  • 1.Horizontal single chamber design is applied with compact structure, and furnace door opening mode can be designed according to user requirements;

    2.The cooling gas adopts the top-bottom reversing design to effectively ensure the uniform cooling performance;

    3.Completely imported cooling circuit design, with large quantity of gas flow.

    4.The quenching motor is designed with vacuum water-cooled seal, which has short starting time, small starting current and no special requirements for power grid;

    5.The heaters are distributed in ring section to effectively improve the uniform performance of furnace temperature;

    6.Function of convection heating is possessed. As convection fan is started and operated under a certain pressure, the heating speed and furnace temperature uniformity can be significantly improved in the low temperature section.


  • Loading→ vacuumizing→ convection heating→ vacuum heating→ partial pressure heating→ high pressure quenching→unloading.
