  • 1.Working in vacuum environment, no oxidation, no decarburization and exceedingly good surface quality;

    2.Vacuum purification of product surface, can produce improvement for carburizing efficiency, less consumption of carburizing atmosphere and low production cost;

    3.Double chamber vacuum sealing design is adopted, the heating chamber is kept in vacuum state normally, without contacting with large air and moisture, the heater and insulation materials will not be oxidized, and the service life is long;

    4.The quenching process is carried out separately in the front room. The heating room is kept in a high temperature state for a long time. The heating time is short, energy is saved, and high-quality heat treatment production can be carried out repeatedly;

    5.The cooling is speedy and homogeneous; the product can be quickly transported to the cooling chamber, and is rapidly cooled in the oil tank. The oil tank has a diversion structure. The mixing effect of the invert able motor is uniform, the quenching strength is high, the cooling effect is good, and the product has a wide range of applicable properties;

    6.High temperature carburizing process can be adopted, with the maximum carburizing temperature of 1050 ℃. It can be used for carburizing stainless steel and deep layer carburizing;

    7.The material transportation process is stable and reliable, and the whole process of work-piece loading - cooling chamber - heating chamber - cooling chamber oil tank - discharging is stable and reliable, without jitter and jamming, and the long-term operation reliability is extremely high.
