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?
Improve the impact toughness of the workpiece;Improve the internal stress distribution and improve the fatigue strength;Improve the corrosion resistance of the workpiece;
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.
Can the cryogenic phase control the cooling rate?
1, the principle of liquid nitrogen refrigeration: storage of liquid nitrogen in the container through the liquid in the sublimation of heat to take away the heat of the workpiece heat. Liquid nitrogen refrigeration can not be reused after the need to add a new liquid nitrogen, a large range of cooling rate, cooling temperature range of 0-196 degrees C.
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
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
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!
