    Characteristic

    01

    Limit vacuum up to 10-4 Pa level, combined with multiple sealing technology, to ensure no oxidation, no decarbonization during heating process.

    Multi-zone independent control heating + closed-loop temperature control system, furnace temperature uniformity ≤±5℃, to ensure uniform change of material structure.

    Optional convection heating function, in the low temperature section can significantly improve the heating rate and furnace temperature uniformity.

    Through different cooling inert gas (nitrogen, argon, helium) and under different cooling pressure, combined with high-speed, large flow fan to quickly cool the workpiece, cooling speed is controllable.

    The cooling gas flow can be reversed, and the gas deflector is installed to eliminate part of the cooling dead Angle and achieve uniform cooling of the products in the heating room.

    The surface of the heating chamber is made of graphite composite material CC, which is resistant to high temperature and high pressure airflow and has a long service life.

    Choose a flexible opening method of the furnace door according to the customer's on-site requirements (such as the door position left and right direction, automatic or manual opening).

    Integrated PLC, with program controller or computer interface, touch screen, recorder and other real-time monitoring furnace vacuum degree, temperature, pressure and other data, support remote fault diagnosis and process tracing.

    With high pressure fast cooling, vacuum cleaning and intelligent control as the core advantages, vacuum high pressure gas quenching furnace provides efficient solutions for precision quenching of high value-added workpieces, helps enterprises break through the material performance limit, and becomes the preferred equipment in aerospace, precision mold and other high-end manufacturing fields.

    Frequently Asked Questions

    What is the maximum vacuum level of this gas quenching furnace?

    The furnace can achieve a limit vacuum up to the 10-4 Pa level. Combined with advanced multiple sealing technology, it prevents oxidation and decarbonization during the heating process.

    How is temperature uniformity controlled within the furnace?

    Temperature uniformity is maintained within ≤±5℃ through a multi-zone independent heating control system combined with closed-loop temperature control. An optional convection heating function is also available to improve heating rates and uniformity in the low-temperature range.

    What cooling media and pressures does the system support?

    The system supports inert cooling gases such as Nitrogen, Argon, and Helium. Gas cooling pressures can range from 0.87 to 10 bar abs depending on configuration, utilizing high-speed, large-flow fans with optional reversible gas flow direction to eliminate cooling dead zones.

    What materials are used for the heating chamber?

    The surface of the heating chamber is constructed with graphite composite material CC. This material is highly resistant to both high temperatures and high-pressure airflows, ensuring a long operational service life.

    Can the specifications of the quenching furnace be customized?

    Yes. We support custom configurations for the effective working area dimensions, maximum operating temperature, working vacuum levels, gas cooling pressure, and other parameters to suit your specific production requirements.
