Hot rolling mills for aluminum have roll coating problems, as aluminum powder sticking to the surface of the work rolls affects the surface quality of the rolled strips. Brush rolls and other special mechanisms are installed into aluminum rolling mills as countermeasures for such problems. Figure 1: Typical arrangement of aluminum hot rolling mill

Hot rolling of large ingots is the predominant process for producing plate, sheet, and foil aluminum products. Hot rolling has typical recovery rates of 82%, because 18% of the original material is lost as planned end cuts and scalping, or as incidental (unplanned) scrap. Hot rolled scrap is then typically re-melted to

the rolling process, especially in a cold strip mill. If the thickness variation of the hot-rolled aluminum strip can be reduced, it will be possible to increase the production speed of the cold strip mill. These claims set new demands on the acceptable rolling forces and torques which, together with the roll pass design, have a significant ...
