    Introduction


    Application

    Vacuum carburizing furnaces are twin-chambered horizontal vacuum heat treatment equipments with both oil-cooling and gas-cooling functions. It is mainly applied in vacuum carburizing and quenching of matching parts such as gear, oil pump and nozzle tip, and in oil quenching, gas quenching, annealing, brazing and sintering of many precision machine parts of high-speed steel, high-alloy tool steel, high -alloy die steel and insert bearing.


    Characteristics

    1.Graphite rod, the heating component, is of longer service life and easier maintenance than graphite cloth. 
    2.Slide valve features with better heat insulation and gas insulation, and more advanced technology than flap valve.
    3.The system operates by mechanical transmission which is more exact and reliable and dependable than hydraulic circuit. It is of low failure rate, simple and convenient maintenance. Featuring with unique form of bifurcation, the feeder is not dropped into gasoline tank when oil-quenching operates. Therefore the heating chamber is prevented from being polluted, the volume of cooling chamber is reduced at a large scale, nitrogen which is the cooling gas is saved, and the operation cost of vacuum furnaces is reduced.

    4.Electrical control system features with high automation with reliability and stability. Temperature is controlled by smart temperature controller and the operation is controlled by program controller. 
    5.The system is controlled by PLC and touch screen shows the working condition. It is easy to choose the manual operation or the automatic operation. The alarm system responds automatically if the numerical value of temperature, water pressure or air pressure is found greater than setting value.
