    Introduction

    Application

    1.Bright quenching of such materials as alloy steel, high-speed steel, tool steel, die steel, bearing steel, elastic alloy, stainless steel and so on.
    2.Vacuum treatment of magnetic material.
    3.High-temperature vacuum brazing and vacuum sintering.


    Vacuum oil-quenching furnace is graphite flue and heat screen is made of graphite felt. 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.


    Characteristics 

    1.Graphite rod, the heating component, is of long service life and easy maintenance.
    2.Slide valve features with good heat insulation and gas insulation.
    3.The structure of heating chamber is arranged scientifically, therefore it is heated uniformly and thermal losses are getting decreased with energy conservation.
    4.Stirring device of oil storage makes flow of quenching oil smooth and even, so the small deformation of components  can be guaranteed.
    5.Vacuum and cooling gas pressure can be adjusted in order to meet the demands of different materials.
    6.The transmission system of components is smooth and flexible in its operation on the safe side.

    7.The structure of furnace cover of gas cooling chamber is made of  interlocking tooth flange which gives a good seal of positive pressure and negative pressure.
    8.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.
