Description

Technical Field

[0002] Sherardizing is an anti-corrosion process that uses diffusion to obtain an iron-zinc alloy protective layer on the surface of steel parts. Compared with hot-dip galvanizing, the sherardizing layer has the advantages of uniform shearing layer, high hardness, good wear resistance, controllable shearing layer thickness, high dimensional accuracy, and better corrosion resistance. The sherardizing process has very strict requirements on temperature, and it is essential that the temperature of each area is the same or the temperature difference is less than the threshold. However, the heating means used in the prior art often cannot achieve relatively uniform heating, and the temperature difference between each area is large.

[0003] In addition, the application document with publication number CN218232543U mentions a new type of vacuum zinc-diffusion device with lateral feeding and discharging. During the use of the utility model, the device adds protective gas during the zinc-diffusion process through the cooperation of the protective gas storage tank and the gas pipe, so as to protect the surface of the workpiece and improve the quality of the product. In addition, through the cooperation of the induced draft fan, the exhaust duct, the composite filter screen and the activated carbon filter element, the internal gas is filtered and discharged to prevent pollution, and the safety is higher.

The specific defects are as follows: The filter plate net and the activated carbon filter element are not easy to replace after saturation.

[0004] Therefore, it is particularly important to design a vacuum sherardizing device to change the above technical defects and improve overall practicality. Utility Model Content
