Product Description

Product Description

Vacuum Oil Quenching 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 mainlly 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.

Relative information

 

Hi,my friend, thanks for checking Paijin Vacuum furnaces. I will show you why our products are  your best choose.

Technical advantages:

1. Energy saving: By using our self-owned registered patented technology of energy saving, our furnaces saves 20%-40% energy than other brands in heating. Reduces muh cost.
2. High Intelligent Control system:All our furnaces are equiped with our high intelligent control system, it can realize one button operation by the recorded data and record the processs in Computer.
3. Advanced Voltage control technology, lower current in same power to avoid the melting of cables, and raise safety level.

Processes
Paijn vacuum furnaces are basically composed by Furnace body, heating system, vacuum system, gas recharge system and control&measure systems.

A standard vacuum furnace would able to used for the basic processes like:
Annealing
Tempering
Brazing
Sintering
Hardening
In Vacuum and Atmosphere conditon.

By adding some fuction parts, it will realize or strengthen its ability in
Carburizing
Debinding
Nitriding
Oil hardening
Low temperature difference brazing (≤±3ºC)

Hot zone materials:

Graphite Hot Zones
Graphite hot zones are long-lasting and can deliver excellent ROI. They are robust, economical to repair and incorporate hearth designs with high creep strength.

All-Metal Molybdenum Hot Zones
If your process is susceptible to graphite contamination, a molybdenum hot zone can meet your needs. Our moly hot zone elements feature a "double-U" profile which makes them easy to install and replace.

Custom Constructions
We offer custom hot zone construction such as graphite insulation with moly heating elements, for applications with unique requirements.

Quality Control:
Quality is the spirit of the products, is the key point decide a factory's future.Paijin take quality as the most priority issues in our daily work.To ensure the good quality of our products, we paid much attention on 3 aspects.

1. Most important: Human. Human is the most important point in every work. We have complete training courses for every new worker, and we have rating system to rate every worker to a level (junior, middle, high), different level workers are apponted to different jobs with different salary. In this rating system, it's not only the skills, but also rate in responsibility and error rate, executive power etc. By this way, workers in our factory are willing to do the best in his work.And strictly follows the quality management rules.
2. Best materials and components: We only purchase the best materials on market, we know that saves 1 dollar in material would cost 1000 dollars in final. The key parts like electric components and pumps are all brand products like Siemens, Omron,Eurotherm, Schneider etc. For the other parts made in China, we choose the best factory in industry and signed product quality guranntee contract with them,to ensure every component every parts we use in the furnace is the best quality products.
3. Strict Quality management: We have 8 quality check points in the processes of furnace producing, Examination in each check point is carried by 2 workers and 1 factory manager is responsible for it. In these check points, materials and components, and every aspects of the furnace are double checked to ensure its quality. At last, before the furnace leaves factory, it should be final checked with heat treatment experiments.

Packages and Shipping:
We have much experience in the packages and shipping, our furnaces are usually shipped by rail or by sea. Sometimes small parts my shipped by air. The main body will be fixed in the container by steel ropes and other parts will be packaged in wooden cases.
