Cryogenic treatment to improve what performance?
To improve the hardness and strength of the workpiece;Ensure the dimensional accuracy of the workpiece;Improve the wear resistance of the workpiece;
How many changes in the properties of the cryogenic metal?

I would like to ask how the process of cryogenic treatment
The air is compressed to 0.5MPa, or 22.5MPa, can reduce the water cooling, after expansion machine (piston or turbine), the temperature dropped to close to the liquid temperature to the fractionation tower after liquefaction, become rich liquid, the liquid oxygen into a fractionating tower, liquid oxygen, nitrogen is directly sent out after heat exchanger. Inlet air cooling.
What is the meaning of vacuum cooling in heat treatment
In order to eliminate residual austenite after heat treatment, after quenching or tempering
What is the meaning of deep frozen
In general, the frozen layer of our home refrigerator can only reach -18 degrees, but also slow freezing, slow freezing will have a great impact on food nutrition and flavor.
Can the cryogenic phase control the cooling rate?
2, the compressor refrigeration principle: the use of the suction pipe of refrigerant gas inhalation of low temperature and low pressure, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression, condensation, expansion and evaporation (endothermic) refrigeration cycle. The refrigerant of the compressor can be repeatedly used for a plurality of times, the consumption is relatively small, the power consumption in the refrigeration process is more, the cooling rate is relatively small, and the refrigeration temperature range is 0-80 DEG C. The above mentioned two kinds of refrigeration in the process of industrial production of cryogenic box, the use of liquid nitrogen refrigeration will be more. Liquid nitrogen refrigeration can be used in the temperature range from 0 DEG C to -196 DEG C. []
What is the meaning of cryogenic technology in the mechanical process, what is the specific practice?
Copper alloy, hard alloy, plastic, glass and so on to improve the uniformity of low temperature, stable size, reduce deformation, improve service life
Ultra low pressure casting mold useful, how to arrange the process? Thank you
Ultra deep cryogenic treatment process is mainly to eliminate the uneven stress in the process of heat treatment!Cryogenic treatment is mainly to eliminate internal stress or even internal stress! Can play a role in stabilizing the size!
