Vacuum Gas Quenching Furnace
Vacuum high-pressure gas quenching furnaces are primarily used for vacuum bright quenching, sintering, and brazing of tool steel, die steel, elastic alloys, stainless steel, and 3D printing additive materials. They primarily consist of a pressure furnace body, heating chamber, vacuum system, electronic control system, gas charging system, water cooling system, pneumatic system, and a transport vehicle.

Structural features of
Vacuum Gas Quenching Furnace
Starting from the internal structure, we show you the unique design logic of vacuum gas quenching furnace products:
-
Chamber and heating
The heating chamber consists of graphite heating body, graphite soft felt and hard felt.
The heat field can also be heated by high-temperature molybdenum strips and the chamber can be heated by molybdenum foil heat insulation screens, which are free of volatilization, impurities and pollution.
-
Air cooling system
The rear part of the chamber body consists of a high-pressure impeller converter, a multi-stage copper heat exchanger and a high-efficiency air duct guide device. During air cooling, high-purity nitrogen or argon is introduced. Driven by the high-speed impeller blower, the gas is drawn into the impeller through the high-efficiency copper heat exchanger. After being deflected by the impeller, it is sprayed from the graphite nozzle toward the workpiece through the air duct guide device, ensuring uniform forced cooling of the workpiece.
-
Appearance design
The material table is composed of graphite pillars, graphite hearth, and Al2O3 spacers on the hearth. This structure can prevent the material tray and graphite hearth from sticking together at high temperatures.
-
Control system
PLC automatic control system, the human-machine interface adopts high-definition touch screen, and has a built-in operating system developed by us.Programmable temperature control instrument PID adjustment.

FAQ
Focus on answering common questions to provide users with clear and practical usage guidelines:
-
Q:Can the gas cooling rate of the vacuum gas quenching furnace be adjusted?
A:The gas cooling pressure is adjustable from 1 to 10 bar. By controlling the inert gas (high-purity nitrogen/high-purity argon) injection pressure and fan speed, the cooling requirements of different materials can be met.
-
Q:Will the workpiece surface oxidize or discolor after gas quenching?
A:No, the vacuum environment isolates the air, and the inert gas is non-oxidizing. The workpiece surface is bright after quenching, eliminating the need for subsequent cleaning steps such as pickling.
-
Q:What is the maximum workpiece weight that can be processed?
A:Different vacuum gas quenching product models have different working dimensions and loading capacities. We offer a variety of models with loading capacities ranging from 100kg to 900kg. You can choose the model based on workpiece size and production capacity requirements.
