Description

Technical Field

[0001] The utility model relates to the technical field of cryogenic treatment equipment for high-speed steel production, and particularly relates to a cryogenic treatment equipment for high-speed steel production. Background Art

[0002] Cryogenic treatment refers to a method of treating workpieces at a temperature below -130°C using liquid nitrogen as a refrigerant. Cryogenic treatment can significantly improve the toughness of workpieces without reducing their strength and hardness. The cryogenic treatment method is divided into two types: liquid method and gas method. By using a refrigerated metal cold treatment low-temperature box to cool the metal material, the mechanical properties and service life of the metal material can be improved. In a cascade mechanical refrigeration structure, after the metal parts are subjected to ultra-low temperature treatment at -120°C to -190°C, a large number of fine carbides with high dispersion are precipitated in the martensite matrix, and almost all the retained austenite is transformed into martensite, making the structure finer, thereby improving the hardness and strength of the parts. Especially the improvement of red hardness and wear resistance makes the service life of molds, tools, etc. increase several times. This process method is a common method for subsequent heat treatment abroad and has been used in China. The operation of taking out the high-speed steel after cryogenic treatment by traditional cryogenic treatment equipment is relatively troublesome and has a certain degree of danger, which is likely to cause frostbite to the users; there is a lack of a structure to enclose the cylinder body for the high-speed steel being cryogenically treated, and some small water droplets of boiling liquid nitrogen will splash out, affecting the surrounding environment.

[0003] In a cryogenic treatment equipment for high-speed steel production disclosed in the publication number CN216155921U, although the connection between the cryogenic treatment equipment and the cover cloth is made more stable and convenient by setting limit columns and limit blocks, and the limit is stable and firm, making it safer and more stable to use and convenient to open and close, reducing the time required to open the cover cloth and improving work efficiency. By setting clamping plates and clamping blocks, the connection between the protection plate and the control box is firm and convenient, providing safe and stable protection for the display screen to prevent it from being damaged and affecting viewing and use, reducing production efficiency, and improving the safety and convenience of equipment use.

[0004] However, this cryogenic treatment equipment for high-speed steel production has the following disadvantages:

[0005] The operation of taking out the high-speed steel after cryogenic treatment by the cryogenic treatment equipment is relatively troublesome and has a certain degree of danger, which is likely to cause frostbite to the users;

Thus, it achieves the effect of avoiding the boiling of liquid nitrogen for cryogenic treatment of high-speed steel, resulting in the splashing of small water droplets and affecting the surrounding environment.
