Introduction:

Vertical type Vacuum Gas Quenching Furnace is a precision heat treatment equipment integrating vacuum environment heating and high-pressure gas quenching. It is mainly suitable for vacuum gas quenching processes of large and easily deformable workpieces such as round parts, long rod parts, shaft parts, and plate parts. Its working principle is to heat-treat metal materials in a vacuum environment, then rapidly cool the materials by injecting inert gases (usually nitrogen or argon). The vacuum environment can effectively prevent oxidation on the material surface, while rapid cooling helps form a uniform organizational structure, thereby improving the material’s strength, hardness, wear resistance, and corrosion resistance. It is widely used in industries such as aerospace, automobile manufacturing, and ring mold manufacturing.

Main Advantage

1.Prevention of Oxidation and Decarburization: Heating and quenching are performed in a high-vacuum environment, which effectively isolates external air, preventing workpieces from oxidation and decarburization during heating and cooling processes. This ensures the surface finish and inherent performance of the workpieces are maintained.

2.Precise Temperature Control: The advanced temperature control system can limit temperature fluctuations within ±5℃, ensuring uniform temperature distribution across the workpiece during heating and heat preservation stages, thus guaranteeing consistent heat treatment quality.

3.Fast Cooling Speed: Through the combination of high-pressure inert gas and high-speed fans, rapid cooling of workpieces can be achieved in a short time. The efficient cooling performance helps reduce internal thermal stress of workpieces and unevenness in microstructural transformation, improving the mechanical properties and stability of the workpieces.

4.Minimal Workpiece Deformation: Precise temperature control and uniform cooling methods keep the deformation of workpieces within a small range during quenching. This helps maintain the shape accuracy and dimensional stability of workpieces, meeting the requirements of high-precision processing and assembly.

5.Energy Efficiency and Environmental Friendliness: Compared with traditional heat treatment equipment, vacuum gas quenching furnaces operate in a vacuum environment, reducing energy waste and minimizing environmental pollution.

1.Heating Chamber

Heating Chamber：Circular

Heating Element：Graphite / Molybdneum

The heating chamber consists of a stainless steel frame, heat insulation layer, heating elements, insulation parts, and a furnace bed. According to customer requirements, heating elements are made of different materials for various scenarios, with a maximum operating temperature of up to 1300℃ and excellent furnace temperature uniformity.

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.
