Problems solved by technology

[0004] In the existing stainless steel pickling and phosphating treatment methods, the pickling method mainly includes soaking in the pickling pool and using a high-pressure nozzle to spray the pickling solution to the position to be treated. Among them, the high-pressure nozzle spraying method can greatly reduce the consumption of pickling solution It is a relatively environmentally friendly method to reduce the amount of waste water in the pickling process and soak in the pickling tank. However, for the inner wall of stainless steel pipes, it is difficult for technicians to use high-pressure nozzles to fully and evenly pickle the inner wall of stainless steel pipes. , especially the sprayed pickling solution will slide from the inner wall of the stainless steel to the bottom due to its own weight, and accumulate, which will easily cause excessive corrosion at the bottom of the stainless steel, making the surface treatment of the stainless steel fail

Embodiment 1

[0046] see Figure 1-7 , a stainless steel pipe surface treatment process, mainly comprising the following steps:

[0047] S1, pretreatment, put the treatment ball 1 into the pickling tank, so that the surface of the treatment ball is infiltrated by the pickling solution;

[0048] The processing ball 1 includes an egg-shaped spherical shell 101, and a plurality of liquid storage tubes 102 are fixedly connected to the outer side of the egg-shaped spherical shell 101. The plurality of liquid storage tubes 102 are in a three-dimensional spiral shape, and the plurality of liquid storage tubes 102 are entangled in an egg-shaped The outer surface of the spherical shell 101 forms a three-dimensional space structure, which is used to temporarily store the pickling solution. An ultrasonic generator is installed at the bottom of the pickling tank, and the ultrasonic wave generated by the ultrasonic generator accelerates the pickling solution into a plurality of storage pipes 102. The s...

Abstract

The invention discloses a stainless steel pipe surface treatment process, and belongs to the field of stainless steel pipe treatment technologies. According to the stainless steel pipe surface treatment process in the scheme, treatment balls are mixed in a sprayed pickling solution, the pickling solution is stored through a liquid storage pipe on the surface of an egg-shaped spherical shell, and in the pickling solution spraying process, the treatment balls can be sprayed out together; after the treatment balls make contact, impact is generated and the treatment balls are broken, the treatment balls adhere to the inner wall of a to-be-treated pipe under the action of the surface tension of the pickling solution, then under the action of an air bag, a three-dimensional space structure formed by the liquid storage pipe collapses, the pickling solution is released, and pickling infiltration is conducted; and finally, a transmission roller is rotated, the liquid storage pipe is used for cleaning the inner wall of the to-be-treated pipe, and impurities generated by acid pickling are stripped from the inner wall of the to-be-treated pipe, so that the success rate of stainless steel surface treatment can be greatly increased, the phenomenon of uneven acid pickling is not prone to occurring, and the performance of subsequent machining of the stainless steel pipe is improved.

Description

technical field [0001] The invention relates to the field of stainless steel pipe treatment technology, more specifically, relates to a stainless steel pipe surface treatment technology. Background technique [0002] Stainless steel has excellent characteristics such as unique strength, high wear resistance, superior anti-corrosion performance and not easy to rust. Therefore, it is widely used in industry, food machinery, electromechanical industry, household appliance industry and home decoration and fine decoration industry. The application and development prospects of stainless steel will become wider and wider, but the application and development of stainless steel largely depends on the development of its surface treatment technology. [0003] The surface treatment process of stainless steel is usually to endow stainless steel with some new functions, such as pickling and phosphating treatment of stainless steel, which will greatly increase the surface properties of st...
