Q: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.

Q:Cryogenic treatment to improve what performance?

Improve the impact toughness of the workpiece;Improve the internal stress distribution and improve the fatigue strength;Improve the corrosion resistance of the workpiece;

Q:How many changes in the properties of the cryogenic metal?

The name of the processing content specification / processing content of the original service life (sub / piece) after the service life (times / pieces)1 milling cutter milling keyway 7.5-2NT 40034352 step drilling hole Phi: 1.2, 23, 1331004163 milling cutter milling air hole Phi 11.5, 32-2NT

Q: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

Q:What is the meaning of vacuum cooling in heat treatment

Placed for a period of time, known as cryogenic treatment, under normal circumstances are usually treated with liquid nitrogen.

Q:What is the meaning of deep frozen

So people use frozen ways to preserve food. Generally in a very short period of time, such as half an hour, so that the need to freeze the food quickly reach the specified ultra-low temperature, such as -30 ~-40 C.

Q: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. []

Q:What is the meaning of cryogenic technology in the mechanical process, what is the specific practice?

Treatment of -130 DEG C is said to be a new and strong treatment process of cryogenic treatment to improve the wear resistance and toughness of materials and to improve the overall service life

Q:Ultra low pressure casting mold useful, how to arrange the process? Thank you

Cryogenic treatment in the connector industry and plastic mold industry has a large number of applications, connectors and plastic products industry production temperature is not high, about 300 degrees! Thus the mold in the production of hot and cold alternating stress is less, after doing a cryogenic treatment, the role of the stability of the size of the more obvious, tube time is longer!
