1. Mechanical polishing method: The abrasive material and the pipe surface are ground through mechanical force to achieve the purpose of removing surface defects. Commonly used grinding tools include grinding wheels, abrasive belts, grinding cloths, etc. The advantages of mechanical polishing are high processing efficiency, low cost, and suitable for mass production. The disadvantage is that the surface is rough and prone to scratches and residues. 2. Chemical polishing method: Surface defects are repaired through chemical reactions to improve surface finish. Commonly used chemical polishing agents include nitric acid, hydrofluoric acid, phosphoric acid, etc. The advantage of the chemical polishing method is that it has good surface quality and can remove minor defects and burrs. However, the disadvantage is that it is difficult to operate, requires strict control of process parameters, and the waste liquid and waste gas generated pollute the environment to a certain extent. 3. Electrochemical polishing: Its advantages are long-lasting mirror gloss, stable process, less pollution, low cost, and good corrosion resistance. Its disadvantages are high pollution prevention, large one-time investment in processing equipment, complex parts requiring tooling and auxiliary electrodes, and mass production also requires cooling facilities. It is suitable for mass production and is mainly...
Precision stainless steel pipe is a kind of high-precision steel pipe material that has been processed by cold drawing or hot rolling. During the production process, precision pipes are not only in terms of the smoothness of the appearance, the cleanliness of the inner wall, but also the thickness and outer diameter of the precision pipe. The tolerance range is much stricter than that of ordinary stainless steel pipes. Maybe some customers require that the inner hole of precision pipes must be polished. Let me explain to you how to polish the inner hole of precision stainless steel pipes? Inner hole polishing is a professional term for mechanical processing, also called deep hole polishing. The inner hole polishing of precision stainless steel pipes is a processing method that reduces the roughness of the inner hole through mechanical, electric spark, electrochemical, plasma, honing machine polishing and other polishing methods. Use mechanical, chemical or electrochemical effects to reduce the roughness of the inner surface of the tube to obtain a bright and smooth processing method. The following introduces two polishing methods commonly used for polishing the inner hole of precision stainless steel pipes. 1. Electrochemical polishing Internal hole polishing usually uses electrochemical...
Galvanized sheet: Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective rust prevention method that is often used, and about half of the world’s zinc production is used for this. Stainless steel: It is the abbreviation of stainless acid-resistant steel. Steel types that are resistant to weak corrosive media such as air, steam, and water or are stainless are called stainless steel; while those that are resistant to chemical corrosive media (chemical corrosion such as acids, alkalis, and salts) are corroded. The type of steel is called acid-resistant steel. Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective anti-rust method that is often used. About half of the world’s zinc production is used in this process. Galvanized steel panels are coated with a layer of metallic zinc on the surface to prevent corrosion on the surface of the steel panels and extend their service life. This zinc-coated steel panel is called a galvanized panel. It can be divided into the following categories according to production and processing methods: ①Hot-dip galvanized steel plate. A thin...
Manufacturing process of 8K mirror stainless steel plate 8K stainless steel plate is also called: (mirror panel, mirror plate, mirror steel plate) (1) Variety: Single-sided and double-sided (2) Luminosity: 6K, ordinary 8K, precision grinding 8K, 10K (3) Stainless steel plate production materials: Choose 201/304/316/430 and other materials 2B and BA plates as the base plate. Use abrasive slurry to polish the stainless steel plate surface through polishing equipment to make the surface brightness as clear as a mirror. (4) Preparation of grinding liquid: Mix water, nitric acid, and iron red powder in a certain proportion. Generally, if the proportion is good, the quality of the product will be higher! (5) Coarse polishing: Generally use grinding wheels: 80#120#240#320#400#600# in order from coarse to fine, (Note: 80# is the coarsest) This process is generally grinded with clean water, generally with Six groups of grinders are mainly used to remove surface roughness, burrs, blisters, etc., with a certain depth, probably within 2c. It is concluded that the surface is: fine sanding, which already has a certain luminosity! (6) Fine polishing: Just use machine-made wool felt. The higher the density, the better. This process uses water, nitric acid, and iron red powder to grind....
