Factory Selling Haoyue Vacuum Tubular Furnace Vacuum Tempering Furnace Vacuum Porcelain Furnace

Vacuum oil quenching is to heat the workpiece in the vacuum heating chamber and move it to the quenching oil tank. The quenching medium is oil. The quenching oil in the oil tank is stirred violently to cool the workpiece quickly.

This model has the advantages that bright workpieces can be obtained through vacuum oil quenching, with good microstructure and performance, no oxidation and decarburization on the surface. The cooling rate of oil quenching is faster than that of gas quenching.

Vacuum oil is mainly used for quenching in vacuum oil medium of alloy structural steel, bearing steel, spring steel, die steel, high-speed steel and other materials.

Applications

PAIJIN Vacuum Oil Quenching Furnace is mainly used for bright quenching, hardening and tempering of alloy steel, alloy structure steel, die steel, spring steel, bearing steel, stainless steel, precision alloy steel; and sintering, bright annealing and vacuum brazing of various magnetic materials.

Characteristics

Paijin Vacuum oil quenching furnace is one of our star products, in our design, We have fully considered the characteristics of vacuum oiling process, strengthened the control of quenching oil temperature and frequency conversion control of mixing device, and can achieve perfect oiling conditions. At the same time, we have strengthened the sealing of the heating furnace and the insulation design of heating elements, reduced the pollution of heating elements and furnace caused by vacuum oil pollution, and prolonged the service life of the vacuum furnace.

1. High temperature uniformity: Its heating elements are evenly set all around the heating chamber makes its temperature difference is less than 5 degrees.

2.Capable of continuous production: it has separate heating room and quenching room.

3.Better cooling uniformity, less work piece deformation: Oil stirrer with variable frequency speed controller and flow guide mechanism.

4. It’s capable of : constant temperature quenching, isothermal quenching, convection heating, vacuum partial pressure.

5. Good mechanical action stability, big load weight, and the material vehicle is automatically operated.

6. With whole AI control system and an extra manual operating system.

7. Smart and easy for process programming, stable and reliable mechanical action, automatically, semi automatically or manually alarming and displaying the faults.
