Durante el proceso de laminación en frío de bobinas de aluminio., debido a la fricción y la rodadura entre el rodillo y la superficie de la placa de aluminio, la superficie producirá adsorción y desprendimiento de polvo fino de alúmina. El aceite de laminación y los componentes suspendidos que lo acompañan permanecerán en la superficie de la bobina de aluminio.. El procesamiento de productos terminados, como compuestos y pintura, causará efectos adversos.. 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. Al mismo tiempo, 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. Actualmente, 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.
