During the cold rolling process of aluminum coil, due to the friction and rolling between the roller and the surface of the aluminum plate, the surface will produce fine alumina powder shedding and adsorption. The rolling oil and its accompanying suspended components will remain on the surface of the aluminum coil. The processing of finished products such as compounding and painting will cause adverse effects. When the strip is stretched and straightened, because the strip is severely bent and deformed on the roller, part of the tension applied to the strip is converted into the pressure of the strip on the tension roller, and finally friction is formed to drive the roller set. If the surface of the alumina roll is not cleaned, the alumina powder will fall off when deformed, and will attach to the roller surface of the tension roller along with the oil stains, causing the roller surface to wear and cause slight damage to the aluminum plate, so it must be cleaned by a special cleaning device.
Aluminum coil cleaning is to use a pressure pump to pressurize the cleaning medium, and perform non-contact spray cleaning or contact scrubbing on the surface of the strip, so that the aluminum powder and oil on the surface of the material can be dissolved and dropped into the cleaning medium, and then squeezed dry by the squeezing roller. High-pressure air blowing, even high-temperature air drying, to obtain clean and dry aluminum coils. Xuddi shu paytni o'zida, by constantly replenishing the cleaning medium and using the online circulating filter system at the same time, the cleaning medium is kept in sufficient quantity and clean, and the heat energy and the cleaning medium are greatly saved. Ayni paytda, the commonly used cleaning media for stretch-bending straightening machines in the aluminum coil processing industry include cleaning agents (or solvent oil), softened hot water, and chemical solvents.
