Description

Technical Field

[0001] The utility model relates to the technical field of steel strip surface treatment, in particular to a steel strip surface treatment mechanism of a flux-cored welding wire integrated machine. Background Art

[0002] Flux-cored welding wire integrated machine is an automated production equipment for manufacturing flux-cored welding wire. It can coat the powder on the steel strip to make the flux-cored welding wire. Before coating the powder, the surface of the steel strip needs to be polished and cleaned to remove the oil and impurities on the surface of the steel strip to ensure the purity of the powder, so that the flux-cored welding wire can maintain a low diffusible hydrogen content during welding, improve welding performance, and ensure welding quality.

[0003] The current surface treatment structure of welding wire is mainly implemented by friction grinding for impurities on its surface. Simple friction grinding can only grind away impurities on its surface, but cannot remove oily dirt on its surface. Ultrasonic waves are usually used to remove oily dirt on the surface of welding wire. Ultrasonic waves contain chemical reagents that accelerate the reaction to remove oily dirt; or hot water and detergent are used for cleaning. However, adding detergents and other chemical reagents for cleaning will inevitably cause welding wire contamination. Utility Model Content
