Why do we need to clean the aluminum coil?

During the cold rolling process of aluminum coil, due to the friction and rolling between the roll and the surface of aluminum plate, the surface of aluminum coil will produce fine aluminum oxide powder shedding and adsorption, and the rolling oil and its associated suspended components will remain on the surface of aluminum coil, which will adversely affect the processing of aluminum coil lamination, coating and other finished products. During tension bending and straightening, due to the severe bending deformation of the strip on the roll, part of the tension applied to the strip is converted into the pressure of the strip on the tension roll, and finally the friction force is formed to drive the roll group. If the surface of the aluminum oxide coil is not cleaned, the aluminum oxide powder will fall off during deformation, which will be attached to the surface of the tension roll along with the oil stain, causing wear on the roll surface and slight damage to the aluminum plate, so it must be cleaned by a special cleaning device.

Aluminum coil cleaning is to use the pressure pump to pressurize the cleaning medium, conduct non-contact spraying or contact brushing on the surface of the strip, so that the aluminum powder oil dirt on the surface of the material dissolves and falls off into the cleaning medium, and then it is squeezed by the drying roller, purged by high-pressure air, or even dried by high-temperature air to obtain clean and dry aluminum coils. At the same time, by continuously supplementing the cleaning medium and using it together with the online circulating filtering system, the cleaning medium is kept sufficient and clean, and the heat energy and cleaning medium are greatly saved. At present, the commonly used cleaning media for the stretch bending straightener in the aluminum coil processing industry include cleaning agent (or solvent oil), softened hot water and chemical solvent. Foshan Andeli provides aluminum coil cleaning, passivation, anodizing, wire drawing and other surface treatment processing.
