Product Description

Product Description

Vacuum double chambers low pressure carbonitriding oil quenching furnace
Vacuum carburizing is to heat the workpiece in vacuum. When it reaches the temperature above the critical point, it will stay for a period of time, degass and remove the oxide film, and then pass in the purified carburizing gas for carburizing and diffusion. The carburizing temperature of vacuum carburizing is high, up to 1030 ºC, and the carburizing speed is fast. The surface activity of carburized parts is improved by degassing and deoxidizing. The subsequent diffusion speed is too high. Carburizing and diffusion are carried out repeatedly and alternately until the required surface concentration and depth are reached.

Vacuum carburizing depth and surface concentration can be controlled; It can change the metallurgical properties of the surface layer of metal parts, and its effective carburizing depth is deeper than the actual carburizing depth of other methods.

APPLICATIONS
The vacuum double-chambers low-pressure carbonitriding oil quenching furnace has various functions including carburizing, carbonitriding, oil quenching and pressure air-cooling. Is mainly used for quenching, annealing, tempering the die steel, stainless steel, high-speed steel, high-alloy steel tools; and carburizing, carbonitriding quenching the medium or low-carbon alloy steel. It can used for one-time carburizing, pulse carburizing and other carburizing and cabonitriding processes. 

 

Characteristics

1.High intelligent and efficient. It is equipped special developed vacuum low-pressure carburizing simulation software.
2.Good temperature uniformity. heating elements are evenly arranged 360 degrees around the heating chamber.
3.No carbon black pollution. The heating chamber adopts the external insulation structure to prevent the pollution of the carbon black in carburizing process.
4.Good cooling uniformity and speed,less workpiece deformation. Its quenching stir device driven by frequency conversion and with guiding device. 5.Its functions including:Thermostatic oil quenching, Isothermal quenching, convective heating, vacuum partial pressure.
6.Frequency conversion stirring quenching, channeling quenching, pressure quenching.
7.Good carburized layer thickness uniformity, Carburizing gas nozzles are evenly arranged around the heating chamber, and the thickness of carburized layer is uniform.
8.Smart and easy for process programming, stable and reliable mechanical action
9.Automatically, semi-automatically or manually alarming and displaying the faults.
