The Vacuum Gas Quenching Furnace combines vacuum heating with high-pressure gas cooling for clean hardening, solution treatment and other qualified heat-treatment cycles.
It is selected for parts where material hardenability, section size, load density, surface condition and dimensional control must be considered together with gas pressure, circulation and heat-exchanger capacity.
Cooling rate, hardness and distortion are matched to the alloy, geometry, fixture, batch arrangement and validated recipe. SYNHTE can support representative process trials to confirm the selected cooling route and acceptance targets.
Our vacuum gas quenching furnaces are designed to perform precision heat treatment cycles under high-vacuum heating followed by high-pressure inert gas cooling.
Compared with oil quenching systems, gas quenching offers cleaner processing, lower deformation risk, and better dimensional stability, making it especially suitable for high-value precision parts.
The system supports 6 bar / 10 bar high-pressure nitrogen or argon cooling, depending on material requirements.
The equipment can be configured with graphite or molybdenum hot zones for temperatures up to 1320°C.
Vacuum high-pressure gas quenching furnaces can utilize graphite/molybdenum heating elements, with a maximum operating temperature of 1320℃ and temperature uniformity maintained within ±5℃. In terms of vacuum performance, the ultimate vacuum is 6×10⁻³ Pa, the pressure rise rate is 0.5 Pa/h, and the gas cooling pressure is 6/10 bar.
We offer standard models in the following sizes:
Effective area size ranges from 300×300×450 mm to 1000×1000×1500 mm.
Load capacity ranges from 100 kg to 1500 kg.
Heating power ranges from 80 kW to 550 kW.
For special furnace types and process requirements, we can also provide solutions and designs according to customer requirements.
