FAQ

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.
What is the meaning of vacuum cooling in heat treatment
Use a low temperature of 100 degrees below zero
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?
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. []
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
Ultra low pressure casting mold useful, how to arrange the process? Thank you
The size stability of die casting die is mainly solved by the following aspects:1, in the die casting process and mold temperature stability under the premise of the mold size! To ensure product size!2, in the design of die casting products, according to the way the product and the simulation of the temperature field, the type of product, the direction of contraction and so on to develop the contraction ratio, the general product shrinkage rate of about 5/1000! Step by step cumulative experience!3, die casting mold in the production period of time, (for example, 5 thousand to 10 thousand times), can do stress treatment, ABP treatment, etc.! In order to reduce the internal stress in the production process of the mould, it can achieve the purpose of stabilizing the size, preventing the fracture and increasing the service life of the die!Want to help you!
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
