FAQ

What is the meaning of deep frozen
Frozen food can make the flavor and nutrient retention is best, and it is said that at -35 deg.c, food oxidation reactions are very slow, that is to say deep freezing over the food nutrition and flavor of fresh food with little difference. In short, deep frozen to fresh.
What is the meaning of vacuum cooling in heat treatment
In order to eliminate residual austenite after heat treatment, after quenching or tempering
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;
I would like to ask how the process of cryogenic treatment
Biology: fast cooling, can prevent the crystallization of cells in the water, does not destroy the cell organization. In the preservation of sperm, organ preservation, food preservation, preservation of certain life and so onMedical treatment: cryotherapy, treatment of certain skin diseasesSpace: the space environment simulation, satellite ground test station, using liquid helium, create -200 degrees of low temperature.Noise: high sensitivity radar telescope, using liquid helium cooling, receiving device, noise reductionVacuum: the use of cold well technology can get high vacuum
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. []
How many changes in the properties of the cryogenic metal?

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!
What is a cryogenic fast line
Broadly, cryogenic means - the temperature under 100 ℃, in industry can be divided into gas liquefaction technology, chemical industry and material industry of cryogenic treatment.
