Vacuum oil quenching vacuum furnace

Purpose: gear, shaft, bearing, chain, hydraulic parts, tools, standard parts stamping parts and other products of carburizing and carbonitriding, nitriding, carbon and nitrogen altogether permeability, vacuum bright quenching, light a fire, as well as the die steel, tool steel, bearing steel, stainless steel vacuum quenching process, etc
Advantages of vacuum oil quenching vacuum furnace:
It is heated in a vacuum to avoid oxidation of internal crystals and no plaque on the surface.
The vacuum carburizing workpiece is bright and silver-white.
Carburizing is uniform, without carbon black and sharp Angle hyperosmosis.
The carburizing effect of deep hole and blind hole is good.
No fire curtain door, no fire danger.
Convenient to stop the furnace, with the use, energy conservation and environmental protection.
The carburizing temperature is high and the carburizing time is shortened.
Cold furnace design, multiple combinations (single room, double room and multiple rooms)
Convenient and other equipment to form a production line.
Computer control, high degree of automation, reduce manual intervention.
The workpiece is evenly permeable.
Less energy consumption.
Very low carburizing media consumption.

1; High temperature uniformity and thermal efficiency.
2; Controlled heating process
3; Low temperature convection heating
4. Many zone temperature control
5; Multiple pulse process (negative pressure, positive and negative pressure)
6; The cooling process is controllable and the minimum quenching deformation is obtained.
7. Oil cooling closed cycle + stirring function.
8; Vacuum pressure
9. Touch screen display: precise and reliable operation control system.
10; All processes are free to program.
11. Fully automated equipment, perfect safety and abnormal alarm system.
12. Computer/computer group control system: set process programming, storage, report and so on.

Characteristics of negative pressure oil quenching vacuum furnace:
1. Full automatic program control, smooth operation, good reproducibility, and optional machine interface.
2. Using radiant tube heating, without carbon black insulation, the temperature rising and cooling rate is fast, and the thermal field is even, which is convenient for maintenance and replacement.
3. Multiple pulse processes (positive pressure, negative pressure, positive and negative pressure).
4. The heating chamber adopts the composite hard carbon felt and unique heating arrangement, without the occurrence of carbon black, and reduces the maintenance cost of the equipment.
5, carburizing nozzle 360 ° to decorate, overhead thermal cycle of flow fan, carburizing atmosphere.
6. The oil cooling system adopts the external circulation injection stirring device, the fast and flexible circulation, the sealing performance is good.
7. The internal and external materials are made of high quality steel plate, with large bearing capacity and no deformation at high temperature.
8. Economic and environmental protection, with very few media, no harmful gas emissions.
9. The carburizing time is 60% less than that of conventional furnace.
