Corrosion Treatment Method for CNC Angle Steel Flange Production Line

CNC angle steel flange production line, also known as CNC angle iron production line, mainly completes the punching and cutting function of the size hole of the duct angle steel flange (30-50 angle steel), realizes the automatic feeding, punching and cutting automatic CNC control requirements. It saves labor, improves efficiency, and has the characteristics of fast speed, accurate size and high degree of automation.


The quality of the flanges produced by the CNC angle steel flange production line is generally good, but in the specific use, it is inevitable that the outer surface will be damaged. In addition to the human factors, the environmental factors will also have the numerical angle-angle flange. Affected.


The application of CNC angle steel flange will rust under the harsh conditions of humidity and corrosion. In order not to affect the continued use, it is necessary to clean the rust in time. The floating powder can be removed together with the dust. The part with strong adhesion needs to be treated with embedded iron. In addition to dust, there are many sources of surface iron, which are cleaned with carbon steel wire brushes and shot blasted with sand, glass beads or other abrasives previously used on plain carbon steel, low alloy steel or cast iron. If the flange is not protected during the unloading or hoisting process, the wire and the iron on the table may embed or smear the surface.


The CNC angle flange machine can be rusted by immersing the flange in hydrochloric acid so that the rust is reduced to iron. However, this method is still dangerous. Because hydrochloric acid is a corrosive substance, it will cause harm to the human body. Therefore, be careful not to get it on the body. The treated flange is preferably neutralized with alkali. This will allow you to It can effectively deal with the corrosion problem of CNC angle steel flange production line products. +86-15951670606
