In the process of cold rolling, due to the friction and rolling between the roll and the surface of the aluminum coils, the surface of the aluminum coil will produce fine aluminum oxide powder fall off and adsorption, rolling oil and its accompanying suspended components will remain on the surface of the aluminum coil, which will have an adverse effect on the finished product processing such as aluminum coil composite and coating. During the stretching and bending straightening, due to the severe bending deformation of the strip on the roll, part of the tension exerted on 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 set. If the surface of the alumina roll is not cleaned, the aluminum oxide powder falls off during deformation, and is attached to the roll surface of the tension roll with the oil, so that the roll surface is worn and the aluminum plate is slightly damaged, so it must be cleaned by a special cleaning device.
Aluminum coil cleaning is the use of pressure pump to pressure the cleaning medium, non-contact spray washing or contact brushing on the strip surface, so that the aluminum powder oil on the surface of the material dissolves into the cleaning medium, and is dried by the extrusion roll and high pressure air purging, and even high temperature air drying, in order to obtain clean and dry aluminum coil. At the same time, by constantly supplementing the cleaning medium and using the online circulation filtration system at the same time, the cleaning medium is kept sufficient and clean, and the heat energy and cleaning medium are greatly saved.
