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?

To improve the hardness and strength of the workpiece;Ensure the dimensional accuracy of the workpiece;Improve the wear resistance of the workpiece;

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?

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

How many changes in the properties of the cryogenic metal?

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!

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
