Embodiment Construction
[0018] In order to illustrate the content of the present invention more clearly, specific examples are used to illustrate the following, and the specific examples do not limit the scope of the content of the present invention.
[0019] An environment-friendly stainless steel casting surface vibrating and ultrasonic cleaning process is characterized in that it comprises the following steps:
[0020] (1) After cutting, shot blasting, welding, solid solution treatment, and shot blasting, the cast stainless steel castings are placed in a vibrating machine, added with HX-O vibrating cleaning agent, and vibrating cleaning is performed under the condition of PH 7-9 To remove the burrs and scale on the surface;
[0021] (2) Perform stainless steel shot blasting on the stainless steel castings after vibration cleaning;
[0022] (3) After the shot blasting treatment, the stainless steel castings are pre-cleaned with clean water added with cleaning agent to wash away the large particles...

The invention discloses an environment-friendly stainless steel casting surface polarized light and ultrasonic cleaning process. Stainless steel castings are subjected to cutting, shot blasting, welding and solid solution treatment, after the shot blasting is carried out, polarized light cleaning is carried out firstly, a special polarized light cleaning agent is matched, and shot blasting treatment is carried out after the polarized light cleaning is carried out; then the stainless steel castings are cleaned by clear water, ultrasonic cleaning with specific ultrasonic cleaning agents are added, the glossiness and the brightness of the surface of the cleaned stainless steel castings are high, and the pH value of the cleaned wastewater is close to 7, the pollution of the acid wastewater isavoided, and the odorless and acid-free flue gas is environment-friendly and clean.
Description
technical field [0001] The invention relates to the technical field of stainless steel castings, in particular to an environment-friendly surface vibration and ultrasonic cleaning process of stainless steel castings. Background technique [0002] Most of the existing valve castings are produced by stainless steel castings, and the existing stainless steel castings need to be cleaned and treated by pickling process in order to obtain the gloss and smoothness of the surface of the valve castings. Brightness, but the existing pickling operation often brings a large amount of acid waste water, which pollutes the environment and is not conducive to environmental protection. Contents of the invention [0003] In order to overcome the defects of the above methods, the present invention provides an environment-friendly stainless steel casting surface vibrating and ultrasonic cleaning process. [0004] The technical solution adopted by the present invention is: an environment-frie...
