As a high-quality material, sanitary stainless steel pipe has a wide range of applications in food, medicine, chemical industry and other fields. In order to ensure its surface quality and corrosion resistance, polishing becomes an indispensable process. This article will delve into the principle and process of polishing the most sanitary stainless steel pipe, in order to provide a useful reference for related industries.
First, the principle of polishing.
Polishing of sanitary stainless steel pipes is a process in which the oxide layer on the surface is dissolved and removed by abrasive particles by the relative movement with the surface of the workpiece, which generates high pressure and high temperature. In this process, the abrasive particles produce strong friction with the surface of the workpiece, forming local high temperature and high pressure, which promotes the plastic deformation of the oxide layer and is removed under the mechanical action of the abrasive particles. As the polishing process progresses, new metal surfaces are constantly exposed and gradually smoothed out by friction.
Second, the polishing process.
Abrasive selection. Abrasives play a vital role in the polishing process. In order to achieve the ideal polishing effect, it is necessary to select the appropriate abrasive according to the material, hardness, surface quality and other requirements of the workpiece. Commonly used abrasives include corundum, silicon carbide, alumina, etc., which have high hardness and wear resistance, and can effectively remove the oxide layer on the surface of stainless steel pipes.
Polishing parameters. The reasonable setting of polishing parameters has an important impact on the polishing effect. Common polishing parameters include abrasive grain size, polishing pressure, polishing speed, etc. These parameters need to be adjusted according to the actual situation to achieve the best polishing results. During the polishing process, it is also necessary to pay attention to controlling the temperature of the workpiece to prevent deformation of the workpiece or deterioration of surface quality caused by excessive temperature.
Polishing process.
The polishing process of sanitary stainless steel pipes generally includes the following steps: pretreatment, rough polishing, semi-fine polishing, fine polishing and post-treatment. The pretreatment stage is mainly to remove oil, rust and other impurities on the surface of the workpieceThe rough polishing stage is mainly to remove the raised part of the surface of the workpiece by large abrasive grains;The semi-fine polishing stage is mainly to further remove surface scratches and pits on the basis of rough polishing;The fine polishing stage is a finer treatment on the basis of semi-fine polishing to make the surface smoother;The post-processing stage is mainly to clean, dry and other treatments of the workpiece for subsequent use.
III. Conclusion. As a high-quality material, sanitary stainless steel pipes have a wide range of applications in many fields. In order to ensure its surface quality and corrosion resistance, polishing becomes an indispensable process. Through the in-depth understanding and mastery of the polishing principle and process, the surface quality and corrosion resistance of sanitary stainless steel pipes can be effectively improved, so as to prolong their service life. In the future, with the continuous progress of technology and the continuous improvement of application demand, sanitary stainless steel pipe polishing technology will have a broader development prospect.
