Cryogenic chamber industry can obtain liquid oxygen, liquid natural gas, etc.; it can effectively separate nitrogen, oxygen, argon, neon, krypton in the air, hydrogen in natural gas or water gas, methane, ethylene, etc. in petroleum cracked gas or cracked gas. Propylene etc. Widely used in petrochemical industry, liquefied gas, etc.
Cryogenic technology in the metal industry refers to the insulation of ferrous metals, non-ferrous metals, polymers, cemented carbides, and other materials at cryogenic temperatures to cause internal structural changes that have not occurred during normal temperature and heat treatment, resulting in Changes in macro performance. For example, the strength and toughness of die steel, high-speed steel and cemented carbide have been improved after cryogenic treatment, and it has broken through the traditional contradiction of hardness and toughness, which is manifested as an improvement in overall performance. The largest contribution to cryogenic technology research in China should be the Institute of Physics and Chemistry of the Chinese Academy of Sciences, which has conducted research and promotion of cryogenic technology from various aspects such as equipment, mechanism, and process. Physical and chemical are inextricably linked.
Process method
Cryogenic chambers usually use mechanical methods, such as throttling expansion or adiabatic expansion to obtain low temperatures as low as -210°C; adiabatic demagnetization can obtain low temperatures below 1K.
