    Frequently Asked Questions FAQ

    What are the advantages of the bottom lift loading system?

    The bottom lift loading system with a vertical furnace reduces the required floor space, facilitates efficient loading and unloading of heavy workpieces, and significantly reduces manual operation intensity.

    How does the furnace prevent surface oxidation during heating?

    By heating the workpieces under a high vacuum range of 10-2 to 10-6 mbar, the system effectively prevents surface oxidation and decarbonization, ensuring a pure and stable process environment.

    What is the temperature uniformity of this vacuum furnace?

    The furnace achieves a temperature uniformity of ±5℃. This is accomplished through multi-zone independent temperature control combined with an advanced PID algorithm, ensuring consistent processing for large workpieces.

    Can the cooling speed of the workpieces be controlled?

    Yes. By utilizing different cooling inert gases (such as nitrogen, argon, or helium) under varying cooling pressures, and combining them with a high-speed, large-flow fan, the cooling speed is fully controllable.

    Why does the load bearing table rotate during operation?

    The table can rotate during both the heating and cooling stages to ensure the best possible temperature uniformity across the parts, which effectively controls and minimizes workpiece deformation.

    Are custom sizes and specifications available for these models?

    Yes, we support customization for the effective working area size, maximum temperature, working vacuum level, gas cooling pressure, and other parameters to match your specific production requirements.
