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.
