Analysis on the use cost of liquid nitrogen cryogenic treatment equipment

　　 liquid nitrogen cryogenic treatment equipment was previously applied to worn tooling materials, and later expanded to alloy steel, cemented carbide, etc., which is one of the current strengthening and toughening treatment technologies. According to its working mechanism, the equipment transforms the retained austenite in the internal structure of the metal material into martensite, precipitates dispersed carbides in the martensite, eliminates the residual stress in the martensite, and improves the martensite matrix Hardness and wear resistance. The increase in hardness is due to the transformation of part of the retained austenite into martensite, and the increase in strength and toughness is due to the precipitation of -fe3c, the reduction of martensite carbon content and the reduction of martensite lattice distortion. With the promotion of this technology in our country, this equipment has been widely used in all walks of life.

　　The equipment can significantly improve the wear resistance, toughness and dimensional stability of metal workpieces, and double the service life of the workpieces. The improved teaching effect of cold treatment technology is to penetrate into the interior of the treated part (the overall economic effect), not limited to the surface, so when the cutting tool is re-grinded and reused, the modification effect of the workpiece will not be invalidated; the shape and size of the workpiece are not only designed by themselves It will not affect and cause social changes, and it has the effect of enhancing the stability of different dimensions and reducing the quenching stress; the process management system is more convenient, the power consumption is less, and it is not restricted by the shape and size of the workpiece, and the operation method is simple; there is no environment It is a completely environmentally friendly construction technology that causes pollution.

　The equipment is customized according to the production volume of the enterprise and determined according to the demand. Generally speaking, it is cheaper than the traditional ones. The liquid nitrogen cryogenic treatment equipment is very simple to operate and can be easily connected to the existing production line. The structure is relatively simple, the system working pressure is small, there are few failures, there is no high-pressure equipment, and the quality of frozen food is high.

　　 1. Equipment capacity and utilization rate: The utilization rate of equipment technology is getting higher and higher, and the cost is lower.

　　2. Equipment process: The lower the temperature, the more liquid nitrogen that needs to be consumed, and the higher the cost risk; the longer the use time, the more liquid nitrogen needs to be consumed, and the higher the cost analysis;
