating device, gas cracking control device, work pieces dropping device and temperature control device.
4.9. Tempering furnace
The tempering furnace is composted of cover, feeding shelf, wire mesh belt driving
device, material of hot insulation, heating apparatus, circulating fan apparatus,
discharging rack, and Temperature control apparatus. There are 5 high speed
mixing fans on top of furnace, which can make the convection current to ensure the
temperature uniformity inside the furnace, small hardness balance of work pieces and
color uniformity after tempering.
In order to avoid the large temperature drop, We make the power density of first zone
and second zone closely. The belt drive transmitting by Cycloidal Pin Gear Speed
Reducer.
4.10.Double dyeing tank with drying device
This device is double open structure. Tank capacity is about8M3,depth is 2.3m with
cooling & heating function. It can control cooling liquid temperature in set range
automatically, to assure bolts dyeing uniformly and drying. Then the work pieces
transmitting by belts to dry by drying device.
4.11.Double oiling machine
This device is composed with frame, immerse horizontal tank and transmitting belt. The spray system flame plating the oil on the work pieces , then it avoids the spare oil by strong blower, meanwhile saving the oil.
This is the specifications of 1 tons furnace.
