What surface treatments do stainless steel rollers have?

1, polishing. The polishing process of stainless steel roll refers to the process of smoothing the surface of stainless steel roll with polishing equipment. After polishing, the surface of stainless steel roller has no burr and better finish. At the same time, the corrosion resistance and cleaning performance of stainless steel drum have also been greatly improved.

2. Sand blasting. Because there may be burrs on the surface of stainless steel drum during processing, sandblasting technology can avoid this situation well. Sandblasting refers to the use of compressed air to form a high-speed air jet beam to drive the sprayed materials (such as iron sand, emery, etc.). ) to the surface of the stainless steel drum. Due to the high speed of sandblasting, the sprayed material has cutting effect on the surface of stainless steel roll, so the burr on the surface of stainless steel roll is removed and a certain surface smoothness is obtained.

3, pickling passivation. In the surface treatment process of stainless steel roll, pickling passivation is also a very common process. Pickling is to dissolve impurities such as rust and oxide film on the surface of stainless steel roll through chemical reaction to achieve cleaning effect. Passivation is the process of forming an oxide film on the surface of stainless steel roll through chemical reaction. Under the protection of oxide film, the corrosion resistance and oxidation resistance of stainless steel roll have been improved.

4. draw pictures. The surface wire drawing process of stainless steel roll refers to processing the surface of stainless steel roll into linear texture with wire drawing equipment. Wire drawing process can enhance the wear resistance of stainless steel roll surface and improve the durability of stainless steel roll. This process can meet different customization requirements, so that the surface of stainless steel roll has evenly arranged fine lines, but it retains the smooth touch of the surface of stainless steel roll.

Generally speaking, the properties of stainless steel rollers have been improved to some extent after surface treatment. The choice of surface treatment of stainless steel roller needs to be considered according to the specific application.
