Two Methods for Surface Cleaning of Stainless Steel Castings

Generally speaking, the surface cleaning of stainless steel castings is divided into two categories: dry and wet. The dry cleaning method is mainly shot blasting, while the wet cleaning method mainly includes hydraulic sand cleaning and water sand cleaning. Weifang Kailong Pump Industry Co., Ltd. will introduce the surface cleaning methods of dry and wet stainless steel castings for your reference.

Dry cleaning method is to clean the surface of stainless steel castings by friction treatment based on shot blasting. Shot blasting is simply to use compressed air as the power to make the projectile spray on the surface of stainless steel castings at a certain speed to remove sand and iron oxide on the surface. However, this friction cleaning method has been adopted by many factories due to low efficiency, uneven cleaning and poor effect, it has almost been eliminated.

The wet-type reasoning method is mainly the principle of electro-hydraulic hammer effect, which discharges the high-voltage pulse generator through special electrodes placed in water to produce large hydraulic impact. Because the elastic modulus and vibration frequency of the stainless steel casting surface adhesion and the casting itself are different, so as to achieve the purpose of sand cleaning. For stainless steel castings with complex shapes, such as deep holes, blind holes, and inner cavities, it has a more effective cleaning effect. It is the surface cleaning method for a series of castings including a stainless steel castings that are currently widely used.

The above are two common cleaning methods for the surface of stainless steel castings. It is necessary to remind everyone here that these two cleaning methods are not only for stainless steel castings, but also for the vast majority of metal casting products. Cleaning the surface is an indispensable process in metal casting products. Cleaning the surface of castings, * The main function is to remove a series of impurities such as sand and iron oxide scale on the surface of metal castings, so that the surface of stainless steel castings becomes stainless steel metallic luster and reaches the implementation standard of products. Therefore, the surface cleaning of stainless steel castings is very important. Everyone must follow the correct method when cleaning the surface of stainless steel castings. To ensure the quality of stainless steel casting products.
