How to clean the surface of stainless steel castings

Generally speaking, the surface removal of stainless steel castings can be divided into two types: dry and wet, dry cleaning is mainly shot peening and rust removal, and wet cleaning is a little bit of hydraulic press sand cleaning and water sand cleaning.

 

The dry cleaning method is a friction treatment method dominated by shot blasting to remove rust on the surface of stainless steel castings. in a simple way, shot blasting and rust removal is driven by air compression, so that the shot wheel breaks and gushes to the surface of stainless steel castings at a certain rate, eliminating sand and zinc ash on the surface, but this kind of friction removal is due to high efficiency and low efficiency, uneven removal, poor actual effect and so on. It has long been selected by many factories and has been basically eliminated.

 

The wet emotional method is mainly based on the basic principle of the use of electro-hydraulic hammer, which carries out two-color charge and discharge according to the unique electric level placed in the water, resulting in a large impact of hydraulic transmission. Because the surface adhesion of stainless steel castings is different from that of castings in ductile displacement coefficient and vibration frequency, so that the sand can be cleaned. Aiming at the complicated stainless steel castings such as deep hole, buried hole and inner wall, it has a more reasonable cleaning effect. It is a widely used surface removal method for a series of castings within stainless steel castings at the present stage.

 

Above are two common ways to remove the surface layer of stainless steel castings. Here we must remind everyone that these two removal methods are not only for stainless steel castings. The vast majority of metal casting products must be removed on the surface layer after production, processing and forming, which is an indispensable process in metal casting products. The key effect of Z is to remove a series of residues such as sand and zinc ash on the surface of metal castings, which promotes more and more stainless steel metal gloss on the surface of stainless steel castings to achieve the product implementation standards. therefore, the removal of the surface layer of stainless steel castings is very important, and we must carry out it in an appropriate way when removing the surface layer of stainless steel castings. In order to ensure the quality of stainless steel castings.
