Q:What is a cryogenic fast line

Cryogenic metal industry technology refers to the black metals, nonferrous metals, polymers, carbide and so on at cryogenic temperature heat preservation material, make it happen at room temperature and never happened in the process of heat treatment of the internal structure change, lead to the change of macro performance. For example: die steel, high speed steel, cemented carbide strength and toughness were improved after cryogenic treatment, and break through the traditional hardness and toughness of contradictory phenomenon, show the comprehensive performance improved. Domestic contribution to cryogenic technology research institute of Chinese academy of sciences, is the biggest should from the several aspects, such as equipment, mechanism, process research and extension of cryogenic technology, cryogenic in cutting tools, moulds, valves, and other industries extensively with the Chinese academy of sciences of physics and chemistry ? all the inseparable relations

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

It's just a rough process of producing oxygen through cryogenic technologyNitrogen can also be re cooled into liquid nitrogen -196 degrees.Liquid nitrogen can be used for some cryogenic treatmentIf the temperature is lower, can use liquid helium.Cryogenic applications

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

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.

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?

Copper alloy, hard alloy, plastic, glass and so on to improve the uniformity of low temperature, stable size, reduce deformation, improve service life

Q: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!
