Product Description

In the past, during hot-fitting, when it could not be installed, workers often needed to use a sledgehammer or a crane to lift heavy objects for impact to complete the assembly. This operation has a certain degree of danger. Break. With cold assembly, a small workpiece can be completed by one person, just put the parts into the base hole. During the hot-fitting process, the base hole parts need to be heated and then cooled in the air. This process is equivalent to performing a low-temperature annealing treatment on the parts, which reduces the hardness and strength of the parts. Cold assembly is equivalent to performing a cold treatment on the parts. After the parts are cold treated, the following can be obtained:
a. Lower austenite can make the product invariable for a long time;
b. Increased hardness and averaging;
c. Improve the performance of machinery;
d. Stable size;
e. Increased magnetism;
f. Enhanced wear resistance.

Thereby improving efficiency and reducing the labor intensity of workers.

The cryogenic process of the ice-cooling machine for the heat treatment of cutting tools can improve the performance of metal materials. Effective and economical technical indicators. During the cryogenic process of martensite, the retained austenite is transformed, and the performance of the finely dispersed carbides changes in the material , It can hinder the dislocation movement of ultra-fine carbides, thereby strengthening the matrix structure and exerting the grain boundary strengthening effect, which has been improved in the following three aspects: impact toughness, wear resistance, and dimensional stability.
