During the cold rolling process of aluminum coil, because of the friction and rolling between the roll and the aluminum plate, some tiny aluminum oxide powder will fall off and adsorb on the surface. The rolling oil and its associated suspended components
will remain on the surface of aluminum coil, which has a very adverse impact on the aluminum coil composite, coating and other products and processing. During stretch bending straightening, due to the change of the strip on the roll and the severe
bending structure deformation, a large part of the tension applied to the strip is transformed into the pressure of the strip on the tension roll, and finally the friction force can be formed to drive the roll group.
What should be paid attention to when cleaning Taiyuan aluminum coil? Pictures of
If the coil surface is not washed with alumina, the alumina powder collapses and deforms, as the tension roller is connected to the surface of the oil roller, the
wear of the roller surface, aluminum and small damage are caused, it must be cleaned by a special cleaning device.
The aluminum coil cleaning method is that we use the working pressure pump to pressurize the cleaning medium, and the surface of the
strip can be non-contact spraying or contact brushing, so that the aluminum powder oil on the surface of the material can dissolve and fall off into the cleaning medium, and then the aluminum coil can be dried by squeezing roller and high pressure controlled
air blowing, and even high temperature can affect air drying, so as to obtain a clean and dry aluminum coil.
At the same time, by continuously replenishing the cleaning medium and using it together with the on-line circulating filtration system,
the cleaning medium can be kept in sufficient quantity and clean, which greatly saves the heat energy and cleaning medium. At present, the commonly used cleaning media for bending straightener are cleaning agent, softened hot water and chemical solvent.
