    The liquid nitrogen cryogenic box uses liquid nitrogen refrigeration, which is both economical and convenient. Cryogenic technology is an effective and economical new technology to improve the performance of metal materials. It is characterized by consumables, low power consumption, and no environmental pollution. At present, this technology has been widely used in aerospace, marine, military, manufacturing, automotive, hardware tools, sports equipment and other industries.

    The safety of liquid nitrogen cryogenic chamber operation: when the metal is hardened by heat treatment to the cooling process, the alloy and carbon are dissolved and combined and diffused to form austenite (Austenite). During the cooling process, due to the low temperature Martensite is formed, and because the final transformation point (Mf) of martensite is very low, for example: W18Cr4V (high-speed tool steel) has an Mf point of more than -190 ° C, so a large amount of austenite remains after quenching to room temperature The austenite reduces the hardness, wear resistance and service life of the metal. At the same time, due to the high brittleness of austenite, it is easy to cause metal fragmentation. Furthermore, there are many physical properties, especially thermal properties and magnetic properties.

    The liquid nitrogen cryogenic box has the characteristics of low noise, fast cooling, low failure rate, safer and more environmentally friendly.It uses liquid nitrogen as a cooling medium for cryogenic testing to improve the performance of the tested sample. It can be widely used in: biological Medical engineering, plant preservation, aerospace, electronic technology, scientific research institutes, environmental engineering, military industry and other fields.
