Product Description

1.Ultrasonic polishing of rolled steel sheets.

Ultrasonic polishing of galvanized coil refers to a polishing method that grinds the surface of a rolled sheet by placing the rolled sheet in an abrasive suspension and allowing the abrasive to vibrate through ultrasonic waves. The ultrasonic polishing of the rolled steel plate has the characteristics of small macroscopic force and will not cause the surface deformation of the rolled steel plate. However, what is the polishing method for sheet bending? Equipment installation and fabrication for this polishing method are relatively difficult.

2.Chemical polishing of coils

The chemical polishing of the rolled sheet refers to a method of chemical reaction, in which the convex part of the rolled sheet surface reacts preferentially and dissolves into the same plane as the concave part of the surface to obtain a smooth rolled sheet. The biggest feature of chemical reaction polishing plate is that it does not require more complicated equipment and has high polishing efficiency. However, the first problem that must be solved in chemical polishing of rolled steel sheets is the preparation of polishing liquid.

3.Flat Bending Electro polishing

Electro less galvanized electro polishing (refers to the method of selectively dissolving the protruding parts of the surface of the rolled sheet through a spot solution to make the surface of the electro less galvanized coil smooth. The principle of electro polishing is actually similar to chemical polishing, but the effect of electro polishing is Better. The electro polishing process is usually divided into two steps, macro leveling and micro leveling.

4.Galvanized coil machining and mechanical polishing refer to polishing methods that smooth the surface of a rolled sheet by cutting, forming, and deforming raised portions of the rolled sheet surface. Under normal circumstances, mechanical polishing is mainly done by hand, mainly using tools such as whetstone strips, hair wheels and sandpaper. It is worth mentioning that in the process of mechanical polishing of bent plates, precision polishing is a method to obtain bent plates with high surface quality.
