Modular Combined Cryogenic Furnace Deep Cryogenic Furnace For Axletree/Bearing
Product description
Cryogenic is generally in the temperature range from -40℃ to -196℃. Cryogenic treatment generally uses liquid nitrogen refrigeration, and the method of ultra-low temperature treatment of the workpiece at a temperature below -130°C effectively improves the toughness of the workpiece. There are two methods of cryogenic treatment: One is that the workpiece is directly placed in liquid nitrogen. This method has a large thermal shock, which is easy to cause cracking of the workpiece; The other is the equipment produced by our DJL company, the cryogenic treatment of liquid nitrogen gasification. The processing temperature can reach -196℃, the processing effect is good, the toughness of the workpiece is greatly improved, and the workpiece will not be damaged.
The tempering furnace is used for general metal parts to be tempered in the air and used for quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons and aluminum plates. The outer shell is made of section steel and steel plate welded together. The trolley is welded by section steel and steel plate, the trolley reduces the heat radiation and convection loss through the soft contact with the furnace lining and the sand seal mechanism, and effectively guarantees the sealing of the furnace body.

The characteristics of DJL liquid nitrogen cryogenic treatment machine
1. With extreme low temperature, the lowest temperature is -196℃, which can greatly meet the requirements of cold assembly process.
2. Adopting the latest intelligent temperature control system, it can set the required temperature parameters, cooling, freezing and holding time according to the process requirements, and it has the function of process recording and remote monitoring.
3. The machine adopts advanced liquid nitrogen dispersing technology and unique cold air circulation system to make full use of liquid nitrogen cooling energy, so that the workpiece can be cooled evenly, stably and quickly.
Why take cryogenic treatment of the workpiece?
* To improve the hardness and strength of workpiece
* To improve the abrasion resistance of workpiece
* To improve the impact toughness * To improve the fatigue strength
* To improve the corrosion resistance of workpiece
* To improve the internal stress distribution of workpiece
* To ensure the dimension accuracy of workpiece
