Introduction：
The double-chamber vacuum oil quenching furnace is a vacuum heat treatment equipment with separate spatial layouts for the cold chamber and hot chamber. In a vacuum environment, workpieces are heated in the hot chamber and quenched in the cold chamber.Workpieces are fed into the cold chamber by an external charging cart. After closing the furnace door, the automatic operation program is activated, and the conveying system transfers the workpieces into the hot chamber for heating. Once the rated temperature is reached, the workpieces are returned to the cold chamber. Subsequently, they are lowered into the oil chamber located below the cold chamber for oil quenching. After completion, the workpieces are lifted back to the upper cold chamber, thus finishing the entire oil quenching process.
Main Advantage
1.The separate design of the two chambers reduces the probability of quenching oil vapor entering the heating chamber, maintains the temperature of the hot chamber to enable continuous heating and quenching operations, and lowers energy consumption by 30-35%. It also reduces the risk of corrosion of heating elements by oil vapor and minimizes fire hazards.
2.The spatial layout of the two chambers further reduces the risk of heating elements being corroded by oil vapor and lowers potential fire hazards.
3.The vacuum environment effectively minimizes oxidation and decarburization of workpieces, ensuring excellent surface quality.
4.Uniform heating and stable processes significantly reduce the risk of workpiece deformation and cracking, making it particularly suitable for processing precision parts.
Related Configuration
1.Heating Chamber
Heating Chamber：Circular
Heating Element：Graphite
Heating chamber is composed of a stainless steel frame, heat insulation layer, heating elements, insulation components, and a furnace bed. The graphite heating elements exhibit excellent high-temperature resistance, with a maximum operating temperature of up to 2400℃. The furnace temperature uniformity is excellent, and the insulation layer is sufficiently thick, ensuring good heat retention performance.
2.Vacuum system
Well-known domestic and foreign vacuum pump brands, such as EVP, Leybold, etc., are matched according to customer needs.
3.Control system
The operation control of this equipment is performed by the Siemens S7-1200 programmable logic controller. Interlock protection control is adopted for the equipment’s vacuum pump, valves, heating power supply, cooling fan, and other components. The system can judge and alarm abnormalities occurring during equipment operation, enabling fully automatic control. The network system supports remote network control and data transmission functions. All low-voltage components use international brands such as Siemens, Schneider, and Phoenix, which are highly reliable in terms of quality, performance, and craftsmanship, reducing the failure rate of the control system.
●The network system supports remote network control and data transmission functions.
●Remote fault diagnosis, remote process debugging, etc.
●Supports software upgrade and update.
4.Other System
Our temperature measurement system adopts a nine-point temperature measurement method to monitor product temperatures in real-time and accurately, ensuring the uniformity of furnace temperature is maintained within the range of ±3℃ – ±5℃; the pneumatic system supports automated control via a touchscreen, enabling pneumatic control of the entire gas circuit; the inflation system can be set up once with no need for further adjustments, as on-off control is achieved through solenoid valves, making it simple, convenient, and easy to adjust; an independent water cooling system is equipped, mainly used to control the temperature of the furnace body, vacuum pump, and heating electrodes to maintain the normal operation of the vacuum furnace.
We have an independent after-sales service department that provides users with timely services and guarantees a 24-hour rapid response.
