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 relationss
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 applicationss
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.s
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!s
