Q:What is a cryogenic fast line

Equipment is compressor, heat exchanger and expander (or throttle). The compressor and expander generally use a reciprocating or turbine. Commonly used heat exchanger coil type, shell and tube type or plate heat exchanger. Deep freezing technology, can the nature of the study of materials near absolute zero, and can be used for the separation of liquid and gas mixture of gases. Industry can get liquid oxygen, liquid, gas, etc.; Can be effectively separated from the air

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?

Name material application effect1 the average number of W18Cr4V drill holes is 2.87 times that of untreated2 the number of drill holes in W6Mo5Cr4V2 twist drill is increased by 84%3 15 W18Cr4V from each processing to raise to4 M16 punching bit W12RE each 20 thousand to 40 thousand pieces5 M16 punching bit 65Nb each 1 thousand to 3 thousand pieces6 scissors T8, T10, T12 scissors silicon steel sheet life increased by more than 2 times7 milling 434 stainless steel blade C-2 carbide service life increased by 400%8 bearing steel GCr15 wear resistance increased by 3 times9 M3*0.5 Cr12MoV from a pair of processing to improve the 8000 pieces10 silicon steel sheet die Cr12 die life doubled11 hot stamping die 3Cr2W8V increased by 2.5% compared with the conventional AB, B increased by, AK increased by 4.9%12 M22 trimming die 012A1 each from 8000 to 30 thousand pieces13 processing silicon steel sheet die Cr12 processing sheet number increased from 300 thousand to 600 thousand

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

In order to eliminate residual austenite after heat treatment, after quenching or tempering

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?

If it is just a simple container or box, it is difficult to control the temperature. The program can control the temperature of cryogenic equipment, can also control the cooling rate

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

High speed steel W18Cr4V cryogenic hardness, impact toughness and wear resistance are significantly improved with the use of its manufacturing tool life increased by 2~5 times

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

While casting field production high temperature is about 660 degrees, some die casting production Aluminum Alloy temperature of 740 degrees, copper alloy die-casting production temperature even up to about one thousand degrees, the temperature and the ambient temperature, the temperature fluctuation is bigger, hot and cold alternating stress caused by the greater! That is, the stress produced in the production process is very large, even if the cryogenic treatment, the stability of the role of the size of the casting mold and plastic mold is not obvious! As for how you choose, you might as well try!
