Description

Technical Field

[0001] The utility model relates to the technical field of SD process, in particular to cooling equipment for SD process. Background Art

[0002] The SD process is a low-temperature supersaturated solid solution diffusion (Supersaturation-Diffusion ion) treatment process. Its essence is to place stainless steel in a high-concentration carbon and nitrogen atmosphere at a temperature of 400-480°C. A supersaturated solid solution hardened layer with a thickness of 20-50μm is formed on the surface of the stainless steel through diffusion. The C and N content in the solid solution is as high as 10-12Wt.%. In this way, a high hardness of ≥1000HV0.1 can be stably obtained, and the maximum hardness can reach 1750HV0.05, which is equivalent to the hardness of cemented carbide and is the highest hardness value currently achievable by similar processes.

[0003] The most notable feature of the SD process for stainless steel surface hardening is that its treatment temperature is much lower than that of traditional nitriding and carburizing. At this temperature, a single solid solution phase is formed, rather than chromium compounds, and the solid solution concentration of chromium in the hardened layer does not decrease. Therefore, the SD process not only achieves high hardness, but also achieves corrosion resistance that equals or exceeds that of the substrate, while maintaining the substrate's original plasticity, toughness, and dimensional accuracy.

[0004] According to authorization publication number CN 214120471 U, a high-speed steel cooling device is disclosed, belonging to the technical field of high-speed steel processing equipment. This device solves the problem of nitrogen not being evenly distributed on the surface of the high-speed steel during the existing high-speed steel cooling process. The high-speed steel cooling device includes a body having a cavity within the body for accommodating the high-speed steel for cooling. The device also includes a base support disposed within the cavity, a nitrogen outlet pump, several rotating shafts, and a conveyor belt. Two support plates are provided on either side of the base support. The conveyor belt is mounted on the support plates via rotating shafts, one of which is connected to a drive motor. The drive motor is activated to cause the conveyor belt to slide. The nitrogen outlet pump is fixed to the body and is equipped with several nozzles. Compared to the prior art, the conveyor belt in this high-speed steel cooling device has leak holes formed on the conveyor belt, allowing the surface of the high-speed steel in contact with the conveyor belt to be exposed to nitrogen for cooling, thereby improving cooling efficiency and achieving more uniform cooling effect.

[0005] The above patent uses liquid nitrogen to cool the steel during use, which causes a large thermal shock and may cause cracking of the steel body, affecting the normal use of the steel parts. Therefore, a cooling device for the SD process is now needed. Utility Model Content
