Ultra-cryogenic cold box adopts advanced temperature control technology and liquid nitrogen dispersion technology to make the program heating, constant temperature and cooling process uniform and stable, and provide ultra-low temperature cooling environment and solutions. The application of German pulse spraying technology reduces energy consumption by 40%, greatly reduces the cost of use, and is more energy-saving and environmentally friendly.
In industry, the processing method of further cooling the material to 100℃～196℃ after ordinary heat treatment is called cryogenic treatment, which can reduce the content of retained austenite, promote the precipitation of fine carbides, and reduce the intergranular tensile stress. Improve more macro properties, such as: improve dimensional stability: the results show that the retained austenite of 95crl8 stainless steel is reduced from 35% to 10%; the hardness of W18Cr4V stainless steel at 625°C is increased from 57.9 to 63.9; high-speed steel and molds The hardness of steel increases by 1 to 2 degrees.
Nuoruida (Tianjin) science and Technology Co., Ltd. is committed to research, development, and sales of liquid nitrogen freezer. Using European technology, we provide a variety of equipment. The main equipment is liquid nitrogen Cryogenic treatment equipment, cryogenic freezer, liquid nitrogen cabinet freezer, liquid nitrogen tunnel freezer,sub-zero processing equipment, low temperature cold assembly equipment, cryogenic freezing equipment, and so on.
