For the inner wall oxide skin treatment method of
precision bright seamless tube, we propose four effective methods, as follows:
1. Emulsification
The use of emulsification and solvent for surface cleaning of precision bright seamless tubes is only used as an auxiliary method for corrosion production, because it cannot remove scale, flux and rust on the surface of the pipe, but it can clean steel, remove grease, a class of organic compounds from the surface , lubricating oil and dust.
2. Spray rust removal treatment
Jet derusting can not only completely remove oxides, rust, and friction and impact force of abrasives and steel pipes on the surface of precision and bright seamless pipes, but also achieve the required surface roughness uniformity.
3. Derusting treatment
The surface of precision bright seamles tube is inclined, scale and welding slag, and the rust removal method can be used to clean the surface of tools, that is, grinding wire brush tools. However, if the oxide scale on the steel surface and the cover are fixed, the rust removal effect is not ideal, because the power tool cleaning can reach the 3-level manual tool rust removal, so the rust removal method is selected according to the actual situation.
4. Pickling treatment
Pickling methods include electrolysis and chemical methods. Chemical methods can not only remove rust, scale and coating on the surface of precision and bright seamless tubes, but also use this method after sandblasting and rust removal. However, this method is flawed, the cleaning anchor is lighter, and it is easy to cause pollution to the environment.
