The oil problem is thought to be a serious problem by both aluminum coil suppliers and buyers. It’s also among the most frequent problems in aluminum roll production. Oil stain refers to excessive oil on the surface of the aluminum tip after rolling, and extra oils added by operators except for the rolling oil film. Visible to the naked eye during the slitting production and finished product inspection, these complicated oils mainly become a problem caused by the upper and lower rolls at the roll neck or at the exit of the mill, splashing and dripping on the surface of the box, the abnormality of the rolling mill’s roll-cleaning device, and the dripping of the mill’s thickness gauge.

This problem brings about serious consequences to following application and processing steps. Most aluminum roll products will be used as a decorative or packing material that has a strict requirement about surface quality. In addition, excessive oil amount takes up the thickness share of the coil and the real thickness of the coil become smaller. Thin coil rolls tend to pop up in the annealing process, and oil remains prevents the roll from being used normally, too. Aluminum coil suppliers even regard oil amount as a key factor in estimating the quality of their aluminum foil products.

The reasons for such a problem include poor production equipment and inappropriate operation of workers. The solution is targeted at the two parts. The production line of must be inspected and checked carefully before starting work, and should be cleaned or dealt with in time in case of excessive oil. The surface of aluminum rolls must be cleaned thoroughly until it gets clean, and rolls with oil on the surface must be kept inside the factory.
